Field Note: Rx for Restoration? Fire??? Yes, Indeed!

May 3, 2023 / Cam Mannino / 2 Comments

Some of the fire crew gathered under the Big Oak during a pause in this spring’s burn. Note that the crew kept the fire from singeing the oak’s trunk, though it’s fire-adapted like all oaks. It was done out of deference to all the changes the Big Oak has experienced this year. Photo by Ben VanderWeide.

Eight years ago, when I first heard about prescribed burns, I thought “What? That’s pretty counter intuitive. Why would anyone apply fire to help plants?” Luckily, I learned about these restorative burns from Dr. Ben VanderWeide, our township stewardship manager; he had the answers.

After recent highly successful prescribed burns at Bear Creek Nature Park, I thought it might be time to discuss this seemingly strange process once more.

[Please Note: Due to an absurd mistake on my part, nearly all my photos of this spring’s Bear Creek burn were lost. I heartily thank volunteers Bob Schrader and John Reed as well as Grant VanderLaan and Ben for sharing their photos for this blog. My apologies to the fire crew for messing up big time!]

The History of Fire in our Prairies

For thousands of years, rolling prairies and oak savannas, dotted with native wildflowers and widely spaced oaks, carpeted our area of southeast Michigan. Lightning strikes periodically set the trees and fields ablaze, creating large wildfires. The Anishinaabek people that lived here also made regular use of fire, clearing land for crops and attracting game with the tender new plants that rise after a fire.

As a result, our native plants became fire-adapted. They “learned to live with” fire and even benefit from it. Trees like the oak in the photo above developed thick bark, especially at the base. Some like jack pines (Pinus banksiana) even require fire to trigger their pine cones to release seeds. For others the chemicals in smoke, the heat of the fire itself, or removing accumulated thatch cues dormant seeds to germinate.

Fire Becomes an Ally in Restoration

Today, while renewing our native plants, fire also discourages or even eliminates many aggressive non-native, non-productive plants that invaded our fields, forests, and remnant prairies after agriculture ended. Their leaves and fruits are either toxic or drastically less nutritious for our native birds, native insects and their caterpillars. Fire acts as an ally in restoration by knocking back these plants that didn’t evolve with fire and therefore never adapted to it. Other invasive plants like crown vetch, Phragmites, invasive bittersweet, and swallow-wort respond positively to fire, so burning is often paired with other management techniques if these plants are found in area to be burned. Our native plants can then provide the nourishing, healthy food on which our wildlife depends.

Planning the Prescribed Burn

As Stewardship Manager, Ben plans the burns long ahead of time, choosing areas with good potential for restoration, especially ones with invasive and/or non-native vegetation. If the burn will encompass flat or gently sloped land, Ben often uses his staff plus trained volunteers to set and manage the fire. (Look for our annual training day each February if you’re interested!) He hires licensed contractors to conduct burns that involve large areas, forests with lots of dead wood, or steep hills which present more challenges. [Please note that any prescribed burn should only be done by trained personnel! Detailed knowledge and experience are required for a safe burn.]

*Volunteer fire crew preparing to burn, March 2016.*

Volunteers meet with Ben and the stewardship crew before the fire to review his burn plan in detail. The Parks and Recreation Commission provides our local crew with hard hats, fire-resistant clothing and face shields, as well as walkie-talkies so that crew members can communicate with one another during the burn. All members are trained to acknowledge instructions given to them by the crew leaders and to report any changes in their location or fire behavior during the burn. Once the neighbors have been notified, prescribed fires occur on days with the right wind speed, wind direction, and humidity. A fire weather forecast also gives the crew clues about how well the smoke will rise and disperse. Before the burn begins, the crew removes logs and large fallen branches near the edge of the burn unit and/or douses them with water from backpack canisters that can be refilled from a large tank carried in the crew’s truck .

Ben monitors the wind before and during the burn to prevent the smoke as much as possible from carrying into nearby neighborhoods. The natural areas stewardship staff creates or checks “burn breaks” around the perimeter of the “burn unit” days, weeks, or months before the burn day. A burn break can be pond, stream, or other naturally occurring feature, or it might be a trail, road, parking lot or other human-constructed thing that doesn’t have fuel for the fire to burn across. Burn breaks are also created around bird nest boxes, utility poles, or other fire-sensitive objects inside the burn unit.

Igniting and Monitoring the Fire

The crew first ignites the fire on the downwind side of the burn unit, creating a slow “back burn” that creeps against the wind into the burn unit. Fire slips in droplets from the tip of a drip torch as crew members walk slowly around the edges of the unit, carefully starting the fire. The crew allows the fire to create a wide burned area on the downwind side before moving around to the edges, or “flanks.”

As the crew spreads the fire around the flanks, it slowly spreads inward toward the center of the burn unit.

The fire burns around and under trees and shrubs. Most larger trees have thick bark that easily protects them from a quickly passing fire. Many small trees and shrubs are top-killed by fire, but most resprout vigorously afterward. In fact sumacs, willows, and some other native shrubs grow better if they are occasionally pruned back by fire. In my photos below, fire burned right under a fire-adapted small oak during the second burn and when it passed on, the little oak and its spring leaf buds showed no damage. If small oaks are top killed by fire, they resprout vigorously from their huge roots.

The fire travels right across a small oak which Grant had sprayed with water a few minutes earlier.

While the basic tools of prescribed burns are water tanks and drip torches, some crew members carry tools like a flat-backed fire rake or a fire flapper to separate burning embers or rub sparks or embers into the ground. Once the fire dies down, these tools and the water tanks are used to put out any smoldering material during “mop up.”

Wondering about the Impact on Wildlife?

I worried about this, too! But having witnessed many burns at this point, I’ve learned that once the smoke starts, creatures move quickly out of the burn units. The fire crews never burn a whole park in one day, so there are always unburnt areas in the park where moles, snakes, mice and insects can find refuge quickly. In fact, the crew tries to work the fire upwind so that rabbits, squirrels and other creatures smell the smoke sooner and have time to escape to other areas in the park or beyond.

Some animals and insects retreat to underground nests, like the ants. Remember that our native insects have been dealing with fire for thousands of years and react quickly to smoke. Our pollinators and their caterpillars will benefit greatly in future weeks from the increased population of nutritious native plants created by the longer growing season and the natural fertilizer as the nutrients in the dead plant material are returned to the soil. Many native plants flower more vigorously after a burn, creating a bountiful buffet for our pollinators.

Of course, I’ve also seen a Red-tailed Hawk (Buteo jamaicensis) and an American Kestrel (Falco sparverius) high in the trees calmly ignoring the smoke blowing across their eyes as they watch carefully for possible prey.

At a prescribed burn in 2016, I saw a female Red-tailed Hawk looking out into a burned field with an intense stare!

Ben checked one of the burned fields at Bear Creek a few days after the March 21 burn this spring, and found American Robins, Red-winged Blackbirds, and others enjoying the easy food options on the Western Slope. Here’s his video of what he heard as he looked across the blackened field! Quite a chorus! The nearby unburned fields were much quieter.

Smaller birds and other animals benefit by foraging in the burn unit after the fire is out. The morning after the first burn, I came back to find American Robins (Turdis migratorious) all over the fields, snatching up worms or insects and a few Dark-eyed Juncos (Junco hyemalis) busily pecking their way around the blackened areas.

Sowing Native Seed After A Burn

After the second burn at Bear Creek Nature Park this year, Ben sent this assessment to volunteers and staff:

“The burn jump-started the next phase of our restoration work in these burn units! Today [March 31, 2023] between breaks in the rain, we will spread a locally-collected native seed mix on the burned areas to help increase the native plant diversity. It usually takes 3-5 years for plants growing from seed to establish and become noticeable, so you won’t see the results of this seeding for a while. You will see the response from naturally occurring native plants, and from native plant seed that we spread years ago! Look for more growth and flowering from our native wildflowers and prairie grasses this summer!”

Ben sowing seed on the western slope at Bear Creek in 2018. We may see native blooms from this seed this summer.

More from Ben: “In a few weeks you’ll start to see green growth emerging in the burn units. Early season burns often take a bit longer to green up compared to areas burned in April or early May. Later this spring and early summer we’ll scan through the burn units to look for invasive plants like crown vetch, teasel, and swallow-wort. Later summer or early fall the stewardship crew plans to scan through the burn units to spot treat invasive shrubs that were top-killed by the fire. Next spring we hope to repeat the burn, seed, and invasives monitoring sequence. This process has produced good results as an alternative prairie restoration technique for old field/pasture in Wisconsin (check out this webinar for more info – https://www.youtube.com/watch?v=hvMy–MMM2c), so we’re trying it in the fields at Bear Creek Nature Park.”

