Cranberry Lake Park: Here Come the Migrators, There Go the Hibernators

Birds and butterflies flock to Cranberry Lake Park year ’round. The wide range of habitats there – a lake, wooded wetlands, huge meadows and acres of forest – provide food and shelter during the  summer for a wide range of different species. And migrators make it a regular stop-over in the spring and fall, this autumn being no exception.

Last week, little warblers flitted from limb to limb, keeping the birding group busy trying to spot them all by eye or ear. And in the meadows, the special “super-generation” Monarchs that hatched in late summer sipped from and floated above the asters and goldenrods before beginning their long migration to their wintering grounds in Mexico.

Migrating Birds Ride In, While Local Fledglings Bulk Up

When a north wind blows in the dark of night, getting out to the meadows in the morning can be a rewarding experience. Warblers and other migrators from farther north fly and float in using those winds to support them. As migration begins, being partially carried by the wind on a dark night saves energy and also avoids hawks and other predators that fly in the sunlight.

The birding group heard and saw the first flush of these seasonal nomads on their September visit to Cranberry Lake Park. Our first encounter was with a busy Black-and-White Warbler tracking up, down and around tree trunks on the Hickory Lane that runs down the western edge of the park. A tiny bird moving fast in dense shade meant that none of the birders got a decent photo. But since these beautifully patterned warblers wear the same plumage fall or spring, here’s a springtime shot when foliage was less of a problem!

The Black-and-white Warbler moves around branches much like a nuthatch.

Unfortunately, I missed most of the warblers on the Cranberry Lake Park bird walk by suddenly feeling ill. So fellow birder and fine photographer Joan Bonin was kind enough to share a few of her photos with me! Thank you, Joan! The group spotted a Magnolia Warbler (Setophagia magnolia) in its fall plumage, which as you’ll see in my photo on the right below is a lot different from its spring courting colors! It’s headed for the Bahamas like the Black-and-White. I hope the devastating hurricane there doesn’t mean trouble for them. Best of luck, little birds!  [Click on photos to enlarge; hover cursor for captions.]

Joan got a shot of a Black-throated Green Warbler (Setophaga virens) which is also headed to the Bahamas. It too wears less flashy plumage in the non-breeding season.

Ben caught sight of a  Chestnut-sided Warbler (Setophaga pensylvanica). Using his description and The Warbler Guide by Tom Stephenson and Scott Whittle, I think it probably was either a female in fall plumage or a first year male or female, because it had a clear breast with no chestnut streaks on its side. Since no one got a photo, I found one from a  generous photographer who uses the name “thejasperpatch” at the iNaturalist.org website. Thank you!

The male Chestnut-sided is one of my favorites because of its varied color and pattern. These tiny birds are headed for Central or South America to hang out with a flock they forage with every year – much like human friends who meet up in Florida each winter! Here’s my photo of a male prepared to charm the ladies in his spring plumage.

The Chestnut-sided Warbler spends each winter with the same group of tropical birds in Central or northern South America .

Ben also heard the slightly rough-edged,  two or three note song of the Yellow-throated Vireo (Vireo flavifrons), but the birders could never spot it in the thick foliage. Vireos often accompany warblers on migration. This one was probably planning to spend the winter in the Bahamas too, though they also winter in Cuba. The yellow “spectacles” are one of its distinguishing features. Here’s a photo by fine photographer BJ Stacey at iNaturalist.org .

Fledglings need a bit more sustenance before heading south. Before I departed on birding day, I got a quick photo of a  juvenile Eastern Towhee (Pipilo erythrophthalmus). It jumped excitedly from branch to branch, waiting for its parent, who periodically flew in to quickly stuff food in its beak. According to the Stokes Guide to Bird Behavior (Vol. 2), adult Towhees feed their fledglings for about a month after they leave the nest. At first the young stay in dense foliage, then gradually wait in more exposed places like the one in the photo below. Shortly, this young one will join with other juvenile Towhees to eat and hang out together like any adolescent. Fortunately, understanding adult towhees will allow them to cross their territories to do so.

A juvenile Towhee waited anxiously for its parent to bring food.

