Worried About the Planet? Let’s Make a Difference One Garden at a Time.

It’s admittedly a worrisome time for those of us  who love our small, blue planet. Devastating fires, raging floods, 30 billion fewer birds in the last 50 years, a UN report that 100 million species of plants and animals are at risk of extinction within decades. According to Eduardo Brondizio at Indiana University, half a million species have “insufficient habitat for long-term survival.” Their best hope is restoration of their habitat.

Aha! Now here’s something you and I can do something about! And we can do it without leaving home, or participating in protests or influencing recalcitrant politicians. We can enrich the habitat right beyond our kitchen windows. And it won’t take sacrifice – in fact, it’s rewarding! It won’t take giant sums of money or raising taxes. All it takes, dear kindred spirits, is adding native plants to our gardens and yards – as many as we can plant each year. By doing so, we can make a HUGE difference to the survival of species. Stick with me here. The news keeps getting more hopeful as we move along.

Is Your Yard Full of Non-native Plants?  Mine Is…

I’m betting your garden is a lot like mine – filled with non-native trees, grass, shrubs and flowers that evolved in distant countries.  I’m thinking of common garden plants like Lilacs (Syringa vulgaris) from the Balkans in Southeastern Europe, Forsythia (Forsythia intermedia) from eastern Asia,  or Vinca (Vinca minor) from Europe, Africa and Asia.  Take a short world tour in this slideshow and discover where a few of our most popular garden plants originated. [Use pause button for time to read captions.)

Our non-native, international gardens look lovely;  butterflies sip nectar from the flowers and insects never leave a hole in the leaves.  The turf grass looks like a seamless green carpet if we fertilize it and water it regularly.  So what’s the problem?

Well, in their homelands, our non-native plants were not a problem.  They did just what nature asks plant to do – pass on  the sun’s energy (through photosynthesis) to all the other organisms in their habitat that can’t do that.  In its native Europe, invasive Phragmites (Phragmites australis subspecies australis), for example,  supports over 170 insect species. But not here! Here the invasive, non-native grass crowding every wet roadside supports only 5 species – and it’s been here for centuries!

Burning won’t kill phragmites! Here, we’re using controlled burning to remove dead Phragmites that was treated in fall 2014. We remove dead material in the hope that native plants may emerge.

Problem: Our Gardens are Missing One Essential Feature – Plentiful Caterpillars

Now you may be thinking, “Caterpillars eat holes in leaves! The lack of caterpillars is not a problem!!!” Well, actually, it is. Like me, you’ve probably always thought of your garden or lawn as an artistic or decorative enterprise. And it should be! We all need beauty around us. But nature needs our garden flowers, grasses, shrubs and trees to be productive, as well as beautiful. Our yards also need to nourish creatures large and small who live around us. The sad truth is that  most of our gardens are green, colorful food deserts that leave nature hungry and malnourished. Luckily, we can easily change that!

Insects: “The Little Things that Run the World”

Insects, including butterflies, moths, and many other pollinators keep an ecosystem fed. They really are, as the famous biologist E.O. Wilson said, “the little things that run the world.” An insect’s chubby caterpillars chewing and hunching along a plant stem provide essential food for the whole web of life. Birds stuff them down the scrawny throats of baby birds; caterpillars are soft and filled with the fat and protein nestlings need. Adult birds snag insects from the air, pluck them off the ground, and snatch them from leaves. They even spend winter days probing loose bark looking for frozen insect eggs or caterpillars to get the protein that helps keep their small bodies warm on icy nights.

Without enough caterpillars, birds won’t lay a full clutch of eggs in the spring. Their  young will not be as large and healthy. And they need a lot of them! Chickadees, for example, need 6,000 to 9,000 caterpillars to raise their clutch of nestlings! Caterpillars are simply the most important food source for birds, amphibians, reptiles, fish, and some mammals. Seeds and fruits contribute to food webs too – but caterpillars are essential.

So Why Are Our Yards Missing So Many Caterpillars?

Ninety percent of our native caterpillars, the young of daytime butterflies and the moths who maneuver through the night, are picky eaters! They can only eat plants with which they co-evolved. They are specialists who, over eons, have overcome the chemical defenses of particular native plants and are now adapted to eat them and nothing else. Unfortunately, they aren’t able to switch to what’s available. It would take thousands of years of evolution to make that possible. So if our caterpillars don’t hatch out on a native plant, they generally die of malnutrition before reaching adulthood.

The Monarch butterfly (Danaus plexippus), of course, is the classic example; its caterpillars can eat only one genus – the milkweeds (genus Asclepias).  Monarchs will sip nectar from all kinds of flowers, but their caterpillars need one of the milkweed species for food that will nourish them to adulthood. And 90% of all our insects face the same challenge of finding the native plants their young can eat. Not enough native plants means not enough insects and their caterpillars, which means not enough birds, not enough amphibians –  and on it goes as hunger spreads through a habitat’s food web.

A Beautiful, Simple Solution: Plant More Native Flowers, Grasses, Shrubs and Trees

So many environmental issues are beyond our control. But we can control our yards, our gardens, the fields and woods on our land. And we can turn around the declining numbers of butterflies, pollinators, birds and more by nourishing wildlife around us with beautiful native plants. They come in all kinds of colors and shapes. Some thrive in wet areas, some in dry. Some need the sunshine, some the shade. Some bloom in only one season, some in more than one. Some are even green all winter! Here’s just a tiny, rainbow sampling  to whet your appetite!

Our Gardens and Yards Can Change Gradually, Right?

We don’t need to overhaul our gardens overnight. I plan to just gradually add in more native plants each year. Ideally, our goal is to reach at least 70% native – but any increase in native plants benefits our local habitats. For example, I can’t afford to eliminate the non-native woods of invasive Black Locust (Robinia pseudoacacia) next to our driveway – but I can remove its invasive sprouts wherever I come across one. And maybe year by year, we can remove a bit more of the Vinca and Lily-of -the-Valley that have choked out native woodland flowers on the forest floor. I’m thinking  of removing Locusts that are crowding the few native Wild Black Cherry Trees (Prunus serotina) in the woods and perhaps adding in a few native understory trees to help out the birds and insects.

Dense woods of non-native Black Locust

Three years ago, I started taking on the invasive Garlic Mustard (Alliaria petiolata) that has encircled our yard and infiltrated the woods for years. Pulling them out by the roots is quite easy; my 4-year-old neighbor enjoyed doing it with me! And the reward at our house is that beautiful, native White Snakeroot (Ageratina altissima) now rises out of the earth each autumn wherever I pulled the Garlic Mustard in the spring! (Have a look at the beautiful bank of white blossoms below!) I’m anxious to know what else may be hiding in the seed bank under the forest floor!

If placed in the right environment, native plants are less fussy than non-native plants we usually get from the garden store. They’ve evolved in our ecosystem so they don’t need the regular watering, fertilizing or soil amendments that non-natives usually do. In fact many of our native plants do better in poor soil! Rain generally provides enough water for them, except in severe droughts. You’ll need to experiment to see what works, just as you do with non-native plants. Some will grow more vigorously than you’d like and need to be thinned; consider sharing them with neighbors! Others will need to be moved to a new location. That’s OK! It’s all a learning process, right?