Ben was so right about the greening up process. Here’s the Western Slope after the March 21 burn and what it looked like about a month later on April 22.

Fire’s Big Payoff

As Ben says above, planting native seeds means a 3-5 year wait for the full bloom to appear while the plants grow deep roots. But if conditions are right, the result can be just amazing and well worth the wait!

Here’s one example that I cherish. In April of 2014, Ben burned the Eastern Prairie at Charles Isley Park. I didn’t get there in time to get a photo that year, but on the left below is a burn photo there from another year. After the 2014 burn and other work to prepare the field, Ben planted native wildflower and grass seed in fall 2015. And look at what a glorious show we had by 2018!

Of course every park, every habitat is different, so we can’t quite expect such a magnificent bloom every time. And the flowers calm down and thin out a bit over time as they sort out their competition and wait for another fire. But I think this 2014 to 2018 transformation is what made me a convert to prescribed fire.

Sometimes I find an even bigger thrill simply seeing a native plant emerge whose seeds were waiting in the soil for years, or small, stunted plants that persisted for years under invasive shrubs. Freed of thatch and invasive shrubs, warmed, fertilized, showered with rain, they finally emerge again into the sunlight. And I love that renewal. Here are just a few wildflowers from different parks that have staged a comeback after prescribed burn and other restoration efforts over recent years.

The Inspiring Persistence of Nature

Native trees, shrubs and wildflowers are an inspiration for me. They’re tough, seasoned survivors, having lived here for thousands of years while coping with Michigan’s changeable weather and rocky, glacier-scraped soil. Native Wood Poppies (Stylophorum diphyllum) in our backdoor garden, some buried unceremoniously under huge piles of dirt by utility workers shortly after planting, just came back and kept on blooming. When our native Clematis (Clematis occidentalis) arrived from the grower looking like a bent, possibly dead stick, I planted it anyway. It bloomed with lavender blossoms during June last year. Insects skeletonized the leaves of our Zigzag Goldenrods(Solidago flexicaulis) its first year, but they leafed out and bloomed a year later.

Once native plants establish their deep roots, they take care of themselves and their needs are few. They can thrive in poor soil, tolerate drought, fight off predatory insects with their own chemicals and insist on survival without frequent watering or fertilizer. And as you can see in our parks, they can even thrive after fire, for heaven’s sake!

It’s a sad fact that native plants face a host of challenges caused by us, the brilliant but heedless species, Homo sapiens. Invasive trees, shrubs, grasses and flowers from afar were transported or purchased here by you, I and our forebears. When they escape from our yards into natural areas, they transform our fields and woodlands into dense thickets of a few non-native species. Our native habitat relies on pollinators for survival, but their numbers continue to plummet because we unwittingly chose, and in most cases continue to choose, pretty non-native plants whose leaves malnourish or kill caterpillars, the next generation of insects. And of course few of us have seriously reduced our reliance on fossil fuels which create the newly extreme and erratic climate that wreaks havoc on the complex relationships that sustained nature in a healthy, finely tuned ecosystem for millennia.

But now we know, right? And here in Oakland Township, we’re doing our best to provide native plants with a new lease on life. First, we preserve open areas and then we work to restore them to health. So when Ben and the stewardship crew ignite their drip torches, I’m delighted. We’re taking nature’s side, trying to restore native habitats in our parks and for many of us, in our yards and gardens. That’s the side I want to be on – and I’m betting you do, too. I mean, it makes so much sense! After all, nature can survive without us, but we definitely cannot survive without nature! So let’s just do what we can with what we know now. Let’s see how much progress we can make in our little green corner of the world before we leave it to the next generation.

Migration Miracles: How Migrating Birds Find Their Way to Us … and Survive the Journey

April 11, 2023 / Cam Mannino / 5 Comments

*Sandhill Crane in flight over Stony Creek Ravine Nature Park*.

They’re coming our way. And others are bidding us farewell. The spring bird migration is under way and will really gain steam in early May. Are you curious about how many birds flew through the night over Oakland County yesterday? Here’s a great tool from Cornell University’s Ornithology Lab that can give you a data-based estimate! (Thanks to birding friend Vinnie Morganti for the link!)

The Dark-eyed Juncos (Junco hyemalis) and Tree Sparrows (Spizelloides arborea), who nest in colder climates, are beginning to depart from the hedgerows and from under our feeders as they wing their way to their northern breeding grounds. Bufflehead dabbling ducks (Bucephala albeola) showed up on Cranberry Lake in mid-March as they made their way through Michigan to their nesting grounds that extend from Ontario to Canada’s Northwest Territories. And of course, the hoarse, ancient cries of the Sandhill Cranes (Antigone canadensis) now draw our eyes skyward. (Click on photos below to enlarge.)

I’m always impressed by the ability of birds to survive the ordeal of migration, successfully navigating their way twice each year across the country and sometimes far beyond. This spring a lot of questions bubbled up in my winter-weary mind.

How does the tiny hummingbird beat its wings thousands of times on its way to Central America without expiring from exhaustion? How do fledglings find their way when they travel without adults, which happens more often than not? How do birds flying nonstop over oceans eat and sleep? And what’s up with birds using the earth’s magnetic field to navigate? I sure can’t perceive the earth’s magnetic field!

Recently, while doing some spring cleaning, I came across an article that I’d saved which gave me some possible explanations and some resources to go further. (See references below.) So I wanted to share with you the astounding and somewhat bizarre adaptations that allow our avian neighbors to successfully make such arduous journeys.

First, a big Thank-You! My photographer friends, Paul Birtwhistle and Bob and Joan Bonin have again generously shared some of their wonderful photos for this blog. My heartfelt thanks to all three!

So How Did This Whole Migration Pattern Get Started, Anyway?

Doesn’t semi-annual migration seem a bit extreme? I mean, why don’t birds just stay in warm regions all year ’round happily eating and breeding? (I’m glad they don’t, though!) The Cornell Lab of Ornithology describes two theories: the Northern Home theory that northern bird ancestors moved south little by little as ice ages advanced, or the Southern Home theory that southern bird ancestors followed the ice north as it retreated. According to a recent University of Michigan study of the evolutionary lineage of 800 species of North American song birds, the Northern Home theory seems more likely. (Very cool detail about this subject at this link! Click on the words “Evolution of Bird Migration” at the top left.)

Birds have continued to migrate for eons because of the basics: food and breeding opportunities. Temperate zones like Michigan are very buggy places. Our inland wetlands and shorelines produce a glorious abundance of insects and their caterpillars each spring and summer. Just look at the meal this Song Sparrow (Melospiza melodia) found in one of our parks! Quite a haul!

So when daylight lingers in spring or shrinks in autumn, birds notice the change and start feeling restless. Even captive birds in scientific studies evidence migration restlessness, which is known among researchers by the German name zugunruhe. As the season approaches, they eat more and later into the evening. Their sleep decreases by as much as two-thirds in some species. (Sounds familiar somehow. Maybe human “snow birds” are experiencing zugunruhe?)

The other big draw is mating, of course. Favorite stopovers bring together migrating birds of the same species, which means a more diverse choice of mates. Let’s hear it for diversifying the gene pool!

And then there’s the “housing market”; early birds enjoy a greater selection of the preferred, sometimes scarce, nest sites.

OK, So How Do Birds Prepare for Migration?

It’s tough to generalize about bird migration. Consider that some travel long distances, like the Ruby-throated Hummingbird (Archilochus colubris) who flaps its tiny wings to reach Central America, or the Magnolia Warbler (Setophaga magnolia) who sets off for the Caribbean. Others travel short distances, like Eastern Bluebirds (Sialia sialis) and American Robins (Turdus migratorius) who simply move just far enough in winter to find open water and more food.

The Hummingbird can double its weight quickly before migration. Photo by Paul Birtwhistle.

Many songbirds, like the Rose-breasted Grosbeak (Pheucticus ludovicianus), make their way at night to avoid migrating predators like the Cooper’s Hawk (Accipiter cooperii), which migrates in daylight. Also, according to the Audubon Society, “Free of daytime thermals [rising warm air], the atmosphere [at night] is more stable, making it easier to maintain a steady course, especially for smaller birds such as warblers that might fly as slowly as 15 miles per hour.”

The Rose-breasted Grosbeak migrates at night riding tail winds as much as possible . The darkness hides them from many predators.