A week earlier in the same area, my husband and I had heard a male Towhee making his territorial “wheeet” call. When we spotted him, he gave us a sharp warning glance. I wondered at the time if his young were nearby. Maybe that alert male was the hard-working parent feeding the youngster that we birders saw a week later. I’d like to think so.

The Towhee went on alert once he spotted us.

On a cool, wet morning, a fledgling House Wren (Troglodytes aedon) perched on its own, looking out across a meadow. Other young wrens called to one another farther along the trail, so this one was probably waiting for an adult occupied with feeding its siblings. Before they migrate, wrens become quiet and remain hidden in the greenery frequently where they winter in the southern Gulf states and Florida. Southerners miss out on the male’s glorious spring song. Aren’t we the lucky ones?

A Wren fledgling appeared to be out on its own one cool wet morning but it’s likely that its parent was nearby, feeding its siblings.

Joan Bonin also snagged a photo of a  Broad-winged Hawk (Buteo platypterus) who was probably headed south toward the tip of Florida or Cuba. In autumn, huge “kettles” of these birds with thousands of individuals make their way south together. (See photo of a “kettle” at the top of this section.) Two birder friends and I saw a huge circling flock last year at the Hawk Fest in Amherstburg, Ontario, though this year the festival was canceled at the last minute  by a  storm severe enough to bring down trees. All this severe weather is a serious threat to migrating birds!

A Broad-winged Hawk flew over the Cranberry Lake birders, heading toward the tip of Florida and Cuba.

Monarchs Everywhere on a Cool, Autumn Morning!

The migration of the “super-generation” Monarchs is well underway. These heroes of the insect world – the last generation of Monarchs to hatch here in the upper Midwest and Northeast  – will live for 8 months, instead of the 5-7 weeks of all other Monarchs. They make the entire two-month journey of 3,000 miles to Mexico, spend the winter, and then fly back north to mate. There they lay the eggs for the first of the 4 to 5 generations of short-lived Monarchs who will successively produce their progeny, eventually ending this relay in Michigan each spring.

A Monarch, its proboscis ready for its next sip, flies above the Showy Goldenrod.

Alone at the park on a cool, wet morning, I saw twenty-one Monarchs in my first ten minutes! I stopped counting, took a few photos and then just enjoyed the sight of them slipping up out of wet greenery where they’d spent the night. They shivered upward, shedding dew, looking like vivid autumn leaves reversing their descent. It seemed that with every step I took, more of them rose from the moist meadow. A peaceful, quite magical sight. Here’s a short slideshow of just a few of them on the plants on which they’d rested the night before.

Monarchs were feeding close together as in this photo with two Monarchs in the foreground and one that’s just an orange blur in the background. Aren’t they just spectacular in their golden setting? What beautiful, delicate and surprisingly tough long distance athletes they are!

Other Wings Over the Meadows

The dragonflies and their slimmer relatives, the damselflies are on the wing in late summer and early autumn, too. In August, we saw a dragonfly that was new to me, the Slaty Skimmer (Libellula incesta), with a dark blue body and black head. It was above the lake trail which is lined with wooded wetlands, this dragonfly’s favorite habitat, according to the Odonata Central website. Ben got the best photo of it.

This Slaty Skimmer perched in the open, probably trying to attract a mate.

Meadowhawk dragonflies (genus Sympetrum) mate and lay eggs in July and August so they are plentiful right now. Determining a specific species in this genus is not possible unless you’re an expert with one in hand. But the males are almost always red and females and juveniles are usually yellowish brown or black and many have chevrons on their abdomens.

I was fortunate to get an identification on one Meadowhawk I saw because it had some distinctive features like yellow legs, a generally unmarked thorax and a scoop-like spatulate end to its abdomen. This is likely a female Autumn Meadowhawk (Sympetrum vicinum) as identified by people more experienced that I on the “Odonata of the Eastern United States” Facebook page.

An Autumn Meadowhawk rests in the sunlight on a September morning.