A Word about that Lawn…

Douglas W. Tallamy, author of Bringing Nature Home, a sort of  “bible” for native gardeners, points out that millions of acres in America are covered by our lawns. In fact researchers say that the American lawn covers an area the size of New England! Turf grasses are non-native and require huge amounts of water, chemical fertilizers and herbicides to keep them  green. Mowing them frequently also uses lots of fossil fuel.

Now neither Doug Tallamy nor I are not advocating that you ignore your lawn and let it grow into a fallow field full of invasive plants! What Tallamy and other conservationists are asking is this: Could you do with less grass and plant more native gardens? Could you plant a native White Oak (Quercus alba) in your front yard? (White Oaks can support over 500 different insect species and still look great! Could you put native shrubs along your driveway? Maybe you could plant a more formal native garden in the front with drifts or masses of native plants that love to be planted close together.  (No need for mulch!)

Grass paths could be used to guide you through your landscape; turf grass is great to walk on. If your children play outside (and I fervently hope they do!), leave a play area but surround it with native wildflowers or flowering native shrubs. And where you have slopes or large open areas with plenty of sun, consider taller native grasses like Little Bluestem (Schizachyrium scoparium) or Big Bluestem (Andropogon gerardi) and a variety of sun-loving prairie plants. Native grasses and shrubs provide artistic structure in a garden, but also give caterpillars safe places to spin their chrysalises and cocoons.  The possibilities are endless.

An Inspiration for the Future:  The “Homegrown National Park”

In his newest book,  Nature’s Best Hope, Dr. Tallamy proposes a glorious vision of what a dedicated nation could create for its people and its wildlife. He envisions all of us together creating huge swaths of native habitat by linking our native-growing neighborhoods into a “Homegrown National Park.” Imagine that! Our new national park could be as large as 20 million acres if we all reduced our lawn areas by half. Wow! An audacious idea, but theoretically possible. For the moment though, our goal can simply be to enhance the habitat around our own houses and perhaps eventually a network of houses and neighborhoods full of both life and beauty.

Imagine Your Native Garden as Living Landscape, a Beautiful Habitat Where Nature Thrives

February is a great time for garden dreaming. Envision the possibilities outside your kitchen window. A green path wends it way between native gardens that change with each season. Warm patches of sunlight bring butterflies looking for nectar. Perhaps fledgling bluebirds beg to be fed beneath your native flowering shrub. In the shade of the native tree canopy, migrating birds stop by to sing while looking for caterpillars or to pluck a few berries on their way south for the winter. I’m finding a whole new set of yard dreams myself. I hope you conjure up a few too, and add some natives to your yard this year.

Charles Isley Park: Dressed in the Gold and Black of Late Summer

Do me a favor, would you? Imagine standing in front of a huge meadow full of tall grass and wildflowers dancing in a soft breeze. You can hear crickets and cicadas singing in the deep grass. Now turn your computer’s volume to about half and click on the arrow in the image below. (You’ll hear a little of the wind in the microphone.)

There! That’s a bit of what it’s been like at Charles Ilsley Park in the last few glorious weeks of August.  Goldfinches sing as they swoop in their roller coaster flights across the fields that are burnished with goldenrod. Butterflies, with golden wings fluttering, sip sweet nectar from the giant thistles. And all of this gilded beauty is backed by the sounds of a summer breeze sighing in your ear and the buzz of cicadas and crickets. That’s about as close to pure glory as my life affords.

The Glow Began in July…

The eastern path through the central meadow at Charles Ilsley Park on July 15, 2019

Let’s just say the Black-eyed Susans (Rudbeckia hirta) got magnificently carried away in the central meadow at Ilsley. Perhaps the contractor who planted wild seed last year had a wee bit too much of them in the mix? But I didn’t hear anyone complain when the meadow was literally blanketed in black and gold. By early August, they had browned, leaving behind seeds that will provide nourishment for migrators and winter birds.

Nature Comes Back with a Second Wave of Gold

A female Monarch (Danaus plexippus) stares out at me from a Black-eyed Susan finished off from the intense heat of July. Her wings are a lovely soft gold underneath.

In their place, though not quite as abundant, came a close relative, the buttery yellow Brown-eyed Susans (Rudbeckia triloba). Instead of a single flower on each stem like their black-eyed cousins, these Susans produce branching stems with profuse, but smaller blossoms which create a similar sunny effect.

Brown-eyed Susans emerged just as the Black-eyed Susans faded, though not in quite the same profusion.

Of course, August always brings waves of different Goldenrods to keep the gold coming in late summer. Right now, I commonly see three different ones: the cascades of Canada Goldenrod (Solidago canadensis), Stiff Goldenrod  (Solidago rigida) with its ramrod stems lined with clinging oval leaves and bouquet-like sprays of Grass-leaved Goldenrod (Euthamia graminifolia) which is from a different genus of the Aster family. Later in the month, we’ll begin to see the  upright, lemon yellow plumes of Showy Goldenrod (Solidago speciosa) doing its part to keep the fields golden right into September. (Click on photos to enlarge; hover cursor for captions.)

The Gray-headed/Yellow Coneflowers (Ratibida pinnata) add their droopy charm to the fields too, though their best days are behind them for this season. And the tall spikes of Common Evening Primrose (Oenothera biennis) are topped by gold blossoms that stay open from evening until early morning, and later on cloudy days as well.

I love how native plants host so many insects in an era when the insect world is suffering from plunging numbers all over the planet. Here two False Sunflowers (Heliopsis helianthoides) standing next to each other hosted a Soldier Beetle (Cantharidae family) and the nymph of a Katydid (Tettigoniida family). Have a closer look at the amazing length of the katydid’s antennae by clicking on the right photo. One of the ways you can tell a grasshopper from a katydid is that grasshoppers have much shorter antennae than the very long, fine ones you’ll see on the nymph below.

Out in the far west of the park at the edge of the woods, a tall, striking, yellow flower with very unusual blossoms caught my eye. Dr. Ben VanderWeide, our township Stewardship Manager, identified it for me as Wingstem (Verbesina alternifolia)and indeed, its flat stem had narrow “wings” on either side. Wingstem flower heads cluster at the top of the 3′-8′ stem. Each bloom is actually a flower within a ring of flowers. The “disc florets” in this plant are the tube-shaped flowers that thrust outward from the center of the flower head. What looks like a ring of petals around the central disc is actually a ring of “ray florets” and each of them is an individual flower that has the ability to produce its own seed. In botany, “florets” are individual flowers within a flower head, whereas what we see as individual petals on ray flowers are really three petals fused together. And how about those curly little stigmas that we see whimsically protruding from the ends of the disc florets! What a fun wildflower!

Wingstem is not seen a lot in Michigan, but it’s now growing in two of our parks!

Wingstem has a limited distribution in Michigan, so we’re lucky to have them. These Charles Ilsley Park plants grew from seeds that Ben collected at the township’s Blue Heron Environmental Area, which was the only place he’s seen them in the township. It’s exciting to know that the seeds Ben planted at Ilsley have taken hold, so that we now have two parks in which this unusual native plant has found a home.