Some migrators fly in single species flocks, like the Snow Buntings (Plectrophenax nivalis) that arrive in the fall from the Arctic to spend winters in Michigan. Their plumage is whiter in the snowy north to camouflage them while breeding. During their winter visit here, their plumage includes more brown, making them less visible in fallow farm fields and open prairie. Others, like the Greater (Tringa melanoleuca) and Lesser Yellowlegs (Tringa flavipes) make their way north in mixed flocks during spring migration.

According to Scott Weidensaul, author of A World on Wings: the Global Odyssey of Migratory Birds, even if huge numbers of birds are aloft together, a migrating songbird flying at night, “does not fly in cohesive, coordinated flocks; each is migrating on it own.” House Wrens (Troglodytes aedon) and Red-eyed Vireos (Vireo olivaceus), for example are lone nighttime migrators.

A House Wren negotiates its migration from Florida on its own.

Given all that that diversity, here’s what I’ve gleaned so far about how birds prepare.

They Fatten Up Big Time!

*A large flock of Canada Geese (*Branta canadensis) *here in Oakland Township* *building up their fat stores for migration.*

Birds really lard up for migration. Experienced naturalist and local bird bander, Allen Chartier, checks the weight of each bird he bands and gently blows the breast feathers aside to actually see the fat layer. He told me in a helpful email that our Ruby-Throated Hummingbirds, which normally weigh about 3 grams during breeding season can weigh more than 5 grams as they leave Michigan. They need to keep bulking up along the way and amazingly can double their normal weight in about a week just before heading across the Gulf of Mexico in the autumn or the Yucatan in the spring.

Blackpoll Warblers (Setophaga striata) transit across our state twice a year and Allen says they, “… undergo a long water crossing, sometimes from the mid-Atlantic coast down to Venezuela, non-stop. Normally they weigh 10-11 grams, but can put on enough fat to more than double their weight for these multi-day flights.” He reports that “in the Great Lakes, I have had Blackpoll Warblers that weigh more than 20 grams.” Fat is clearly the essential fuel for bird migration!

*The Blackpoll Warbler can fly over the Atlantic for 3 days nonstop on its way to its wintering grounds.*

As author Scott Weidensaul points out, “By any typical measure, a migratory bird ready for travel ought to head to the ER, not the skies.” But he says, unlike seriously overweight humans, fattened-up migrators are not plagued by increased risk of hypertension, heart disease, diabetes or stroke. Weidensaul says that “Researchers hope that insights from avian physiology may help may help unlock new treatments and preventive approaches in people.” I hope so too!

They “Grow or Jettison their Internal Organs on an As-needed Basis!”

The quote above from Scott Weidensaul’s book just blew me away. The internal organs of birds actually shrink and expand for migration? Yes! “Internal flexibility is actually common among migrants … a thrush or catbird, feeding on the dogwood berries in a corner of the backyard, has undergone a late summer expansion of its intestines to squeeze every calorie from lipid-rich fruit.”

*This digestive tract of this Gray Catbird (*Dumetella carolinensis) feeding in September 2019 at Bear Creek Nature Park would have extended as the the fall began in order to get as much polyunsaturated fat as possible from the pulp or seeds within the berries it’s eating!

Migrating birds, which need to travel non-stop over oceans or deserts for long distances, shrink their digestive organs since they’re expendable when they can’t stop to feed. But their hearts, lungs and pectoral muscles grow larger, and do so without exercise! On arrival, the digestive organs make a comeback that allows them to start feeding again. Imagine! Transforming organs!

The little Chestnut-sided Warbler (Setophaga pensylvanica) below, photographed by Paul Birtwhistle in Costa Rica, may not have needed such drastic transformation for its nonstop trip across the Gulf of Mexico. I couldn’t find a definitive answer to that but it definitely burned a lot of fat! According to Cornell Lab of Ornithology’s subscription website, Birds of the World, a Chestnut-sided Warbler in non-breeding plumage could have weighed 10 -12 grams when it left the U.S. coast. But these birds are recorded as weighing only about 8 grams when they reach Central America, having lost most or all of their stored fat on their nonstop flights across the Gulf of Mexico.

This Chestnut-sided Warbler in Costa Rica probably lost a lot of weight flying over the Gulf of Mexico to Costa Rica. I’d say a soothing bath was called for! It will probably take a more leisurely trip around the edge of the Gulf on its way to us this spring. Photo by Paul Birtwhistle.

Weidensaul also reports that both male and female birds shrink their sexual organs for fall migration. Anything to make flying lighter and easier, I guess! Allen Chartier wrote, “Ever since humans began preparing “study skins” for museums, more than 200 years ago, it was discovered that during the non-breeding season the gonads of birds shrink in size, to maybe 10% of the size that they are in the breeding season. It was figured, eventually, that this was to reduce weight for migration, and allow for more body fat to be laid on for migratory flights.” Their gonads are ballooning right now, which is why we are beginning to hear that robust morning chorus in the spring!

Once They Start Moving, How in the World Do They Navigate?

*A flock of migrating Tundra Swans (*Cygnus columbianus) *called to each other as they flew over Cranberry Lake Park. Photo by Bob Bonin*.

In her lively and well-researched New Yorker article, “Where the Wild Things Go: How Animals Navigate the World,” (April 5, 2021), Kathryn Schulz wrote: “A bird that migrates over long distances must maintain its trajectory by day and by night, in every kind of weather, often with no landmarks in sight. If its travels take more than a few days, it must compensate for the fact that virtually everything it could use to stay oriented will change, from the elevation of the sun to the length of the day and the constellations overhead at night. Most bewildering of all, it must know where it is going — even the first time, when it has never been there before – and it must know where that destination lies compared with its current position.” Wow.

Like humans with our much more limited ability to orient and navigate, birds use a variety of basic navigation strategies, and different species may use a combination of them. Kathryn Schulz lists as strategies: sight, sound or even scent cues, landmarks (mountain ridges, coastlines), compass orientation or vector navigation (stringing together multiple orientations (e.g. south and then southwest for a precise distance) or dead reckoning (calculating based on bearing, speed and time elapsed from a previous location). But she points out, “… to have a sense of direction, a given species might also need to have other faculties, something like a compass, something like a map, a decent memory, the ability to keep track of time, and an information-rich awareness of its environment.” And Weidensaul adds to the list: the patterns of stars around Polaris (the North Star) and the movement of “bands of polarized light that are invisible to us but easily seen by birds.” Wow, again! All that in one small skull!

According to Weidensaul, “Migratory birds grow fresh neurons before autumn migration” and scientists have correlated longer migrations with more neuron growth, presumably as an aid to navigation. The neurons also increase according to whether birds travel individually or in flocks. Warblers which generally fly alone show increases in the hippocampus which processes spatial information and memory. Birds in large migrating flocks see most of the increase in regions of the brain that may be more important for noticing and understanding the actions of other birds.

Researchers believe that a bird’s general destination may be defined by instinct, especially in young birds, many of whom make their first trip alone or with other juveniles. But learning clearly occurs during their first flight with or without adults and plays its part in perfecting the best route from then on.

But what I wanted to know was, how do some migrating birds create and use a mental map of the earth’s magnetic field? I kept finding references to their ability to do so, but no one told me how! Well, Weidensaul had an answer which he says “most experts accept.”

*This little Wilson’s Warbler could have navigated from Central America to Tawas City, Michigan using a starlight map of the earth’s magnetic field in its retina! What a feat!*

Imagine the little Wilson’s Warbler (Cardellina pusilla) in the photo above glancing upward at the stars as it flies through the night from Central America to where I saw it in Tawas City, Michigan. As I understand it, photons of the stars’ blue light hit specialized cells in the bird’s retina containing molecules of a protein called cryptochrome. (Love the Superman sound of that!) Those molecules react by thrusting one of their electrons into a neighboring molecule and the two become connected (“entangled” in scientific jargon) and magnetic. (That’s the quantum mechanics part which is a bit beyond me.) As light continues to stream in, multiples of these paired molecules build a map of the magnetic field within the bird’s eye. Scientists think the map may appear as a “dim shape or smudge — visible as the bird moves its head, but not opaque enough to interfere with normal vision — that shifts with the bird’s position relative to the ground and to the inclination of the magnetic field lines arcing out of the planet” (Weidensaul). Evidently, birds can orient themselves within that map to help find their way to their destination. Many of us humans have a tough time reading a road map!