According to the Minnesota Dragonfly Society website, “Some dragonflies…point their wings forward and down in order to reduce exposure to sunlight and, perhaps, to reflect light and heat away from their bodies.” On really hot days, they’ll point the tip of their abdomen straight up toward the sky to have as little exposure to the sun as possible. Getting warm or cooling down take some acrobatics from these cold-blooded creatures!

Damselflies, another member of the order Odonata, are always busy in the summer and early fall at Cranberry. Unlike dragonflies who generally rest with their wings spread outward, most damselflies rest with their wings closed.  One family of damselfies, the Spreadwings (family Lestidae), cling to plants with their wings just slightly spread. This Spotted Spreadwing (Lestes congener) at Cranberry Lake Park in September shows this common wing position for spreadwings. How about those eyeballs!

I love the big, blue eyes on this Spotted Spreadwing damselfly!

The female Slender Spreadwing (Lestes rectangularis) can almost disappear with its clear wings and its unusually long, gray-to-black body, especially since it loves the shade.

Slender Spreadwings love the shade and that’s where I found this one.

Now admittedly, the Tussock Moth’s Caterpillar (Euchaetes egele) isn’t fluttering just now, but it plans to! Of course, it will need to chew on quite a lot of Milkweed before it builds its cocoon and waits until spring to transform. The adult moth’s chunky yellow body lined with black dots  is hidden under a pair of subtly elegant beige wings. I’m still on the hunt for the moth (which you can see at this link), but for now, I’m enjoying the floppy, mop-head look of the black and orange caterpillar.

Milkweed Tussock Moth caterpillars will soon spin a cocoon where they’ll spend the winter until they emerge with wings in the spring.

 

Amphibians Still Visible, but…Hibernation Awaits!

A small Green Frog (Rana clamitans) at the edge of Cranberry Lake in September will soon settle on the muddy bottom and breathe through its skin throughout the winter.

In August, I saw a lot of tiny amphibians near Cranberry Lake! The young Leopard Frog  (Rana pipiens) my husband I saw will shortly be heading for the bottom of the lake to spend the winter just as the Green Frog above does – on top of mud on the lake bottom, breathing slowly through its skin.

The Leopard Frog has been in decline since the 1980’s but can be see in several of our parks.

When the temperature drops, the tiny Wood Frog (Rana sylvatica) that Ben picked up on the bird walk will travel upland to hibernate inside a log or under leaves. According to National Geographic’s website, once its body starts to freeze, its liver produces a kind of internal “anti-freeze,” a very sugary glucose solution which is then packed into the cells so they don’t collapse, like human cells do when frozen. The little frog will survive if no more than 67% of its body freezes. Its brain activity stops, its heart stops and it’s frozen solid! But in spring, it thaws and hops away! It can even tolerate our Michigan freeze-thaw-freeze cycles! By the first frost, this little one will be bigger and ready for the big adventure!

This tiny Wood Frog will freeze solid during hibernation this winter and thaw in the spring!

So many Eastern American Toads (Anaxyrus americanus) were springing from under our feet in August that we had to be cautious not to step on them! They often hatch simultaneously and may stay together for some time afterward. Once cold weather sets in, they can dig a hole up to 3 feet deep with their hind legs and essentially back into the hole, the dirt falling in to cover them as they get deeper. Then their metabolism slows as it does for all hibernators and they remain in torpor for the winter.

Eastern American Toads often return to their natal ponds year after year.

The tiny Gray Tree Frog (Hyla versicolor) is bright green when it’s young  (see left below),  but becomes gray, brown or green, usually with a black pattern, when it matures (right below). Though the mating season is over for them now, the males are singing in September anyway, especially when it rains. We hear one singing from an unused hood vent outside our kitchen window! Like the wood frog, it can survive when its body freezes, thaw out in the spring, and be just fine.

Fall Has a Special Kind of Excitement, Doesn’t It?

A Sheet Spider’s web between Showy Goldenrod at Cranberry Lake Park

We often think of the fall as brilliantly colored falling leaves – and of course, that’s coming. But in this early part of fall, as days occasionally turn crisp and nights get chilly, so much more is going on!