Birds Matching the Black and Gold Landscape

Let’s Start with A Goldfinch Saga!

American Goldfinches (Spinus tristis) – Unlike most other birds, Goldfinches start mating around mid- to late-July when the thistles bloom, which is a source for both nesting material and food for them. Once the first broods fledge in early August, most Goldfinches mate a second time.

On August 9, Mike and Joan Kent, birding friends, took a walk at Ilsley and spotted a nest in a thistle.  Joan peeked in and saw 3 eggs. They noticed a lot of Goldfinches nearby and assumed it was probably the nest of one of them. And that was that, until…

On our Wednesday bird walk on August 21, Vinnie Morganti, another member of our bird group, spotted the same nest located within the thorny stems of a tall Bull Thistle (Cirsium vulgare). A Goldfinch’s cup nest  is woven from plants and root fibers and lashed to a bush or plant with spider silk. Then it’s lined with thistle down which makes it close to waterproof inside. A small masterpiece. This pair chose a location which probably deterred predators, though it may have been a bit hard on the parents’ wings while feeding!

Peeking into the nest, I discovered  4 baby birds. Fellow birder, Tom Korb, got a photo of the blind and slightly fuzzy hatchlings by valiantly sticking his cellphone into the thistle above them. Tom and I decided to share monitoring these little birds until they fledged and report our findings to Cornell’s Nestwatch , a citizen science site we use for our township nest boxes.

We bird monitors are trained not to go to a nest more often than every 3 – 5 days. So when I returned to the park the following day, I stood far off looking through a long lens. Imagine my delight when I saw one little head popping up above the nest! I don’t know if it could see the meadow yet. Perhaps it was just enjoying the breeze ruffling its Einstein hairdo!

I came back to monitor on August 24 hoping to get a photo inside the nest despite the thistle’s thorns. I’d brought along the fancy, black leather gloves my mother had given me years ago to wear to  the theater – but here I was using them to reach inside a thistle! I could picture my mom laughing and shaking her head – but the gloves worked beautifully! In the photo, I could see the opened eye of at least one little nestling, though the rest were snoozing in their sturdy nest cup. It appeared that the beige tips of feathers might be emerging from their dark sheaths. We think now that they were about a week old in this photo.  They’d come a long way  from those blind babies in just 3 days!

Three days after we first saw them, their eyes were opening and their yellowish-beige feathers began to emerge from their sheaths. They were about a week old.

At our August 28 bird walk in another park, Mike Kent told us about his wife seeing the nest at Charles Ilsley Park on August 9.  Good news for us monitors, because that allowed us to use the guidelines on the Nestwatch site to estimate the age of the Goldfinch hatchlings more accurately. After the bird walk, I accompanied Tom on his monitoring trip to the Ilsley nest. What a change! Little heads peered up over the nest edge – eyes and beaks open. According to the Donald W. Stokes’ Guide to Bird Behavior (Vol.1), during their first week after hatching, Goldfinch nestlings are quiet but will silently reach up for food if the edge of the nest is tapped. In the second week, these nestlings begin making a lot of noise – but wisely only do so when a parent arrives with food. Tom got a great photo of the bright red mouth of a begging, but silent, youngster!

That day, all the nestlings, now about 11 days old, looked bright and alert, peeking out into the world and fully feathered. The Stokes Guide explained that those white blobs on the nest are fecal sacs, the avian equivalent of soiled diapers. Goldfinch nestlings are quite fastidious. The first week after the young hatch, adults carry the waste sacs away from the nest. But starting in the second week, little goldfinches back up to the edge of the nest and drop these little packages over the side!

A nestling peers at me from the nest at 11 days old, surrounded by the fecal sacs that  it and the others have dropped over the nest edge.

My last turn at monitoring the nest was on August 31 – and the nest was empty. The nestlings had become fledglings. Our estimate is that they fledged on their 12th or 13th day after hatching. The nest was remarkably clean inside (if not outside) which might have meant a healthier, more comfortable environment for the nestlings.  

I could hear a fledgling begging far off in a stand of thistle and through my binoculars, I thought I saw a couple of small birds fluttering among the stems. A female flew in among the thistle, perhaps feeding “our” fledglings from her second brood. A male seemed to be on sentinel duty nearby before he flew off to gather more seed. Off into the world for our Goldfinch fledglings! And the end of our nesting saga.

Hard-working Goldfinch Adults

While the females incubate a second brood, male Goldfinches  are on their own in feeding the first brood – which can be as many as seven fledglings, according to Cornell’s nestwatch.org! Begging calls of first brood youngsters could be heard a week ago as young fledglings pursued their harried parents around the park or called from the treelines to be found. This little Goldfinch fledgling seemed a bit more mellow than the rest.

A goldfinch fledgling watching for its father and no doubt hoping for a meal.

The Goldfinches’ primary food source is thistle seed so I’ve seen males all over the fields with thistle down (pappus) hanging from their beaks. They dig industriously into the seedhead, pull out the down, carefully nibble off the seeds and then let the down fly. Stokes informed me that they feed partially digested seed to their  young, as they also do for the mate during her first week on the nest. Quite a responsibility!

More Gold and Black Birds!

In a bush in the far west meadow, I saw a flash of yellow and took a quick couple of shots as a bird perched for a moment and then flew.  I wasn’t sure what I’d seen. Local birding expert, Ruth Glass, identified it as a female Baltimore Oriole (Icterus galbula.) She told me that by now most of our summer orioles have left for Central or South America with their young, so the one I saw was likely a migrator from further north.

The birding group saw other birds sporting lovely yellow trim. A trio of Cedar Waxwings (Bombycilla cedrorum) perched far above in a bare tree. Through binoculars, two clearly had the yellow bellies and yellow tail bands that identify this handsome bird. Juveniles have a fainter black mask and some brown streaking on the breast, but in this distant photo against a gray sky, it’s hard to tell if any of them were juveniles or adults .

Cedar Waxwings added their bright yellow bellies and yellow-tipped tails to a golden August morning.

Ruth Glass also helped me identify a strange looking dark bird that mystified me. She said she was “95% sure” it was a male Indigo Bunting (Passerina cyanea) molting from his brilliant blue breeding colors  into his mostly brown non-breeding colors which are similar to the female Bunting. This mottled look is common for males during the molt. I would never have guessed! Thank you, Ruth!

Some large dark brown birds also added contrast to all the gold around them. A trio of Turkey Vultures (Cathartes aura) rested on a broken snag near the edge of the center field. Through the trees on my way into the park, I saw one of them spreading its magnificent wings to the sunlight. They do this to warm them, stretch them, or to expose any bacteria on them to air and light.

Around the corner, two other vultures perched on a broken snag. This one made me smile, because it looked as though it was appealing for a little sympathy. I’m afraid vultures don’t get much appreciation, though I think their soaring flight is graceful and the cleanup services they provide are crucial. Really, though, the bird was just preparing to preen.

Another vulture looks like it’s asking for sympathy, but it’s really just starting to preen.