If my brief summary leaves you with more questions than answers, you’re in good company. Even scientists don’t completely understand how cryptochrome works its magic and some disagree with the whole theory. But at least that little map in the eye created by starlight and quantum mechanics satisfies my curiosity for now. If you’d like a somewhat what more detailed description, I recommend Chapter Two of Weidensaul’s book, A World on the Wing.

Eating and Sleeping,: How Do They Survive Along the Way?

Eating Strategies

Eating on migrations varies according to what and how a bird eats. Most migrating birds depend on trusted stopover sites for food and rest. Allen Chartier wrote that “Migrating warblers, sparrows, and thrushes migrate at night, and put on fat to fly 200+ miles each night…” to their next stop. Eastern Kingbirds (Tyrannus tyrannus) and Barn Swallows (Hirundo rustica) migrate to Michigan from deep in South America during daylight hours, in order to gobble up flying insects while on the wing as well as at known rest stops.

The Eastern Kingbird gulps down insects in flight on its way to us from the Amazon.

Amazingly, some birds in other regions of the world fly nonstop for multiple days and nights without eating at all! Weidensaul describes the Bar-tailed Godwit’s “7,200-mile nonstop flight each autumn from western Alaska to New Zealand, a journey that takes them eight or nine days of uninterrupted flight — the longest nonstop migration known.” They are an impressive example of “jettisoning” organs and living on fat. I’m really glad I’m not a godwit – but I am impressed by them!

Drinking in Flight

Birds don’t sweat but they do lose moisture through breathing and excreting. That may account for so many birds migrating at night when the air is cooler and more humid, according to Weidensaul. Of course they look for freshwater wetlands as a basic source of drinking water. But on long ocean or other nonstop flights, for instance, research shows that they can still maintain a healthy amount of moisture by extracting water from their beefed-up muscles and organs while in flight.

Sleeping on the Wing

Most migrating birds do their journeys in stages, resting during the day or night depending on when they travel. Weidensaul reports that “For migratory songbirds, like White-throated Sparrows and Hermit Thrushes (Catharus guttatus,) the onset of migration seasons … decreases the amount of time they sleep by two-thirds, even in captivity, and well before they start migration. They may compensate by taking micronaps during the day.”

White-throated Sparrows ((*Zonotrichia albicollis*) breed from northern Michigan all the way to Hudson’s Bay but they winter from here to Florida, slipping in naps at stopovers on the way.

Mallards (Anas platyrhynchos) have evolved to use unihemispheric sleep, a condition in which only half the brain sleeps at a time and one eye stays open. Neils Rattenborg directs sleep research at Germany’s Max Planck Institute and his team’s work centers around birds. According to an article from the Max Planck Society, Rattenborg documented that “in a group of sleeping ducks, those [Mallards] sitting at the edge kept their outwardly directed eye open and the corresponding brain hemisphere remained awake. The birds can thereby rest a part of their brain while keeping an eye out for potential predators.” I’m on the lookout for that phenomenon!

Paul Birtwhistle caught this lovely male Mallard feeding. But researchers have learned that while in flocks, Mallards can have unihemispheric sleeping, with one eye open and one half of the brain awake while the other half sleeps!

By outfitting birds Great Frigatebirds (Fregata minor) near the Galapagos Islands with tiny transmitters, Rattenborg also discovered something even more important about sleep. It seems these large birds take repeated unihemispheric naps averaging about 12 seconds long while foraging at sea for six days or more. Sometimes these birds’ entire brains slept while slowly gliding up or down in thermals! Talk about power napping, eh?

What Can We Humans Do to Make Life Easier for Migrating Birds?

Clearly, we’ve created big challenges for migrating birds, despite their amazing adaptations over the eons. So here are just a few of those difficulties and how we might help our beautiful migrating neighbors.

Light Pollution: Birds need a clear view of the night sky even more than we do. (Don’t you miss seeing a sky filled with stars?) So we can turn off outside lights (at home and in workplaces), make the light bulbs yellow or red instead of white, or install shades on outdoor lights that direct the light downward. Inside, we can close curtains or shades where a light is near a window in the evening during migration season. It all helps.
Reflective glass like picture windows: Birds that crash into windows may fly off but they often do so with concussions. Check out this link for options for preventing bird strikes.
Cats: Keep our beloved felines indoors. To quote Cornell Lab of Ornithology on this subject, “These are non-native predators that, even using conservative estimates, kill 1.3–4 billion birds and 6.3–22.3 billion mammals each year in the U.S. alone. Exhausted migratory birds and fledglings are particularly at risk.
Habitat Loss: Restore natural areas and plant native plants at home. Birds count on finding the adult insects, caterpillars, and seeds that make up their diet when they arrive at a stopover or their final destination. If that land is covered by concrete or invaded by non-native plants that don’t provide the nutrition or cover they need, birds suffer along with the rest of the creatures in that habitat.
Climate Change: Actively, drastically and quickly reduce our use of fossil fuels. Climate disruption effects migratory birds in so many ways. But here are at least two important ones. It causes more severe weather events which vulnerable migrators must negotiate over long distances. Also, insects and plants initiate hatching or blooming by ground temperature; as the ground warms earlier, overwintering insects hatch earlier, plants mature more quickly. Birds, however, initiate migration by the position of the sun and the length of daylight. As a result, tired migrators may arrive in the spring unable to find the insects, nectar or pollen on which they depend. Want evidence? Look here!

Birds Do It, Bees Do It, Even Whales in the Seas Do It … Let’s Do It. Let’s Start to Adapt…

*A sky full of Broadwinged Hawks (Buteo platypterus) at the Hawkfest in 2018 at Holiday Beach near Windsor, Ontario*.

Obviously, we humans need to adapt just like the migrators have – but a lot faster! We don’t have thousands of years for evolution to re-engineer our bodies and nature itself to cope with the new climate we’re creating with fossil fuels. No miracles of transforming digestive systems, cryptochrome maps in our eyes or unihemispheric sleep are on our immediate horizon. Nature already gave us our adaptive tools – our brains and our will. We already know much of what is needed; the trick is, do we find the collective will as a species to do it in time? The changes we need to make are significant, but not insurmountable. Nature is already warning us with tornadoes, floods, droughts, melting glaciers. It’s insisting “You can do this! Use the adaptation tools between your ears that you were blessed with and save us all!” I certainly hope more humans heed that desperate call – and soon!

A Bevy of Migrators Discover the New Wetlands at Stony Creek Ravine Nature Park

April 29, 2020April 29, 2020 / Cam Mannino / 2 Comments

Sandhill Cranes (Antigone canadensis) are a common sight this spring at Stony Creek Ravine Nature Park

While I spent late March and early April scouting out Watershed Ridge Park, the migrating birds – and ducks especially – discovered the sparkling new wetlands at the 208 acre expansion of Stony Creek Ravine Nature Park. As part of this park’s restoration, the tiles that had drained the field while under agriculture were broken. Water began to naturally rise to the surface, recreating the wetlands that once acted as a refuge for wildlife. (For a brief description of this process, see an earlier blog on this park.) So this spring, weary migrators of all kinds began making the most of this new place to rest and forage. Some will spend the summer here raising young. Others relax for a few days and then head north on a strong south wind.

So this blog will be a bit different than others. Thanks to Dr. Ben VanderWeide, our township Stewardship Manager and Ruth Glass, a local expert birder of many years, I received a copious list of the ducks and other migrators that the two of them have already seen at Stony Creek Ravine Nature Park this spring before I made my visits there. Though they watch and appreciate birds, they rarely take photos of them.

Some photos and all text
by Cam Mannino

A fine local photographer, Joan Bonin, who frequents this park occasionally, was kind enough to share some of her impressive photos with me. And I’ve supplemented my recent photos and hers with photos from the generous photographers at iNaturalist.org. So now, thanks to all of those helpers, I can share some of the wild life that’s visiting our newest natural area. The number of beautiful migrators and year ’round birds spotted at this park is dazzling.

[A note: Visiting this new section of Stony Creek Ravine Nature Park is difficult right now, because there’s no parking lot and not much in the way of trails, just tire tracks encircling the fenced enclosure that contains the wetlands within the conservation easement held by the Michigan Department of Environment, Great Lakes, and Energy (EGLE, formerly DEQ.) But the Parks and Recreation Commission hopes to have a parking lot and some trails mowed by this summer. Meanwhile, consider exploring the original 60 acres that features the ravine itself and is accessible at the end of Knob Creek Drive. And if you visit the east expansion, please stay back from the wetlands so that you don’t flush the migrating waterfowl and shorebirds. We’ll let you know when this larger part of park is ready for prime time!]