Spider webs bejeweled in dew shine in the morning sun as spiders prepare to snag more insects before cold weather begins.  Bright yellow goldenrods are now complemented by purple flowers, like New England Aster. Acorns and hickory nuts tumble to the ground and are quickly stored away by squirrels and chipmunks. Large hatches of tiny, late season Red-legged Grasshoppers spring from the grass below our feet as we hike the trails. They must hurry to grow, mate and lay eggs before the ground hardens.

Some birds disappear for a while to change into their winter colors. Others relinquish the territorial fierceness of breeding season to gather in huge flocks, flying in formation or whirling high overhead. Small ones fly singly through the dark, only stopping to eat and rest, before moving on.

And we humans stock our larders with summer produce – berries in the freezer, peaches in bottles, apples at the fruit stand. We repair a leak in the roof, wash the dust off the storm doors, pull jackets and sweaters from the backs of closets – or make arrangements to pack up and migrate south with the birds. All of us animals, human and otherwise, know that as day and night equal out at the equinox, preparations must be made! And so it begins….

TINY, INTREPID MIGRATORS: The Colorful Warblers of Late Spring

Polish up your binocular lenses and head outside, dear readers!  The trees, shrubs and marshes are filled with a rainbow of colorful birds. And though some of these visitors may choose to stay and raise young here, others are just passing through.  So time’s a-wasting!

The second and third weeks of May are probably the busiest weeks of the spring for those of us who enjoy birds. New birds arrive daily at our feeders and we rush to the window. Flocks gather at  birding ‘hot spots” like Tawas Point in Michigan or Magee Marsh in Ohio and we pack up the car and take off to see them.  Familiar birdsong in the treetops prompts the birding group to go silent and look up.

A tree full of busy warblers captivated the birding group in May 2018.

Scientists theorize that the tiny warblers, and many other spring birds, may have made long, arduous journeys through the night ever since their ancestors in the tropics experimented with moving north in the spring.  As the glaciers retreated, some of the tropical or sub-tropical birds kept pushing on a bit further north each spring, seeking more sunlit hours and different or more nourishing food. Those ancestors liked what they found –  longer summer days, an abundance of blossoms and insects and plenty of nesting sites. And lucky for us, they eventually arrived here in Oakland Township and liked what they saw.

This year,  I got curious about  where our visiting warblers spent the winter. How far had they  traveled to reach Michigan from their wintering grounds? I also wanted to be sure which birds you and  I need to look for right now, before they fly off to breed further north and which ones we can relax about a bit, because they’ll spend the summer with us, raising their young in our parks and yards. The more I learn about nature, the more I feel myself embedded in the natural world – and I like that feeling.

So here’s what I’ve learned about some visiting warblers so far this month. These birds are all ones I’ve seen this spring. But I’m using some of last year’s photos  when they’re better than some of the ones I took during this year’s cold, rainy spring. Next week, I hope to explore the fellow travelers, other beautiful migrators that accompanied this year’s warblers  and will be spending the summer with us as well.

Some Warblers are Here Only Occasionally or are Just Passing Through

Evidently for some birds,  our area is a good place to get some R & R, but locations further north have charms that lure them on.  Perhaps these migrators long for cooler summer temperatures, deeper forests, or a reliable food source that they need or simply prefer.

At Magee Marsh in Ohio, my husband and I saw our first male Prothonotary Warbler (Protonotaria citrea), named for the bright yellow robes of Roman Catholic papal clerks.  You can’t see this male’s lovely blue-gray wings in my photo because he wouldn’t stop singing his four tweet song.  I think his clear golden feathers with a peachy blur are probably the prettiest yellow feathers I’ve ever seen! Prothonotary numbers are dwindling due to a lack of forested wetlands in the U.S. and the loss of mangrove forests along the Atlantic Coast of Central and northern South America, where they spend the winter.  They more commonly breed in Missouri, Arkansas and the south but a few do choose to breed in our area.  Some were seen along the Clinton River Trail in the last couple of years. So,  enjoy a rare treat if you spot this beautiful warbler!