The first vulture suddenly flew straight up in the air and landed rather awkwardly on a branch that was much too short. It fluttered clumsily right, then left, until it finally found its footing. Is it my imagination or are the other two a bit embarrassed by the graceless landing skills of their compatriot? Probably, my imagination….  (Tap arrow to play and to pause for reading captions.)

Butterflies Complement the Color Scheme

This August the huge, dramatic Giant Swallowtail butteflies (Papilio cresphontes) arrived in Charles Ilsley Park in large numbers. One afternoon about two weeks ago, perhaps a dozen of them landed delicately on the large purple blooms of Bull Thistle, or hovered in front of them, extending their long proboscises to sip while avoiding the thorns. I don’t know if this thistle is a favorite plant for these big butterflies or if they were just the biggest blooms with the most nectar when they arrived. They chased each other over the fields, creating a shimmer of gold and black all over the central meadow.

A Giant Swallowtail, one of many at Ilsley in August, sips nectar from a Bull Thistle.

You’ll note that the one above has a few missing pieces on its wings and that the black edges look a bit worn. I compared the very tattered dorsal (upper) side of one I saw on thistle at Charles Ilsley Park in late August with the fine specimen I saw on Bee Balm (Monarda fistulosa) at Stony Creek Ravine Nature Park in late July a couple of years ago. I wondered if the difference in wear and tear was due to feeding among thorny thistles or perhaps just the normal battering big wings take after an extra month of foraging and mating. I’m guessing a bit of both.

These dramatic swallowtails have expanded their range further north since about 2001 when first frosts became more uncommon in September – perhaps an effect of global warming. They lay their eggs on plants that will act as hosts for their larvae, which includes two of our abundant natives, Swamp Milkweed  and the Solidago genus of Goldenrods.

The Eastern Tiger Swallowtail (Papilio glaucus) made its elegant contribution to the black-and-gold meadows. These high-flyers raise 2-3 broods each summer. Their caterpillars spin a remarkable chrysalis that matches dead wood very closely. It’s held in place by a thin string of silk on one end of the chrysalis and a silk pad at the other. That’s where the caterpillar spends the winter. There’s a remarkable photo of a Tiger Swallowtail’s chrysalis at the bottom of this Wikipedia page. Be sure to click on it to enlarge so you can tell where the bark ends and the chrysalis begins! My photo below shows the tiny hairs on the swallowtail’s wings – the closest my camera has ever come to a Tiger Swallowtail, I think.

The blue spots at the bottom of her rather ragged wings tells me that this is a female Tiger Swallowtail. Perhaps sipping at thistles has taken its toll on her as well as the Giant Swallowtails?

Three small Lepidopterans played a role in the color scheme. Like the members of the Swallowtail family (Papilio),  a female Black Swallowtail (Papilio polyxenes) found Bull Thistle a good choice for nectar in this transition time just before the Goldenrods reach their full glory and other fall asters emerge. I admit I appreciate the non-native Bull Thistles more this year, having seen how much sustenance they’re providing after a torrid July brought an earlier end to the bloom of so many wildflowers. A Clouded Sulphur (Colias philodice) paused on the drying leaves of a Queen Anne’s Lace. I’ve wanted to see a chrysalis of these small butterflies ever since I read it described as “yellow with a pink zipper”! No luck yet.  And the Ctenucha Moth (Erebidae family) did a fine job of contrasting its black wings with the yellow Grass-leaved Goldrod.

So much gold!  And I didn’t even include the gold and black bumblebees, wasps and honey bees foraging among this late summer landscape! Such riches, eh?

Late Summer Serenity

Sometimes life does come full circle.  Standing at the edge of the meadows at Charles Ilsley Park with sunlight falling on a fluttering, buzzing,  golden landscape, I could feel the deep sense of calm and quiet that I relished in our township in my childhood. On just such a morning then, I would stand on the sturdy limbs of a rugged old tree overlooking a wild pond or spread my blanket in the short grass near the shore and breathe in the comforting scent of warm earth and grass. I feel so fortunate as an older woman to still experience that certainty of being part of something big and beautiful that nature offers all of us if we take the time. I wish that for you, too.

Postcript: Watch for More Ilsley Photos!

Of course, Charles Ilsley Park offered me much more than gold and black in its rich diversity:  a wet spot in a field suddenly blooming with red and blue wildflowers, a fuzzy brown House Finch fledgling peeking through the greenery,  lavender blossoms emerging from the seedbank where a moist swale was restored, a dramatic Darner dragonfly decorated in a pattern of blue and green and more. So rather than extend this blog, I’ll create a shorter photo blog later this week to fill in the rest of the color palette at Charles Ilsley Park.  Hope you can drop by!

Fellow Travelers: Colorful Companions of the Migrating Warblers

What an explosion of bird life in May! In a matter of a few weeks, the trees, fields, marshes and our yards suddenly are alive with bustle and song. Last week, I shared what I learned about the warblers, some of the  tiniest members of the northern migration.  This week, I thought we’d take a look at some of the other colorful summer visitors who are currently serenading possible mates, toting nesting material around our gardens and fields and darting in and out of our backyard feeders.

This spring seems particularly generous with glorious birds. Up-close visits with a startling variety of color and song all around us in 2019 has made this season quite a special one for me.

The Migrators of the Last Week in April

On April 24, just as the sun was getting low, my husband alerted me to something special right outside the window. I looked up from my book to find myself staring at a rare visitor, the Red-headed Woodpecker (Melanerpes erythrocephalus). Twice over the years, we’d caught a quick glimpse of this impressive bird out in the trees beyond the lawn. But it only paused and moved on. Luckily this bird  returned repeatedly that night, so I finally got calm enough to get a shot through the glass – and wow!

The Red-headed Woodpecker is usually heading north to breed, but this year, quite a few passed through the area!

Since then, others have reported seeing more Red-headed Woodpeckers than usual.  We’re hoping ours may be nesting nearby since it’s returned three or four times after its first visit. Sometimes bird lovers confuse this more unusual bird (for our area) with the year ’round Red-bellied Woodpecker (Melanerpes carolinus) who has a red nape but not a fully red head. Red-headed Woodpeckers have become less common in our area due to habitat loss, but maybe we lucked out this year! (Click on photos to enlarge; hover cursor for captions.)

On April 25, I remembered that the Great Blue Herons (Ardea herodias) were already nesting along the Clinton River trail, so I hurried to see them  before leaves began to obscure the view. Saucer-shaped nests topped many trees in the marsh. One heron stood alone, as if on guard, while multiple females, presumably, arranged their nests or perhaps turned over their large eggs.

That last week in April was what folks used to call a humdinger! A birding friend let me know that she’d seen a killdeer with eggs at Gallagher Creek Park. So later on the 25th, I went searching. You’ll probably find her more quickly in this photo than I did in the park. It took me a while, since she was so well camouflaged!

Play “Find the Killdeer” in this photo. She’s nicely camouflaged.

I got very close before I spotted her. She watched me a few moments but surprised me by trotting over to the rain garden so I could take a picture of her beautiful eggs. Very accommodating, though maybe not the best parenting! I’m hoping at least one fledgling survived, since  Dr. Ben VanderWeide, our township stewardship manager, thought he saw a juvenile there in May. Perhaps the predators had as much trouble spotting the nest as I did!