Restore the Wetlands and They Will Come!

One of the large ponds that formed last autumn at Stony Creek Ravine when the drainage tiles installed years ago were crushed and the water rose again naturally.

It gladdens my heart to know that weary migrating ducks and shorebirds are gliding down from pale, spring skies to settle on these pools. Here are a few that Ben, Joan and Ruth saw. What a collection of special ducks!

American Wigeons floating in a restored wetland at Stony Creek Ravine Park.

The ducks floating inside the conservation easement in the photo above are American Wigeons (Mareca americana). Wigeons are dabbling ducks, as are all the ducks seen at the huge new expanse of Stony Creek Ravine this spring. I imagine that ducks must be able to gauge water depth from the air since we’ve yet to see any diving ducks, which require deeper water. Dabblers tip up, tails in the air, to forage beneath the water for grasses, mollusks, small crustaceans and insects. Unlike diving ducks, dabblers have legs positioned forward, which allows them to waddle and forage on the muddy edge and sometimes on dry land. The legs of diving ducks are positioned farther back on their bodies to provide more thrust for diving, which means that walking on land is awkward at best for them.

American Wigeons have a short bill so they can pick grains off terrestrial plants as well as aquatic ones. Here’s a closeup shot from BJ Stacey at iNaturalist. Pretty jazzy green eye patch, eh? And I like the white bill and crown, which the Cornell Lab of Ornithology says is where they got the nickname “baldpate.” Hope I can remember that for ID purposes!

Ben alerted me to the presence of Green-winged Teal (Anas crecca) in the newly restored wetlands, but though I’ve visited the park several times, I’ve missed them! The bills of Green-winged Teals are edged with comb-like structures called lamellae. By dipping their beaks in the water or wet mud, they can strain out tadpoles, mollusks, crustaceans and such. Both Ben and Ruth spotted 14-16 of these small ducks in the easement ponds at various times this April.

It’s not surprising that a duck with the Latin genus name “Spatula” has a huge spoon-shaped bill! Look at the size of that bill on the Northern Shoveler (Spatula clypeata) below! They feed by swinging it from side to side in shallow water to sieve out creatures from the shallows. The male’s bill is black and the female’s orange. These migrators don’t stick around Michigan for the summer. Maps at the Cornell Lab show them heading northwest to breed in western Canada and Alaska or northeast to breed as far north as Maine or New Brunswick. Northern Shovelers may move south for the winter, but prefer cooler summers when raising young.

Blue-winged Teal (Anas discors) are tiny ducks that make long migrations. Cornell Lab of Ornithology says they spend the winter either in the Caribbean, a likely destination for our Michigan population, or Central and South America for western populations. They usually arrive late in the spring and leave in early fall; Ruth saw some in mid-April at Stony Creek Ravine Nature Park. Blue-winged Teal breed and rear their young in Michigan summers. The male’s white “paint stripe” behind the bill will be a field mark I’ll look for in the future, as well as sky-blue wing patches beneath their wings when they rise into the air. (Photo by Jaden at iNaturalist.org)

Champion bird spotter Ruth Glass also saw Gadwall (Mareca strepera) and American Black Ducks (Anas rubripes) among the flotillas at Stony Creek Ravine. Gadwall may escape notice from a distance, mistaken for your average brown female duck. But look at the beautifully intricate patterning on its breast and flank in the photo below! Cornell Lab reports that these sweet-looking ducks occasionally “snatch food from diving ducks as they surface.” Sneaky little ducks! They’ll head to northern Canada to breed. Glad they took some R&R with us!

One of the ducks that Ruth Glass saw was not a migrator American Black Ducks (Anas rubripes), according to the Cornell Lab, live here year ’round, but they are shy ducks and often mistaken for female mallards. They actually hybridize with Mallards so some have green patches on their heads. Hope I recognize them if I see some this summer!

Ruth and Ben finally spotted some shore birds in the conservation easement wetlands as well. Lesser Yellowlegs (Tringa flavipes) love flooded fields so the shallow ponds are perfect for them. The feathers of this shorebird were fashionable in the 19th century so their numbers declined. They rebounded when hunting them was outlawed in the US and Canada in the early 20th century. Sadly though, they are in decline again because of the disappearance of wetlands. So hooray for Oakland Township’s Land Preservation Fund and the Natural Resources Trust Fund for enabling Parks and Recreation to acquire and protect this habitat that is so important to these birds!

Cornell Lab says that the Greater Yellowlegs (Tringa melanoleuca) is known for its strident alarm calls and will perch high in trees to keep a sharp eye out for nest predators. They migrate from Central America or the Caribbean to the boreal wetlands of northern Canada in order to breed. Its beak looks about as long as its legs! Other field marks include a longer, slightly upturned bill for foraging in deeper water and barring on the flanks that go much farther toward the tail. Pretty subtle differences, aren’t they?

After having failed to see these two Yellowlegs several times at the park, I finally saw a lone one stalking around one of the shallow ponds near Snell Road and took a long distance shot through the fence. Ben and Ruth both guess that it’s a Greater Yellowlegs. It’s easier to judge the two types of Yellowlegs when they are wading around together and the differences in their bill size, barring on their flanks and overall body bulk are more apparent.

And of course, the nattily-dressed Killdeer, a plover who likes a bit of mud at its feet, has taken up residence within the wetlands as well. Since these birds simply scratch out a depression in the soil to lay their eggs, the sparsely vegetated soil of the wetlands provides great habitat. I took this photo between the fence wires and the Killdeer with its large orange eyes paid me no mind.

Killdeers may be happy to nest inside the protection of the conservation fence near the water.

Ruth Glass’ Rare Sighting

Ruth Glass reported a rare bird in Stony Creek Ravine Park this spring – the Krider’s Red-tailed Hawk (Buteo jamaicensis kriderii). Some experts consider it a sub-species of the Red-tailed Hawk; the Cornell Lab of Ornithology and other experts identify it as a color morph of that more common hawk. Whatever, it is rare to see a Krider’s this far east in the United States! Ruth described its normal territory for me. “Krider’s breed on the northern Great Plains of Alaska and northwestern Canada, and winter on the southern Great Plains south to the Gulf Coast, and east into the Mississippi River Valley.” She observed it through her scope for part of an afternoon, but hasn’t seen it since, as it no doubt headed north. What a magnificent and lucky sighting! Here’s a closeup of a Krider’s by an iNaturalist photographer; Ruth said that it’s in very much the same pose and background as the one she saw.

I saw two of our more common Red-tailed Hawks (Buteo jamaicensis) riding a thermal high in the air on a sunny morning at the park. Bathed in the bright sunlight, one of them flew to the field where I was walking and hung overhead, as if it were scoping me out. Glad I’m not a mouse or a chipmunk! Note its brown belly-band and brown head, unlike the Krider’s Red-tailed Hawk above.

“Snow Birds” of the Fields Also Find Their Way Here.

Stony Creek Ravine Nature Park also hosts a wide variety of upland birds which, like human “snow birds,” leave us behind in the autumn and return each spring. Ruth spotted a pair of American Kestrels (Falco sparverius) hunting from atop the fence posts at the park. One afternoon, a monumental chase occurred in which one kestrel grabbed a vole in its talons and the other screamed as it chased its compatriot over the fields trying to snatch it away. Wish I had seen that. Glad Ruth did!

The Brown Thrasher (Toxostoma rufum) also dropped in at Stony Creek Ravine Park. Ruth loves these birds as much as I do. As she says, “They are such a fun bird! As a close cousin of the Mockingbird, the strangest noises come out of them, including: cell phone beeps and rings, car alarms, sirens, scolding noises, many other birds’ songs, etc.” She took a lovely photo of one through her scope at Stony Creek Ravine Park.

Ruth can identify minor differences between sparrows – and their songs! This month at Stony Creek Ravine, she came across two that are rare sightings for me. I’ve never identified the Vesper Sparrow (Pooecetes gramineus). Though it can be heard in the early morning, its name refers to its evensong at twilight. Looking through binoculars, the field marks for this little sparrow are a thin eye ring and a tiny chocolate-colored patch at the top of its wing.

The Savannah Sparrow (Passerculus sandwichensis) loves grassy meadows, the denser the better; they build their nests on the ground amid deep thatch left by last year’s stems. I wonder if the one Ruth saw a few weeks ago will nest at Stony Creek Ravine; a lot of the land was cleared to create the conservation area. According to Cornell Lab of Ornithology, Savannah Sparrows are very common – but I’ve only seen this striped sparrow with the yellow patch around its eye twice. Here’s my photo from Draper Twin Lake Park in 2018.