The Prothonotary Warbler has blue-gray wings that don’t show here because he was too busy singing to hop about!
The male Blackpoll Warbler (Setophaga striata) below may look like an overgrown Chickadee, but Blackpolls are avian record-holders!  Cornell Ornithology Lab reports that, “This long-distance athlete weighs less than half an ounce yet makes the longest overwater journey of any songbird—nearly 1,800 miles nonstop over the Atlantic Ocean to its wintering grounds.”  Imagine!   Now they are on their way to mate in Northern Canada; some go all the way to Hudson’s Bay! According to Cornell Lab, to accomplish their monumental autumn flights, Blackpolls have to double their weight!  Talk about bulking up!
The Blackpoll Warbler can fly over the Atlantic for 3 days nonstop on its way to its wintering grounds. Though still quite numerous, their numbers have fallen 88% in the last 40 years.

This male Magnolia Warbler with its black necklace and mask was on its way to Northern Michigan or Canada because he prefers to breed in dense conifer forests.  And he’s already traveled a long way since he winters in the Caribbean or Central America.

This male Magnolia Warbler (Setophaga magnolia) spent his winter in the Caribbean or Central America. He’s on his way to the conifer forests of Northern Michigan  of Canada.

Blackburnian Warblers (Setophaga fusca) travel super long distances, too.  According to Wikipedia, they winter in the mountains from Colombia to Peru at heights of 2,000-8,000 feet.  They also prefer to breed in coniferous forests, especially ones with hemlocks.  So they’re heading farther north to upper Michigan and Canada.  While there, they’ll spend most of their time in the high canopy, plucking moth and butterfly larvae from the treetops.  So the best time to see them is during migration when they’re down at eye level.

The Blackburnian Warbler travels here from mountainous areas from Colombia to Peru

The Northern Parula (Setophaga americana) spends its winters in Mexico, the Caribbean or Central America.  Parulas raise young from Florida to the boreal forests of northern Canada, but according to Cornell, they skip Iowa, Michigan, Wisconsin and some northeastern states.  Why avoid us?  Mosses like the southern Spanish Moss (Tillandsia usneoides)  or northern lichens like Old Man’s Beard (g. Usnea) that droop from branches are important to the Parula for nesting material and neither is common in our area.  So since they breed north of us and south of us but not here,  try to see them before they move on!

The Northern Parula’s  rust-colored throat isn’t visible in this photo.  It breeds in many states but not here since we don’t have the tree mosses  or lichens they depend on for nesting material.

According to the migration map at Cornell, the Yellow-rumped Warbler just barely misses our area during the breeding season.  They  breed north of  Michigan’s “thumb.”  The reason may be that,  like the Blackburnian, they prefer mature forests with more conifers in them than we have around here.  Luckily, during migration,  I’ve seen them many times at Bear Creek Park, either around the playground pond or in the oak-hickory forest.  They can winter as far north as Indiana and Ohio (rarely in the southern edge of Michigan) because they can digest fruits that other warblers can’t,  like juniper or myrtle, but also the fruits of poison ivy, poison oak and virginia creeper, for heaven’s sake!   Strong stomachs, eh? This one rested at Magee Marsh this year before crossing Lake Erie.

The Yellow-rumped Warbler prefers the conifer forests of Canada as nesting territory.

During migration, I’ve spotted Palm Warblers (Setophaga palmarum) year after year at Bear Creek Nature Park. Their song is a rapid buzzing trill,   Look for Palm Warblers on the ground, a location uncommon for most warblers.  They also do a lot of tail pumping while they forage. Palm Warblers prefer to nest in the boreal (evergreen) forests of Canada. Their migration north begins in Florida or the Caribbean.

Palm Warblers spend a lot of time on the ground, which is unusual for warblers.

Some Warblers Spend the Summer With Us.

All summer long, we are graced with the presence of other warblers.  They are small and can be difficult to see hidden in the summer greenery, though, so it’s a delight to see them before the leaves are fully grown.  I have yet to see a warbler nest, but I’ve only become aware of these little beauties since I joined the birding group, so maybe you long-time birders have spotted them raising young. If so, I’d love to hear about it in the comments section below!