Early May Brought More Solo Arrivals

On May 1st, the birders at Bear Creek Nature Park watched a female Eastern Phoebe (Sayornis phoebe) busily constructing her nest underneath the roof of a kiosk!  Not a terribly private place, but Phoebes do that sort of thing. She’s not as glamorous as some of the other May arrivals, but I liked her placid expression and the brown suede look of her crown. The Phoebe’s two note song is an easy one for most beginning birders to remember. It does sound a bit like “Feee-beee” though it always sounds a bit more like “Feee-buuuuz” to me.

On May 3, one of my favorite avian vocalists arrived in our woods, the male  Rose-Breasted Grosbeak (Pheucticus ludovicianus). Such a handsome devil! And now, every morning in the dark just before sunrise, I’m treated to his sweet courting melody. I’m guessing he found a mate with it, though the female who arrived four days later had her pick of three males counter-singing while I worked in the yard. What a delightful form of territorial competition, as one male’s song overlaps or quickly follows the song of another!

The male Grosbeak is mellow dude who takes his turn peacefully at the feeder, but competes with other males in song for territory and a mate.
The female had 3 singing males to choose from in our yard. What a trio!

On May 5, my husband Reg and I went in pursuit of the Eastern Meadowlark (Sturnella magna) since members of the birding group had seen them at Wolcott Mill Metropark.  And we found him. This glorious prairie bird sang his own slurry version of their 3-8 note song from atop a willow whose new yellow leaves nicely matched his bright yellow breast. Meadowlarks love to hold forth from high on a wire or exposed branch looking out over a field. I hope our prairie restorations will encourage more of these striking birds to nest in our parks.

On May 2, the male Baltimore Oriole (Icterus galbula) arrived right on schedule at our grape jelly feeder. How can anyone resist this dramatic bird? The first male quickly established his rights to the feeder and now proceeds to whistle his song rather insistently near a window whenever the feeder is empty, which is about 3 times a day!  Or at least that’s how it seems to us. We’re happy to accommodate him and later his mate.

Mid-May Brings the Warblers’ Fellow Travelers

Lots of birds, even fairly solitary ones, join the warblers in the nighttime flow of  birds during  May, especially in the second and third weeks. Researchers have yet to solidly determine exactly how these small survivors navigate the skies. Current theories include  sighting landmarks below, orienting to the stars or sensing the earth’s magnetic field, or  all three. Ornithologists still aren’t sure. But aren’t we glad the birds mysteriously manage it?

On May 11, my sharp-eyed husband called me to the window again. And there I stayed for 20 miraculous minutes as a male Scarlet Tanager foraged  along the edge of the brickwork outside our back door.

A lucky look at the male Scarlet Tanager outside our back door.

I hoped he might stay around to nest, but no such luck. The birding group, though, saw both a male and a female with nesting material at Lost Lake Nature Park on May 29th.  Maybe I’ll see fledgling tanagers yet! Tanagers are “dimorphic,” meaning that males look different than females, in this case, though only in the breeding season. In the fall, the male changes into the yellow-green plumage of the female to travel to their wintering grounds in northern South America. Quite a trip for these small birds.

A female Scarlet Tanager at Tawas Point last year traveled right along with the warblers during migration.

A surprise for us at Magee Marsh this year was seeing a Great Crested Flycatcher (Myiarchus crinitus). I don’t get to see them much because once they settle down to breed, they hunt their insect prey high in the tree canopy. Sometimes other birders point out their distinctive call to me and I catch a glimpse of its lemon yellow belly from a distance. This time, I could get a bit closer! Cornell Lab of Ornithology says they “tend to migrate alone,” but this one was surrounded by hundreds of warblers.

The Great Crested Flycatcher actually crashes into the leaves at times in its enthusiasm for snagging insects.

I can’t say for sure when Indigo Buntings arrive in our area from Florida or the Caribbean, but I usually see them in the parks by mid-May. This year, though, we were lucky enough to see this deep azure male at our hulled seed feeder. (A popular place this year!) He came right at the end of May and for a week now has come every evening, right before sunset. I think we’re his stop for a bedtime snack. A writer at Cornell Lab described him perfectly as “a little scrap of sky with wings.”

A male Indigo Bunting that arrives at our feeder just before sunset this year.

Another latecomer to our feeder is the male Orchard Oriole (Icterus spurius) who has only been at our feeder one previous year and then only briefly. This one came to visit on May 29 and appeared daily since, eating the same grape jelly that pleases his bigger cousin, the Baltimore Oriole. Orchard Orioles migrate south again by the end of July so catch sight of one while you can. There’s often a pair at Bear Creek Nature Park.

The Orchard Oriole comes late and leaves early. They’re often seen at Bear Creek Park.

The presence of all these unusual birds at my feeder makes me wonder if a cold, wet spring has left some migrators without their usual diet of insects. So they’re settling for grain until the sun shines and more insect eggs hatch. Just a guess, of course.

Giving Our Migrators a Helping Hand

Year after year for millennia, this wave of brilliantly colored aviators find their way north to us in the spring. Long ago, the luckiest or most skillful avian navigators discovered the lake shores, forests, prairies, and wetlands that were full of the required food and shelter they needed along the way. These survivors learned to take advantage of  peninsulas to shorten the distance over water and toughed it out when they were unavailable. They followed lake shores or ocean beaches when storms blew. And at last they glided down onto fields, splashed into ponds, settled on shady branches in distant forests, fluttered down into the protection of stiff prairie grass, or poked their beaks gratefully into the mud of a fertile marsh. Somehow the young of these avian pioneers knew the paths of their ancestors and somehow that knowledge got passed through thousands of generations of Scarlet Tanagers, Indigo Buntings and all the others.

Wonder and a desire to understand and/or help these winged neighbors are, I think,  common responses to the miracle of migration each spring and fall. Some of us fill our feeders, set up and monitor nest boxes, or band birds to help ornithologists learn more.  Some learn when and when not to rescue nestlings and fledglings and how to do it safely. Some company executives agree to turn off their office lights at night, while some farmers and others pause their wind turbines when notified by experts of particularly heavy migration in the area. Some cat lovers keep their cats indoors until fledglings are strong enough to escape into the treetops. Some gardeners plant their gardens with an eye to supplying fruits and insects as well as beauty. Some simply accept the inconvenience of awkwardly located nesting sites around their yard, and decide to just sit back with a camera or a cup of coffee to admire the hard work of raising little birds.  It all makes a difference. However you express your appreciation for the presence of birds in our world, thanks for doing it.

Paint Creek Trail: Last Hurrah of Spring Wildflowers, Tiny Pollinators and Nesting Migrators

Since this week’s blog features a variety of wildflowers along parts of the Paint Creek Trail, I thought we’d start with a little visit to the creek itself, which is currently overflowing its banks. The Swamp Buttercup certainly seems pleased with all that moisture! (If you increase your volume, you can listen to the soothing sound of flowing water and birdsong!)