A field mark for the Savannah Sparrow is the yellow patch in front of the eye.

One Sunday afternoon, my husband and I watched the flight of a returning Great Blue Heron (Ardea herodias) who settled onto a tree limb. Herons normally nest in rookeries so I’ve no idea where this one will settle into its communal nursery. I was just glad that it had a good long look at Stony Creek Ravine from its perch at the edge of the trees north of the wetland enclosure. Amazing how such a large bird can look so tiny against that lovely dark woods!

Ruth arrived high on the Outlook Point between the restored wetlands at dusk to see the mating flight of the American Woodcock (Scolopax minor). She tells me she’s seen three of these “timberdoodles!” I finally got a good look at one last year when Ben held his annual Earth Day Woodcock event, sadly cancelled this year due to the need for social distancing. At dusk, this oddly-shaped bird makes a buzzing beep, sounding a bit like the cartoon Road Runner. Then it sails high up in the darkening sky, spirals down and lands right where it took off. Quite a courtship ritual! I’ve scared them up right from under my feet at least three times in various parks, but with no chance for a photo. Fortunately iNaturalist photographer Ty Smith was luckier than I was.

My trips to Stony Creek Ravine Nature Park this month have given me a chance to welcome back a couple of my favorite sparrows. The Field Sparrow (Spizella pusilla) with its pinkish beak and feet showed up for me about 10 days ago. The males sing their bouncing ball song all over the park right now. Maybe the shy, quiet one that my camera caught (left below)was a female. The male Song Sparrow (Melospiza melodia) tirelessly repeated his courting song that ends in a quick buzz or trill. And as always, he accommodated me by sitting on a perch in the open and ignoring my presence completely. [Click on photos to enlarge; hover cursor for captions.]

Look for the pinkish beak and legs to identify a Field Sparrow.

The male Song Sparrow throws back his head back and sings!

Here’s just a sampling of the variety of birds that the four of us – Ben, Ruth, Joan and I – have enjoyed in Stony Creek Ravine Nature Park this month. Such abundance – and I’m sure we’ve not yet seen all there is to see!

With Apologies to John Donne: No Creature is an Island…

Old Oak at Stony Creek Ravine Nature Park

I must admit that at first it felt a bit odd using so many photos by other people in this blog. Usually the observations and photos are mostly mine. But it’s occurred to me that it’s somehow fitting to be supported by others’ efforts in this season and during this hair-raising global pandemic. In early spring, the bird world is busy with all kinds of cooperation. Migrating birds often travel in large flocks for safety and to find the habitats they need. Mating birds work cooperatively in building and protecting nests. And in the human sphere, we’ve become conscious during the virus outbreak of how much we depend on the assistance of others – all the workers in hospitals, grocery stores, police and fire departments, pharmacies, research labs as well as teachers, journalists and parents working from home. So perhaps it’s appropriate that the observant eyes and photography skills of others are central in this week’s blog. My thanks to Ruth Glass, Dr. Ben VanderWeide, Joan Bonin and all the generous photographers who share their work on iNaturalist. And my gratitude, too, to the Oakland Township Parks and Recreation Commissioners and staff who worked for years to preserve this special natural area for the benefit of all of us – and more importantly for the wildlife and plant life that sustain us every day in so many ways.

And now to John Donne’s meditation on community written in 17th century England, another time and place of plagues:

“No man is an island,
Entire of itself,
Every man is a piece of the continent,
A part of the main.
If a clod be washed away by the sea,
Europe is the less.
As well as if a promontory were.
As well as if a manor of thy friend’s
Or of thine own were:
Any man’s death diminishes me,
Because I am involved in mankind,
And therefore never send to know for whom the bell tolls;
It tolls for thee.”

John Donne

Gallagher Creek Park: A Time of Transitions Created by Caring Humans and by Nature Itself

June 25, 2019July 2, 2019 / Cam Mannino / Leave a comment

: Children and parents enjoying the play area at Gallagher Creek

Little, busy Gallagher Creek Park has gone through some big changes in the last few years. The Oakland Township Parks and Recreation Commission made a commitment to provide this densely populated area of the township with a playground for children. And they made it happen very quickly! Meanwhile, Dr. Ben VanderWeide, the township Stewardship Manager, set in motion a plan to eliminate large stands of non-native shrubs and begin restoring the fields that surround the new playground. This spring, he and his crew spent long hours creating and planting an extensive set of native gardens.

So I’ve enjoyed several happy outings at this little green park from late April to late June, observing both the exciting changes initiated by human effort and nature’s annual, sometimes less noticed, transition from spring to summer. Glad you’re here to share both of them with me.

The People Factor: From an Old Farm Field to a Playground Surrounded by Beauty

In the spring of 2015, the restoration of native habitat at Gallagher Creek began with a prescribed burn handled by contractors and supervised by Dr. Ben. Having done a plant survey, he had found many native plants struggling to grow amongst invasives. So in 2015, before the Parks Commission began to consider playground plans, Ben set about removing large stands of aggressive shrubs from the eastern sections of Gallagher Creek. In the early winter of 2016, he was able to begin planting native seed, using budgeted Land Preservation millage funds and a prairie restoration grant from the US Fish and Wildlife Service – Partners for Fish and Wildlife program. (Click on photos to enlarge; hover cursor for captions.)

From 2016 to 2019, the Parks and Recreation Commissioners and Director Mindy Milos-Dale set about making the playground area a priority project. A professional architect from Professional Engineering Associates (PEA) worked with the Parks Commission and staff to develop a design for the playground, picnic pavilion, and paths that would harmonize with the natural environment. The Township Board’s Safety Paths and Trails Committee worked with dedication to complete the northern paved trail along Silverbell Road that leads into the park and LJ Construction did an excellent job of putting it all together. Now it’s easier and safer for families to reach Gallagher Creek Park from surrounding neighborhoods. And the stewardship crew, volunteers of all ages, and Dr. Ben set out to surround the playground with an educational garden that can familiarize both children and their parents with lovely plants that are native to our area.

All of the work came to fruition this May when the park was dedicated and the gardens completed.

Nature Begins its Transition at Gallagher Creek

The paths that lead out of the native gardens create a transition from the playground to the natural areas that surround the slides and swings. Right now, the only trail beyond the playground leads to a platform near the creek, but more are planned. So knees cocked high, I waded through the carpet of tall grass and flowers, exploring, watching a wet, cold, spring make the transformation into early summer.

A Cold, Wet Spring at Gallagher Creek: Wildflowers Emerge, the Birds are Fewer than Previous Years, and Insects Not Yet Active

May was wet! Gallagher Creek, normally shallow and wandering slowly through tall grass, flooded over into pools beneath the sheltering willows. Instead of whispering, it burbled along it path toward Paint Creek. The cool temperatures and moisture were perfect for some plants.

The most spectacular spring wildflower was the Yellow Lady Slipper (Cypripedium parviflorum) tucked in near the old stump left of the platform at the creek. The long purple ribbons on these yellow dancing shoes suit this wildflower’s name just perfectly!

Mayapples (Podophyllum peltatum) erupted from the soil in time to live up to their name, too. They formed a circular carpet out in the eastern field, where Ben had cleared a dense stand of shrubs in a previous year. Mayapples are more commonly seen in wooded areas but this colony of them seems quite happy to be surrounded by tall grass.

Their modest little flowers, which emerge from little “green apple” buds, droop shyly beneath the leaves.

Wild Strawberry flowers (Fragaria virginiana) lay hidden in the grass all over the park. Their berries will provide a tasty treat for all kinds of animals who always get to these berries before I do!

Where Gallagher Creek had flooded , it had left standing water far out in the eastern field. And some little rivulets flow the other way, toward the creek from the marsh near Silverbell Road. So I was glad I had waterproof hiking shoes. All along the creek in May, golden splashes of Swamp Buttercup (Ranunculus hispidus) shone like little suns from the wet grass. I’ve never seen as many here as I’ve seen this year.

When Ben cleared the shrubs, he saved a lovely Nannyberry bush (Viburnum lentago) that can now stand out in the landscape. According to the website Illinoiswildflowers.info, this graceful native shrub or small tree later produces juicy, sweet, purplish fruits that many birds love, including Ruffed Grouse, Northern Bobwhite, Ring-necked Pheasant, Northern Flicker, Gray Catbird, American Robin, Hermit Thrush, Eastern Bluebird, Cedar Waxwing, Rose-breasted Grosbeak, and Purple Finch. It’s also a popular nesting shrub for birds. Sounds like a good one for my yard!