The Chestnut-sided Warbler (Setophaga pensylvanica), one of my favorite warblers,  is shown on Cornell Lab’s migration map as  nesting here in our area,  but I’ve only seen them during migration.  Please let me know if you see one during the summer or hear what Cornell describes as their “pleased, pleased, pleased to meetcha!” breeding song. These little birds spend their winters among tropical birds in Central and northern South America. They tend to go back to the same tropical area each autumn and  hang out and feed with the same mixed group of tropical birds they hung out with the previous year. I’d love to see that reunion each year!

The Chestnut-sided Warbler spends the winter with the same group of tropical birds in Central or northern South America.

Happily, the Yellow Warbler (Setophaga petechia) is a common summer resident in our parks.  These bright yellow birds are likely to be in shrubs or trees near wetlands.  The male’s very quick “sweet, sweet, I’m a little sweet” call can be heard at quite a distance, so keep following that call! This tiny bird is also a long distance migrator.  Yellow Warblers fly non-stop across the Gulf of Mexico to spend the winter in Central America or northern South America. Wouldn’t their tropical ancestors be proud of them?  (Click on photos to enlarge; hover cursor for captions.)

Some of our eastern American Redstarts (Setophaga ruticilla) only travel to Florida for the winter.  But many fly on to the Greater Antilles (the large islands in the Caribbean) or to northern South America.   Listen for its cheerful song since they mate in our area, as well as over a large area of the  country. The Redstart is believed to startle insects out of trees by simultaneously drooping its orange-patched wings and flashing open its colorful  tail. It must work, because Cornell says that they excel among the warblers at catching flying insects.

The intricately  patterned Black-and-white Warblers (Mniotilta varia) hop along, around, over and under the trunks and branches of trees, much like nuthatches,  looking for insects in the moss and bark. They can nest here, though I’ve only seen them during migration and don’t yet recognize their rapid, shrill trill.  They build nests  on the ground in forest leaf litter, so we’re more likely to see them in parks than on our tidy lawns.  They are scrappy little birds that give the Redstarts and Chickadees a hard time when establishing territory. Some travel to Florida for the winter, but others fly on to northern South America where they hassle inhabitants there as well!

The Black-and-white Warbler hops about on trees and branches searching for insects or insect eggs,  much as the Nuthatch and Brown Creeper do.

The birding group sees  or hears Black-throated Green Warblers (Setophaga virens) during migration.  The maps at Cornell Lab shows that some breed here, but they’re more likely to nest farther north in forests with mature trees. There they often feed high up in the canopy.  So really, the best time to see them is when they’re migrating because they tend to stay further down in the greenery. Though they do have a mating song, we’re most likely to hear their buzzing “zzzzz” territorial song while they’re traveling.  The mating song is the first recording at this Cornell link and the buzzing call is the second one.  They may have migrated up  from the Caribbean. Or they may have traveled from Central America and northern South America, either around or over the Gulf of Mexico.

Listen for the buzzing “zzzzz” call of The Black-throated Green Warbler to locate it during migration.

Birds Flowing Over Us  in the Dark Night Sky

Imagine standing on your lawn in the dark on a warm spring night.  Though you can’t see them in the dark sky, a river of small birds, dressed in their best courtship colors, are  alternately soaring and fluttering as they ride the south wind.  Most of  the smallest ones travel in large mixed flocks for safety.  For hundreds of miles each night, they wing their  way beneath the stars.  They’re battered by unexpected cold fronts and rainstorms that force them down  to the earth, sometimes in places unsuitable for rest or foraging. They rest, try to forage and fly on.  They dodge predators like owls  or suburban cats that patrol the night and hawks and other predators by day.  They fly on. Some are confused by the bright lights of buildings or towers and break against unseen glass or metal, falling to their deaths by the millions each year. But luckily, others manage to tilt their wings, swerve away or over these obstacles and fly on.  Driven by the need to find the optimum habitat for raising their young,  these colorful small birds persist in the journey defined by their tropical ancestors thousands of year ago.