Well, with summer heat settling in, native spring flowers are producing a glorious finale to the season before making room for summer blooms. Spring wildflowers love the weaker spring sun sifting through bare branches. But hot sun and the increasing number of leaves mark the end of spring blooms. Soon these wildflowers will set their fruits, send it to the ground by means of wind, water or simple gravity, and their seed-based reproductive efforts will come to an end for the season.

So before they’re all gone, here are the ones I saw last week on the Paint Creek Trail between Gallagher Road and Dutton Road. You may still be able to spy some of these native beauties as you walk or bike on a sunny afternoon for the next few days.

Discoveries on the Trail between Gallagher and Silver Bell Roads

Golden Alexanders make a sunny yellow blanket beneath the trees just south of the Wet Prairie between Gallagher and Silverbell.

Golden Alexanders (Zizia aurea – above) should still be glowing beneath the light shade of trees near the Wet Prairie after Memorial Day. These members of the carrot family are visited by many spring pollinators, but they can also also self-pollinate. You can see them near the parking lot on Gallagher Road and at other spots along the trail as well.

In the Wet Prairie, a more unusual little wildflower is happily sprouting where the sun is full and the ground is moist. Blue-eyed Grass (Sisyrinchium angustifolium) is really a wildflower, though its leaves look like grass. Best to look for these dainty flowers on a sunny day, since the flowers stay closed on cloudy days.

Blue-eyed Grass on the Wet Prairie is best seen on sunny days.

Another unusual little wildflower huddles under its much taller grass-like stem on the Wet Prairie. Star Grass (Hypoxis hirsuta) shines up out of prairie on a 6 inch stalk topped by a small (3/4 inch) blossom. The six stamens with their angular anthers add to its star-like appearance. Maybe the dew on the leaf in the photo will help you sense the size of this tiny jewel of a wildflower.

Star Grass in the Wet Meadow with dew on a nearby grass leaf

Near the creek, just north of the Wet Prairie, a burst of orange caught my eye and I discovered a native flower that was new to me, Golden Ragwort (Packera aurea).  This plant too has multiple methods of reproduction.  Each of the tiny florets that make up the protruding center of the flower will produce an achene, a winged fruit enveloping a single seed that will disperse into the wind. But ragwort also produces underground stems (rhizomes) aid its spread!

Golden Ragwort brightens the bank edge of Paint Creek near the Wet Prairie

A native, fire-adapted plant which was new to me has the unusual name Bastard Toadflax (Comandra umbellata) and this is not a flax or a toadflax plant.  A report on desertusa.com, claims it was named “toadflax” by the 16th century botanist, John Gerard, because the flowers “be yellow, having a mouth unto a frog’s mouth” and “bastard” because at the time meant “false,” indicating perhaps that it was not a real toadflax. This interesting prairie plant is “hemiparasitic” because it feeds through its roots, but also taps into roots of other plants to get nutrition and water using special structures called haustoria. Bastard toadflax reproduces by rhizomes and produces a small oily fruits enjoyed by birds and mice, who by eating them carry the seeds farther afield.

Bastard Toadflax puts out underground suckers that tap into the roots of other plants.

If you notice a splash of white far back in the Wet Prairie, it might be a patch of  Robin’s Plantain (Erigeron pulchellus), a tough, little native that thrives after prescribed burns. It’s a relative of Daisy Fleabane (Erigeron annuus), a common wildflower in our parks. Unlike Daisy Fleabane, though, Robin’s Plantain more commonly produces one bloom to a stem. Like the Golden Ragwort, it reproduces by both achenes and rhizomes.

Robin’s Plantain, a relative of the more common Daisy Fleabane. Both thrive after prescribed burns.

Early last week, the fluffy, white blossoms of native Choke Cherry (Prunus virginiana) hung  in long clusters along single stems called racemes. After warmer sun later in the week, they had begun to turn yellow. They don’t produce edible cherries, but their bitter fruit appeals to game birds, songbirds and woodpeckers, according to one of my favorite wildflower sites, www.illinoiswildflowers.info.

Choke Cherry trees/shrubs don’t produce edible cherries, but rather a bitter fruit that appeals to birds, but not humans. But their blossoms are beautiful!

All long the trail you’ll see Wild Strawberry (Fragaria virginiana) blooming. Now here’s one bloom you might love to see fading, because its ripening fruit is tiny, but delicious. Good luck getting them before the birds and beasts do, though!

When Wild Strawberry blooms fade, on comes the fruit. But you’ll be lucky to get it before the creatures do.

Discoveries on the Trail from Silver Bell Road to Dutton Road

Despite our late spring, many different native wildflowers were blooming along this section of the trail.  At the bottom of the stairs leading to the creek, just past the parking area, Swamp Marigolds (Ranunculus hispidus) shine bright despite the deep shade. As you saw in the video at the top of the blog, the wetlands along the stream are doing what they do best – soaking up the runoff after heavy rains. And Marsh Marigold is doing its part!

 Farther down the trail, the lavender spikes of Wild Lupine (Lupinus perennis) are blooming. This beloved native produces seedpods open explosively, launching seeds up to seven feet from the plant. Lupine also produces colorful clones as it spreads with rhizomes. Lupines are rising toward the sun in several parks as part of the restoration work being done on our prairies. It’s so heartening to see these lavender blossoms opening up from bottom to top on their stately racemes. And I love the whimsy of its wheel-shaped leaves.

Both the leaves and blossoms of Wild Lupine make it a treasured native wildflower.

Along the berms on the western side of the trail, a perky yellow flower blossoms in bunches. The fuzzy stems and leaves give it the first part of its name, Hoary Puccoon (Lithospermum canescens). According to Wikipedia, the second word “puccoon” comes from an ancient Native American word “poughkone,” and refers to plants formerly used for dyes by Native Americans. I wonder if its roots can turn things that vivid yellow/orange?

The roots of Hoary Puccoon were used by Native Americans for dye. But please don’t pick them to try this at home!

Near the first bridge going south, I found a whole group of native wildflowers that were just finishing their blooms. A small group of Common Trillium (Trillium grandiflorum) still stood in the shade just off the trail. These flamboyant white flowers start turning pink as they age, eventually leaving only their leaves behind to gather up more sun for next years flowers. While true pink- and red-flowering trillium species exist, our Common Trillium just turn pink as they age gracefully.

Nearby Starry False Solomon’s Seal  (Maianthemum stellatum) bore only a rather disheveled version of its star-shaped blossom. After the blossoms, the plant will produce green fruits with purple/black stripes that eventually turn red. Woodland birds and mice enjoy the fruits, thereby carrying the seeds within the berries to new locations.

Starry False Solomon’s Seal has graceful leaves as well as tiny star-shaped flowers.

Native Bees and Tiny Butterflies Busy Pollinating

This may be a Mining Bee, a native pollinator, which specializes in Wild Geraniums.

Many spring wildflowers depend heavily on flies and native bees (of which there are 450 Michigan species!) for their pollination, because many other butterflies and the honey bees finish migrating or emerge from hives only in warmer months. Above is what I think is a native Mining Bee (Andrenidae family) foraging for pollen and thereby pollinating one Wild Geranium (Geranium maculatum) after another! I’m not knowledgeable about bees, but I learned from Pollinators of Native Plants that a particular Mining Bee, Adrena distans, is a specialist pollinator of Wild Geranium, so that’s my guess. Please feel free to correct me if you know more about bees than I do!