Oak trees are “monoecious,” meaning they have both male and female flowers on the same tree. The male flowers look like little bright green balls on the long, elegant catkins and the female flowers, which become the acorns, are inconspicuous little blossoms on the same branch. The female flowers are pollinated by the wind, which means a lot of us around here are sneezing in May! And once the male flowers open and shed their pollen, they fall to the ground. Here are the male flowers on an oak at Gallagher Creek Park (maybe black oak, Quercus velutina).

Just a couple of birds kept me company at Gallagher Creek Park in late April and May. I mentioned in the blog earlier this month that a birder friend sent me a photo of a Killdeer (Charadrius vociferus) standing over her eggs in the shallow nest she’d scraped in the bare earth. The eggs, however, disappeared without my birder friend or me ever spotting the fledglings. Killdeer nests are awfully vulnerable to snakes, raccoons, coyotes and of course, careless humans! But I’ve learned that the adults can lead newborns to safer territory with water and food on the day they hatch from their eggs. They’re born ready to go. So maybe there are fledglings somewhere on the property being cared for by the male while the female starts a new nest. I hope so.

Last year, the air over the park was filled with swooping and diving Tree Swallows (Tachycineta bicolor). This year, I’ve only seen one or two. It may be that the busy playground has encouraged them to settle elsewhere. Here’s a photo of one high in a tree at Gallagher Creek Park about two years ago, and one on the wing, scooping insects out of the air in the wetland area on the far side of the creek as I’ve seen them doing this year.

As Summer Tentatively Arrived More Birds and Lots of Crazy Insects!

Getting to Know a Killdeer, plus Other Avian Visitors

In June, I thought perhaps I was repeatedly seeing the Killdeer that my birding friend had introduced me to in late April. By June 1, the adult Killdeer had abandoned its first nest and seemed to be striking up a friendship with a local American Robin (Turdus migratorius). The killdeer appears to be the female, since the only other adult killdeer around is usually flying in circles making its piercing territorial call which is the male’s way of protecting his mate’s territory. (No wonder the second part of the Killdeer’s scientific name is “vociferous”!) The Robin may have been a female as well, since its head is not as dark as most males. On that June 1 afternoon, these two birds of different species hung out together in a native bed near the pavilion that hadn’t yet been planted. It was surprising to me that the two of them seemed so relaxed in each other’s presence – especially since killdeer are usually quite excitable. I liked to imagine that perhaps the smaller bird found the Robin’s stolid presence reassuring – or maybe that they were silently commiserating over the difficulties of nesting and raising young!

: The Killdeer sat calmly within the unplanted garden and the Robin kept it company.

: After several minutes, the Killdeer stood up close to the Robin, who calmly looked off into the distance.

: And then the Killdeer bobbed away a few steps and paused.

A week later on June 8, the Killdeer was bobbing along among the newly planted garden where it had visited with the Robin, calling now and then.

Six days later on June 14, Ben texted that he’d just seen another killdeer nest with four eggs in it. When I went on my own, I couldn’t find it; their nests are notorious for being well camouflaged! A day later, sharp-eyed Ben texted again to say he’d seen a hatchling coming out one of the eggs! And he sent me this wonderful photo! Be sure to notice the long beak on this youngster.

My husband and I hurried to the park. At first we only saw the female doing a distraction maneuver near the nest location that Ben had described. She huddled down in the grass and stretched her wings up vertically, spread her tail and fluttered, trying to draw our attention. Killdeer females do this when possible predators approach their young. They want predators to think they are starting a new nest. “Don’t look there! Look over here!”

This time we saw the baby bird, probably just half an hour out of its egg. We wanted to keep our distance to avoid any further distress for either the fledgling or its mother so no photo. But while we watched, this tiny bird struggled to its feet for a few seconds, then flopped on the ground and fluttered forward a little on its tiny wings. By a few repetitions of this arduous process, it got away from the exposed nest, the eggs and the hot sun and hid under some grass. What a little survivor! We walked away.

That evening, I learned the following from A Guide to Bird Behavior, Vol. II by Donald W. and Lillian Q. Stokes: “Once the chicks have hatched, the parents lead them gradually to areas with abundant food and some cover…On the first day, the chicks may move up to 120 feet from the nests…Brooding [covering the bird with adult’s body] by one or both parents occurs frequently during the first few days and, of course, during the nights.” I felt reassured, though I’ve not seen the fledgling since it hatched. Here’s a little Killdeer in a photo taken by iNaturalist.org photographer, Steven Mlodinow. Definitely “aaawww” worthy, I’d say. Hope someday I get to see one on its feet like this!

The Robin, by the way, may have been staring toward the pavilion because she was contemplating a nest there. Ben reported two adult Robins calmly ignoring humans below as they zipped back and forth bringing food to their young in the rafters of the pavilion. When I visited on June 14, I saw two Robin hatchlings who still needed to grow into their beaks a bit before leaving the nest. Unlike hatchling Killdeers who leave the nest within minutes, the Robin nestlings can spend almost two weeks in their nest.

On each visit over the six weeks, I kept hearing the “witchedy, witchedy” calls of the tiny, masked Common Yellowthroat (Geothlypis trichas). Each time, though, the calls seemed to be coming from the wetland on the far side of the creek. But last week, on June 19, I finally spotted one high atop a snag near the marsh along Silverbell Road.

On that last visit, I also heard a Song Sparrow (Melospiza melodia) trilling its melody and finally spotted it high on a bare limb. It looked as though it were studying the marsh for insects before singing another “verse.”

A few minutes later, I looked up from a flower to see a Great Egret (Ardea alba) soaring away from the creek and across the marsh. It was gone before I could raise the camera to my eye. So here’s a flying Egret photo taken at Bear Creek marsh a few years ago with a possible mate in the distance. I hope the flying egret nests near Gallagher Creek this year.

Gallagher Creek’s Wild and Weird June Insects

The natural areas at Gallagher Creek Park bloomed with a few more wildflowers in June. And that prompted visits by a variety of insects. Some I wrote about last week when I reported on native pollinators – bumblebees, sweat bees, leafcutter bees and hoverflies. This week get ready for some hair-raising stories! These insects are colorful and fascinating but come with some pretty fierce behavior!

Thanks to very kind assistance from Dr. Gary Parsons, an entomologist from Michigan State University, I now know that an insect I saw last week is a female Feather-legged Fly, specifically Trichopoda pennipes. These insects mimic wasps. With their feathery jodpurs, they sip on nectar, spreading some pollen as they buzz from flower to flower. Their genus also has the unpleasant distinction of laying its eggs in or on other insects. Once they hatch they eat the host! Yuck. According to Dr. Parsons, though, they may play a role in controlling an invasive stink bug because of their parasitic habits. Great looking little critter with a grim reproductive strategy, eh? (Note the two tiny Hoverflies (genus Syrphidae) mating on these Yarrow blossoms in the background.)

Speaking of Yarrow (Achillea millefolium), the fields at Gallagher are filled with this well-known native plant – and insects are making the most of them! Below, a potential victim of the Feather-legged Fly has come up with a snazzy defense. An insect group called Froghoppers (superfamily Cercopoidea) has a nymph stage that we commonly call Spittlebugs. To protect itself from predators, the nymph pierces the plant stem, feeds on its sap (doing no serious harm) and then excretes a bitter-tasting foam around itself. That keeps the nymph moist, insulates it from cold, and hides it from view so it can safely metamorphose within its bubbles. This spittlebug seems to have found an exceptionally safe spot beneath an umbrella of Yarrow buds.

Yarrow also hosted a very impressive arachnid. The long legs stretching down this stalk belong to a Daddylonglegs, also known as a Harvestman (order Opiliones). Unlike other arachnids, their body segments (cephalothorax and abdomen) are fused together and they have two tiny eyes on top of their heads instead of up to eight for spiders. Quite a specimen, isn’t it?

A lovely plant with the oddly descriptive name of Hairy Beard-tongue (Penstemon hirsutus) played host to an Eastern Carpenter Bee (Xylocopa virginica ) this week. Unlike the Bumblebee which it resembles, it doesn’t have a long tongue to reach into these delicate lavender tubes for nectar. Sometimes the Carpenter Bee has to slit the petals open to reach the pollen in narrow blossoms. I wonder if that’s why this bee solved the problem by choosing the smaller, shallower flowers?