Now these lovely, hungry, weary travelers have arrived or  at least have chosen to stop, rest and eat here before continuing on.  It seems only right that we take a little time to appreciate them.  Their bustling activity,  brilliant color and cheerful song provide a welcome change after the quiet, cold, gray-and-brown landscape of  winter.  Now that I’ve come to know some of them, late spring is even more of a joy.  I wish that for you, too.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

PHOTOS OF THE WEEK: A Warblerfest at Two Township Parks

Fellow birder Tom Korb’s photo of Oakland Township birding group watching spring warblers.

I doubt that many of the  birders in Tom Korb’s photo above had previously spent over half an hour observing a small group of trees with sheer delight. But of course, these trees at Cranberry Lake Park were decorated with colorful, little spring warblers! The warblers and other migrators had flown in on a south wind the night before and were now hungrily feasting on sweet spring catkins. Most of  these tiny birds will rest here and then fly farther north, so there were no territorial or mating squabbles. They were content to just nibble and flutter from limb to limb among their traveling companions as we eagerly watched below.

The same phenomenon occurred at Bear Creek Park the week before. A south wind had helped carry warblers and other small birds over the township and then heavy rain had forced them down out of the skies to settle in the trees around the playground pond.

So here’s a gallery of the photos I was able to catch of these tiny, flitting warblers, and a few bonus birds. For birds that we saw or heard, but were too quick for me, I’ve added two photos taken in previous years and two by  gifted local photographers, Joan and Bob Bonin.  Thank you to Joan, Bob and Tom!

OUT AND ABOUT IN OAKLAND: Elusive Warblers and Summer Visitors

Hickory Lane at Cranberry_edited-1
Birding Group on a lane of Shagbark Hickory trees at Cranberry Lake Park

In the spring, when the leafing trees are full of warblers, it sure helps to have a birding group like our Wednesday Morning Bird Walks to provide trained ears and 14 eyes (or so) instead of just my 2!   Migrating birds ride south winds into our parks on their way north, with most birds moving through in April and May.  These temporary guests are small and move quickly about in brush or high in the trees.  Some birders, like Ben and our fellow birders, Antonio and Mark, can tell us which birds we’re hearing or they spot small movements in the treetops and show us where to point our binoculars.

In the last two weeks, I went looking for warblers and other avian visitors at  Cranberry Lake and Charles Ilsley  Parks.  Some are just passing through, some spending the summer.

As an amateur photographer, it’s a challenge to get decent pictures of these tiny, fast-moving bird guests, so please,  click on red links in this blog to see, or in some cases hear, birds that eluded my camera.  They’re beautifully diverse.  Who knows? Maybe you’ll recognize them in your yard or on your next walk.

Warblers  and Others Just Passing Through

According to Wikipedia,  English-speaking Europeans refer to their warblers, sparrows, and other small birds as “LBJ’s, ” meaning “little brown jobs.”  I used to ignore our “LBJ’s” thinking they were “just sparrows.” Turns out, sparrows can be beautiful too!  And our warblers here in North America come in all sorts of subtle colors, especially in the spring when they’re dressed for courting.  Here’s a beautiful Chestnut-sided Warbler (Setophaga pensylvanica) that the birding group saw at Cranberry Lake Park.

Chestnut-sided Warbler 3

During the winter, this little male hung out with tropical warblers in the Caribbean or Central America.  After traveling so far, it’s no wonder he needed to stock up on food and rest on his way to breeding grounds farther north.

We spotted the  Northern Parula  warbler (Setophaga americana),  but it just wouldn’t come out for my camera. Even Cornell Lab’s photo doesn’t do it justice, because its gray is much bluer in morning light and its back has a green patch – plus those rusty stripes on a golden throat! (Look at “Field Marks” lower on the page for a better shot.)  No LBJ, I’d say!

We heard the “squeaky wheel” call of the Black-and-white Warbler (Mniotilta varia) before we saw this little bird. It creeps along the bark like a nuthatch looking for insects. What a snappy dresser in those bold pin-stripe feathers! Listen to him here at “Typical Voice” about halfway down the page.

The Black-and-white Warbler moves like a nuthatch along branches.