A few tiny butterflies were doing their part in pollinating flowers as well. If you see a fluttering wink of blue among the grass stems, it’s probably a Spring Azure butterfly (Celastrina Ladon). These 1 inch pollinators are blue when flying but once they settle, they quickly fold their wings so only the dull gray side shows. It makes them hard for hungry birds – and interested photographers! – to spot. Azures tend to pollinate Golden Alexanders, False Solomon Seal as well as other wildflowers. (Photo on the left by iNaturalist. org photographer Dan Mullen.)

The tiny Pearl Crescent (Phyciodes tharos) quickly fluttered by me and landed on dry grass stems in the Wet Prairie. These little butterflies produce several broods of caterpillars throughout the summer. So watch for tiny (up to 1.25 in.) flashes of orange and black rising from the grass and scurrying across trails all summer long, busily sipping nectar and inadvertently transporting pollen for the flowers.

The tiny Pearl Crescent can be seen now at the Wet Prairie and all summer long in our parks.

The last little butterfly was in a perfect spot to find a mate.  According to http://www.butterfliesandmoths.org, “To seek females, males perch in openings, flats or depressions near woods.” And that’s right where this one was – in the open, on a dead plant stalk near the trees just south of the Wet Prairie. He’s not glamorous but he has a glamorous name, the Dreamy Duskywing (Erynnis icelus). (Duskywings can be hard to tell apart, so again, feel free to correct me!) [Edit:  A man who collects butterflies and has seen many Duskywings told me on Facebook that he believes this is a Sleepy Duskywing (Erynnis brizo)  which he says are more common in this area.} He’s picked a great spot since one of his favorite nectars is the nearby wild lupine. These duskywings like to lay eggs on aspens and cottonwoods, which surround the Wet Prairie.

Possibly a Sleepy Duskywing  waiting on an open perch to be found by a mate.

Migrators Building Nests and, What Else? – Singing!

Late spring is a busy time for birds.  Some have just arrived and are busy singing to attract mates. A Warbling Vireo (Vireo gilvus) sang over my head in one of the Quaking Aspens (Populus tremuloides) near the Wet Prairie. This vireo is rarely seen once the leaves come on the trees; they like to stay high in the treetops and search diligently for caterpillars. But hearing a quick, rolling song high above me, I spotted his vireo shape, gray/olive back and yellow-ish white belly from below. Then he disappeared into the tree canopy. So here’s a photo of one I saw at Cranberry Lake a week ago. Click here to listen to his rollicking warble!

A Warbling Vireo sang above my head near the Wet Prairie. An illusive bird high in the trees with a great song!

The Warbling Vireo near the trail seemed quite frantic, singing insistently and hopping higher and higher in the tree as he did so. At first I thought another male vireo was singing across the trail from him – and I believe that he thought so too! But when I followed the other song, it was one of the great bird mimics, the Gray Catbird (Dumetella carolinensis), doing an imitation of the Vireo’s song and, I think,  driving him crazy! The Catbird was, as usual, adding a few flourishes of his own, but it seemed as though the Vireo found his call an annoying form of competition! For a sample of the Catbird’s wonderfully complex, mimicking song, click on the word “Song” at this link.

The Catbird’s mimicry of the Warbling Vireo’s song seemed to fool the vireo into thinking he had competition!

A pair of Baltimore Orioles (Icterus galbulaswooped down onto the Wet Prairie one afternoon. The female immediately disappeared into tall grass. It’s likely that she was carefully choosing grass stems out of which she could strip fibers for weaving her long, sack of a nest. Evidently, the male’s job was to stand guard while she had her head down.

A male Baltimore Oriole stands guard while his mate searches for just the right plant fibers to weave her bag-like nest.

Suddenly, the female oriole lifted out of the grass, followed immediately by the male, and they swooped into a tall Cottonwood (Populus deltoides) on the northern side of the prairie. She disappeared into a clump of leaves hanging high over the meadow, but I could see the branches moving as she worked and a tiny bit of the growing nest  (look in the center of the photo below through the leaves). I found a great little YouTube video of the Oriole’s weaving process, which is really incredible. Imagine tying knots and twirling fibers around a branch using only your beak!

The beginnings of an oriole nest high over the Wet Meadow

I heard a pair of  Eastern Kingbirds (Tyrannus tyrannus) fluttering together from tree to tree and stopped to watch. After giving what sounded like greeting calls, they soared up into a tall tree near the Wet Meadow. The female stood at the edge of a very messy nest which she was constructing on top of what appeared to be an old squirrel nest. The male doesn’t help build the nest, so while she worked, he stood guard in a nearby tree. I read in the Stokes Guide to Bird Behavior (Vol. 1) that Kingbirds build preliminary nests before settling into a final one to lay eggs. I’m guessing this may be just a trial nest, since building on a squirrel nest seems like an iffy location! (Squirrels are known to eat bird eggs!) The fine fibers drooping down over the top of the squirrel’s dry, gray branches and leaves are the female kingbird’s doing.

A female Eastern Kingbird seems to be constructing a preliminary nest on top of an old squirrel nest.

Kingbirds are identifiable from a distance by their upright posture – what one member of the birding group calls their “military stance.” And note the white tips on the tail feathers.

Every Nature Walk has its Special Moments

Last week, I had to smile at this seemingly relaxed male Northern Cardinal (Cardinalis cardinalis). He hopped slowly up and down a slope by the trail, picking up and rejecting items he found between the grass stems. With the grass taller than his head and his red crest (which is usually erect) drooping backwards, he reminded me of an avian Red Riding Hood!

It’s little things like that – and seeing the Blue-eyed Grass staring up at me – or watching the two Eastern Kingbirds near their nest – that send me home happy from every foray into the natural world. And these grant adventures only require the right clothes for the weather, water-proof shoes, a little application of bug spray at times and my undivided attention for an hour or so. I usually take my camera along,  but walks without anything but my trusty binoculars are just as rewarding. If you ever feel a bit weary as the poet Wordsworth once did, “The world is too much with us, late and soon/Getting and spending, we lay waste our powers…,” try a foray into our parks with your curiosity set at high alert. I’m confident that nature will send you home refreshed and with moments to share with others. Thanks for sharing mine!

NestWatch: Being Citizen Scientists in Our Backyards and Parks

A faithful male Rose-breasted Grosbeak takes his turn on the nest at Bear Creek Nature Park.

On March 21, Dr. Ben VanderWeide, the township’s Natural Areas Stewardship Manager, shared a Cornell Lab of Ornithology presentation on how to safely and accurately monitor bird nests as citizen scientists. Cornell Lab and other researchers count on citizen scientists to provide important information on the nesting success of common birds in our backyards and our parks. If you’re intrigued by this introductory information, there’s a lot more available at www.Nestwatch.org. It’s an amazing resource, as you’ll see by all of the links below!

First, the Rules of the Road

The Eastern Kingbird looked proud of her handiwork once she finished her nest.