An Eastern Pondhawk dragonfly (Erythemis simplicollis) rested among the greenery in the eastern meadow. According to the “Bug Lady” at the University of Wisconsin Milwaukee Field Station, the white tip of her abdomen means she’s a female and they can lay up to 900 eggs per day! Most of the eggs and larvae, of course, will get eaten by fish and frogs. Dragonflies are flying predators. By snagging other insects from the air, they keep the habitat in balance. And they are such flying aces!

We need a relief from cool but strange insects, right? So let’s end with a second, closer look at Gallagher’s butterflies, some of which were featured in a slideshow last week. Here’s another look at the gorgeous Red-spotted Purple buttefly (Limenitis arthemis astyanax), this time with the upper (dorsal) view and the equally dramatic lower (ventral) view.

And here’s the tiny Pearl Crescent, this time with its fuzzy face peering over the edge of a leaf as it flitted about the eastern meadow. The matching orange tips on its striped antennae are nice touches, aren’t they?

The Silver-spotted Skipper (Epargyreus clarus) is named after the silver patch on the underside of its wings. Its caterpillars protect themselves from predators by creating a leaf shelter by cutting a flap off the edge of a leaf, folding it over and than fastening it shut with silk!

Gallagher Creek Park’s Colorful Future

Gallagher Creek Park already greets the eye with brightly colored playground equipment and the bright little faces of the children who come each day to enjoy it. And out in the meadow, both native and non-native wildflowers add their beauty to a park visit.

Imagine the color and variety that will greet us when the native gardens come to full bloom in two or three years! Those sturdy native prairie plants in the playground gardens will eventually survive bright sunlight and droughts without much watering because they take the time to grow long roots before fully blooming. Here’s a slideshow of some of those plants as they’ll look when full grown. Maybe they’ll set us dreaming about our own gardens!

Photos of the Week: We Made It! The First Sure Signs of Spring!

March 22, 2019 / Cam Mannino / Leave a comment

Vernal pool thawing at Bear Creek

J.R.R. Tolkien provided the ideal words to describe the in-between season in which we’re suspended right now: “… a morning of pale Spring still clinging to Winter’s chill.” Spring is officially here with the Spring Equinox, but mornings in the prairies and forests of the township can still feel as though we’re caught in the last weak grip of winter.

So this week, I thought I’d be on the lookout for sure signs of spring’s arrival and naturally, once I started looking, they were everywhere!

Birds Herald Longer Days with Song and Some Fancy Posturing

Arriving at Draper Twin Lake Park one cold, gray Sunday, my husband and I heard a very loud, clear rendition of the entire spring song of a Northern Cardinal (Cardinalis cardinalis). (Cardinals have a lot of calls. Listen to the second call listed at this Cornell link – that’s the one we heard.) This fellow seemed confident that he could woo the ladies and establish his territory at the same time with his full-throated singing! Look at that beak!

Male American Goldfinches (Spinus tristis) at our feeder are changing out of their modest winter attire into their breeding feathers. In a month or so, they’ll be bright yellow in the hope of interesting a female with an eye for color. Here’s a male on the bottom right perch of our thistle feeder who started changing his wardrobe in March. Perhaps the female on the bottom left perch will be interested? (The other birds are Pine Siskins (Spinus pinus) who will migrate north before long.)

The male Goldfinch on the bottom right perch is signaling spring by changing into his bright yellow breeding feathers.

The buzzing trill of the Red-winged Blackbird (Agelaius phoeniceus), which is accompanied by raising his red shoulder patches, is a common and beloved sign of spring here in Michigan. But last week I saw a male who was taking display to a whole new level. While calling, he also began awkwardly dancing along a branch, keeping his scarlet “epaulets” raised, occasionally fanning his tail, all in the interest of establishing a territory and showing off for some lucky female. What a guy! (Click through the slide show below to see the progression of his dance!)

Other birds establish dominance over other males with creative use of their necks! Below two newly arrived Common Grackles (Quiscalus quiscula) appear to be trying to “out-snoot” each other with their beaks tilted skyward! I think the one on the right is probably the winner here, don’t you? Or else the one the left is an uninterested female. It’s hard to tell.

Grackles use head tilting to establish dominance over other males.

Mark, a birding friend, told me that the Common Goldeneye (Bucephala clangula) at Stoney Creek Metropark were doing their dramatic neck displays as well. According to Cornell Lab’s All About Birds website, Goldeneyes spend December to April in courtship groups where they form mating pairs by performing a lot of energetic neck movements. The male bends his neck backwards until his head lays on his back and then he snaps it forward, splashing water with his feet at the same time! The female responds by lowering her head and swinging it forward. Pretty dramatic courtship! I wasn’t able to get to the Metropark this week, but a kindly photographer from iNaturalist, who goes by Mike B, allowed us the use of this photo of a male taken near Chicago. These diving ducks are headed to their breeding grounds in northern Canada and Alaska, just south of the Arctic.

Flocks of Birds – Large Ones and Small Ones – Fly Overhead and Forage in Our Parks

The birding group had an exciting Wednesday at Charles Ilsley Park when two huge flocks of Tundra Swans (Cygnus columbianus) flew overhead! Cornell says that these huge, all white swans with black beaks spent the winter on the Atlantic coast and are now headed to the Arctic tundra to build their nests and breed. Aren’t we lucky to be on their flyway?

Another birding friend, Mike Kent, took the photo below, because, wouldn’t you know, that was the day I decided to leave my camera at home!!! Look carefully at Mike’s photo because he caught a fascinating detail. We saw one lone Canada Goose (Branta canadensis) traveling along with this huge flock of swans! You can just see its dark body in the upper left of the photo, third bird down. Hope this adventurous goose doesn’t plan to go all the way to the Arctic with its new-found friends!

That Wednesday was great for seeing big birds at Ilsley Park. Mike also caught for us a nice photo of a family of Sandhill Cranes (Antigone canadensis) who settled at the bottom of a slope to rest and feed. The larger, darker birds to the right are probably the adults, while the two smaller gray ones on the left are probably last year’s young ones.

At Bear Creek Nature Park, smaller flocks were chatting in trees and foraging along the paths. A noisy group of American Robins (Turdus migratorius) were snatching berries from a tree infested with invasive Oriental Bittersweet (Celastrus orbiculatus). Some robins overwinter here and some migrate to southern Ohio and Kentucky. Some move back and forth all winter long. Though these non-native berries attract them during the winter, they unfortunately don’t provide much nutrition for the birds since thawing and freezing makes them very sugary. So migrating, in their case, might be a better choice!

On a path from the playground to the Walnut Lane at Bear Creek Nature Park, I saw my first flock of Song Sparrows (Melospiza melodia). I love to listen to these tuneful birds in the spring, but have never before seen a flock of them in one area, as I did this week. They were “chicken-scratching” by scooting backwards with their feet in a ferocious attempt to get at some food beneath the surface -probably small seeds or insect eggs. The flock was so busy that the ground along the trail looked torn as they scraped their way down to the frozen surface, looking for food.

Buds are Swelling from Bare Branches – a Welcome Sign of Spring’s Arrival

Every year as spring approaches, I watch the Silver Maple (Acer saccharinum) to the right of the deck at Bear Creek’s Center Pond. It’s always one of the first trees to signal spring for me, its robust, red buds hanging gracefully from drooping branches over the water.

The swelling red buds of Silver Maple are an early sign of spring approaching.

A small Shagbark Hickory (Carya ovata) near the pond has just barely thrust its leaf bud from the woody protection it had during the winter (left). In May, it will be a huge glorious bud (center), and in June, the green leaves will unfold into the sunlight (right). (Click photos to enlarge; hover cursor for captions.)

Yes, It’s Muddy…but It’s S’posed to Be, Right?

Sky in a puddle at Bear Creek Nature Park

It’s the end of March. Most of the ice on the surface is gone (at least for the moment!), but the ground is still frozen beneath. So rain and melting snow have nowhere to go. That makes for muddy shoes, smeared pant legs and cars decorated in various shades of brown. But hey, those signs announce that full-fledged, glorious spring is almost here! Birds are beginning to sing, dance, do a bit of neck gymnastics, don spring colors and wing their way north overhead in huge numbers. And trees are slowly waking from their roots, sending sugary sap up through their vascular systems, ripening their leaves for another summer of sun-gathering. All of nature, including us humans, have survived a very challenging, deep-freeze winter. Now’s the time to celebrate just being alive on a mudluscious walk in the pale sunshine of an early spring morning.