For a bit of warm sunshine on a gray day, listen for the Yellow Warbler (Setophaga petechia). The male’s quick song , recorded at Cranberry Lake Park by Antonio Xeira and posted on the Xeno-Cantu site, sounds to some folks like a repetition of “Sweet, sweet, I’m a little sweet!”   – very appropriate for this bright yellow bird with a rusty-striped breast. Yellow warblers can be found in wetlands in our parks throughout the summer.

The Nashville Warbler (Oreothlypis ruficapilla) isn’t quite as glamorous but it’s definitely not an LBJ.  These small birds with their eye rings, gray backs and yellow breasts travel north to pine forests where they make their nests out of moss, bark and pine needles, or sometimes, according to the Cornell Lab, even porcupine quills!  Here’s a photo I took of one at Bear Creek last fall.

The Nashville Warbler travels farther north and makes a nest of moss, bark and pine needles.

The modest Tennessee Warbler (Oreothlypis peregrina) looks much more subdued.  Both were named for the place they were first sighted and both stopped at Cranberry  Lake Park this spring.

Ben heard or saw some other warblers in the two parks that I haven’t seen this spring. Have a look at the Blue-winged Warbler (Vermivora cyanoptera), seen at both Cranberry Lake and Ilsley Parks, whose wings look gray in some light (as in the photo) and blue/gray at other times.  Or the Black-throated Green Warbler, an olive-green bird with a black throat and black stripes down the side of its breast.  Ben always identifies this warbler by its buzzing call, which some folks describe as “zoo-zee, zoo,zoo, zee.” Listen here for the insect-like call (middle of page under “Typical Voice.”).   The Magnolia Warbler  (Setophaga magnolia), with its bright yellow head and  black-striped breast, also stopped by Cranberry Lake Park.  Isn’t it great that our parks provide food and rest for these little travelers ?

Even our sparrow visitors are not just LBJ’s!  Have a look at the boldly striped cap of this White-crowned Sparrow(Zonotrichia leucophrys)at Charles Ilsley Park.  In the second photo, he’s munching off dandelion seeds.  See, those puffs in your lawn are food to some of our avian visitors!

 

Guests That Spend the Summer With Us

The parks are filling, as well, with migrating birds that come to our parks to nest and raise their young.  One of the smallest (and hardest to photograph) is one that I think should be called “The Bandit Bird.”  But unfortunately,  this warbler’s name is the Common Yellowthroat (Geothlypis trichas), another bright yellow bird, but this little bird has a black mask across its eyes.  Like any good bandit, the Yellowthroat skulks in tangled vines and branches often near marshy areas.  The males, though, give their presence away with a very distinctive call of “Witchety, witchety, witchety” as heard here in Antonio’s recording. (Click on images to enlarge; hover cursor for captions.)

Some larger summer guests have arrived in the parks, as well.  We saw an Indigo Bunting (Passerina cyanea) at Cranberry Lake but it was down in the grass near the parking lot – so here’s a previous spring’s photo from Bear Creek.

Ben and some other birders saw a Scarlet Tanager (Piranga olivacea)at Cranberry Lake before I arrived – drat!  But here’s a photo from a previous spring at Bear Creek.  This  beautiful bird traveled all the way from South America just to raise young here in Oakland Township.

The nesting boxes are busy at Charles Ilsley Park.  Here a Tree Swallow (Tachycineta bicolor) stands guard at one of them.

Nearby, its Eastern Bluebird neighbor, who may have stuck around all winter or arrived much earlier in the year, was out plucking what looks like a caterpillar from a plant and delivering to his presumably nesting mate.

The glorious Baltimore Orioles were in both parks that I visited.  The male’s pure, high whistle can be heard high in the treetops as he and his mate search for a spot, usually near water, to weave its bag-like nest that will rock its young in the wind.

Time and Migration Wait for No Man…or Woman Either!

The rolling slopes of Ilsley Park, with its golden dandelion-strewn paths, await!  If you can spare the time, join the Wednesday morning bird walks listed under the Stewardship Events tab above.  Ben will provide binoculars and his expertise  and the easy-going birders will welcome you.  So will the glorious avian visitors either enjoying a little R&R before moving on or settling in to raise a family.  But many of the warblers will only be here a few more days.  So come have a look!