Cornell’s Nestwatch has an official “Code of Conduct” for nest monitors to ensure that the data is collected while protecting native birds, their nests, eggs, and young. It’s important that monitoring doesn’t attract predators and that parent birds don’t desert the nest.

  • Please don’t touch the nest, the birds or the eggs when checking nests or nest boxes!  Migratory Birds are protected by the Migratory Bird Treaty Act.  They cannot be harassed or harmed.  The only exceptions are those of aggressive invasive bird species like House Sparrows (Passer domesticus) and European Starlings (Sturnus vulgaris) that are not from North America.  (See more info on predators below.)
  • Don’t check nests in the early morning, which is when birds typically lay their eggs.  If the female leaves the nest during monitoring, the eggs may become too cool.  Afternoons are best for monitoring.
  • Avoid nests during the first few days of incubation. Only approach if the parent bird has left the nest.
  • If monitoring a nest box, tap softly on the box to allow the female to leave if she’s present. Or try singing or talking softly as you approach the nest.
  • Don’t approach nests when baby birds are close to fledging so they won’t try to leave the nest before they are ready. Once young birds are alert and fully fledged, only observe from a distance.
  • Avoid monitoring nests in bad weather like cold, rain, etc., when birds need the nest or nest box for protection
  • Don’t check nests at dusk or after dusk when females may be returning. Again, afternoons are best. The exceptions, of course, are owls who leave their nests at night.
  • Approach and leave the nest site from different directions at each visit so that you don’t create a path for predators like cats, raccoons, etc.
  • More details about the “Code of Conduct” at this link

Collecting and Recording What We Learn

A Cedar Waxwing nestling
  • Visits to the nest should be no longer than a minute. Take a quick look and jot notes at a distance. Use binoculars for more distant cup nests.
  • Check the nest every 3 or 4 days. Checking more often risks disturbing the nest; less often makes the information less useful.
  • Record when the first egg was laid. Birds normally lay only one egg per day, so the number of eggs tells you when she laid her first one. Easy, eh?
  • Record the number of eggs and any interesting bird behavior. (Cornell provides data sheets for this.)
  • Record your data at Nestwatch.org. If you’re working on backyard birds, start an account and you’ll be provided with an online form for entering your data. If you want to volunteer to monitor in our parks or along the Paint Creek Trail, please join our Oakland Township Parks NestWatch Chapter by contacting Dr. Ben at bvanderweide@oaklandtownship.org or call the office at 248-651-7810. You’ll need to take a brief quiz after reading the Code of Conduct material at Cornell in order to be a certified bird monitor.
  • More details on collecting data at this link.

Finding Nests in Our Backyards

  • Check out information on typical nest locations and materials for the birds in your yard by going to http://www.allaboutbirds.org. or a bird/nest field guide.
  • Watch where males are singing to establish their territories or listen for females who sometimes sing from the nest.
  • Watch for birds carrying nesting material like moss, twigs or grass.
  • Watch for birds carrying food, like caterpillars or worms, to feed the young.
  • Listen for frantic calls of young birds begging to be fed.
  • Check out areas where you’ve seen nests previous years. Though birds seldom reuse the same nest, they often nest in the same area.
  • More details  on finding nests here.

Setting Up and Monitoring Nest Boxes

Dr. Ben and Tom Korb are trying two different kind of Eastern Bluebird (Sialia sialis) boxes in the township – the traditional ones seen above, and Petersen boxes (see left) which have a more triangular shape.

A Peterson bluebird box

We’ll learn which style our bluebirds prefer. They’ve paired the two types bluebird boxes to see which box design our local bluebirds prefer. Paired nest boxes may also help with competition from Tree Swallows. Others have found that if Tree Swallows (Tachycineta bicolor) occupy one box, they will live peaceably with bluebirds next door. We’ve also installed American Kestrel (Falco sparverius) boxes and a box for smaller birds such as chickadees, nuthatches, or Prothonotary Warblers (Protonotaria citrea).

For details on building/buying nest boxes for your back yard, check out this helpful page on nest boxes at  Nestwatch. For more detailed plans on bluebirds and their houses, check out the website of the North American Bluebird Society or this link at Sialis.org. Nestwatch even shows you the right house for the birds in our geographic area.

Beware of Predators!

Predators can approach native birds from the sky and the ground. (Click on photos to enlarge; hover cursor for captions.)

Ground Predators
  • Raccoons and outdoor or feral cats are major predators for birds. A well-respected, peer-reviewed study cited by Cornell found that as many as 1.3 to 3.3 billion birds are killed by cats each year in North America. They are skilled bird hunters! And raccoons can wipe out a whole group of nests in an evening!
  • Keeping pet cats indoors is a great idea if at all possible.
  • Make sure your nest box is at least 6 feet off the ground so raccoons and cats can’t jump on top of the box. If they do, they “fish” for eggs and chicks through the hole.
  •  The right roof and predator guards on the bird house pole can make a big difference.
  • Avoid leaving pet food or birdseed on the ground, which encourages predators.
  • Keep your nest box away from overhanging trees to keep squirrels from dropping on them and chewing the holes to get in.
  • Snakes can be deterred by locating nest boxes away from brush piles or by putting a metal collar/predator guard below the nest box on the pole.
Bird Predators

Aggressive, invasive birds, especially the House Sparrow and the European Starling, will attack and kill native birds, their eggs and their young to take over a nest box. Because they are non-native and plentiful, they are not protected by the Migratory Bird Treaty Act.  So how to deal with these predatory characters?

  • If you don’t want to deter invasive birds, please  consider not putting up bird boxes. These invasive birds are already abundant and  actively attack and kill our native species. Providing them with food and a nest merely exacerbates the problems for native birds.
  • Choosing an appropriate entrance hole size on a nest box is important. Starlings can enter and attack American Kestrels in their boxes – but starlings are too large for a bluebird box if the entrance hole is the right size. House Sparrows, however,  can easily attack bluebird boxes. NestWatch has more information on passive and active means of deterring these non-native predators – from changing nest location to removing nests and eggs or trapping adult birds.
  • Be sure you know what Starlings look like and are able to distinguish House Sparrows with their black triangular bibs from our many species of native sparrows.
  •  These two invasive birds make messy nests with bits of plastic, cigarette butts, paper, etc. so distinguishing them from native nests is easier once you are informed about the appearance of your native bird’s nest.
  • Native birds, like House Wrens (Troglodytes aedon),  occasionally attack other birds to take over a nest as well. And native Brown-headed Cowbirds (Molothrus ater) lay their eggs in the nests of other birds. Because these birds are naturally occurring species in our area, they are protected by the Migratory Bird Act and should not be removed or harmed.
  • Bees, wasps, squirrels and mice can inhabit nest boxes at various times of the year. Nestwatch has info on coping with them, too.

Helping our native birds raise their young in safety is crucial to slow the declining numbers of many bird species. Bluebirds, for example, were threatened until citizens began a campaign of installing and monitoring bird boxes for these azure beauties. The data from nest monitors since NestWatch began in 1965 has provided vital information on over 600 species and resulted in 133 scientific articles and 9 ongoing studies. With the data the public collects, researchers can detect  shifts in bird populations related to landscape and climate change. Saving native birds is important to preserving the beauty of our local natural history.
