Songs and Flashy Colors

A male Ruby-crowned Kinglet flashes his bright red feathers atop his head as a warning to other kinglets to stay out of his territory.

April 30, 2020 – The season of new growth and flowery fragrant blooms brings fresh songs and flashy colors, as migrating warblers and Kinglets show up in the thickets and along the brambly prairie edges. Busily feeding, while taking little time to preen or rest, some of these travelers have reached their summer nesting areas while other birds still have miles to go and are loading up on insects and worms while at this bountiful northbound sojourn. On some days these temporary stops can be very busy places with many species of birds. Some are here the year around, like the bright red singing male Cardinal calling out to a female and bringing her seeds as she glides in and perches nearby. A Brown thrasher, a short-distance migrant that winters from the tip of Southern Illinois and all of the Southeastern United States, has arrived. It is hard to miss this large songbird with its’ bright yellow eyes and impressive chisel-like bill and long tail feathers. Often seen perched and singing its’ many songs, a faceted repertoire of melodious lyric that sounds as if there are five or six other birds making those rich notes, the Brown thrasher without a doubt is an inspiration and an uplifting treat to the senses. The shadowy places beneath overgrown bushes and briers are the hunting grounds for the Hermit thrush. The little brown bird, with a spotted breast, and large dark eyes, adorned with distinct white eye-rings, is a secretive bird that may be watching you before you ever notice it. The sparrow sized bird is occasionally revealed as it moves through the broken sunlight that has illuminated the fallen limbs and leaf litter in the small open areas below the thick understory. Scratching the litter as it looks for insects, the little thrush eventually disappears from sight as it continues its’ ground level hunt though the woody labyrinth. Ruby-crowned kinglets are busy in the trees and bushes searching for insects. These tiny birds are on their way north to northern Wisconsin and on into Canada for the nesting season. A male kinglet has lay claim to some nearby bushes and the branches in a tree about ten feet above the ground that he is aggressively guarding and will not allow any other kinglets to come near. When an intruder comes too close, the little male quickly swoops in showing his fiery red feathers on top of his head, that are normally flat and almost hidden. That blazing red flashy plumage, that is only erect for a few seconds, is standing straight up in a threatening display as he chases the other birds away from his claimed hunting spot. Soon more colors will arrive with the warm southern winds, some of these birds will stay, and some will continue north and for the lucky observers there will be those less often seen warblers, those mysterious neotropical beauties that are sure to touch ones heart with only a momentary glimpse that leaves a lasting impression as they pass through on their way north.

Shorebirds Stopping by

April 16, 2020 – When the spring rains create temporary flooded pools in the agricultural fields, pastures, and on the low well saturated land of restored prairies here in Northern Illinois, the migratory shorebirds large and small will show-up tired and hungry. A variety of shorebird species are working their way across Illinois this time of year. These birds must feed and rest and sometimes wait for the right weather conditions as they instinctively know when to continue the push north. The mudflat-like edges surrounding the flooded slow draining areas in the fields are the perfect habitat where these birds can find the tiny worms, mollusks, and insects that are important to rebuild their depleted energy. Building up fat reserves and resting is key to the survival for both medium and long distance migrants as they pass through on their challenging springtime journey, moving to their northern summer nesting areas. Many of the shorebirds travel great distances to reach their nesting areas on the high Arctic tundra. Pectoral Sandpipers spend the winter on the wetlands and agricultural areas of South America but they nest many thousands of miles north on the sometimes cold springtime Arctic tundra. Here in Illinois we see many flocks, some quite large, of the Pectoral sandpipers using the flooded fields to rest and feed as they work their way north. The sandpipers stay together in and around the flooded wet spots feeding, preening and occasionally taking to the air when a bird of prey comes too close. Flying in a tight pattern the birds circle back and forth until all is clear and then quickly return to the same wet spot to continue their feeding. The much larger Greater Yellowlegs has longer legs than the Pectoral Sandpiper and are often in deeper water searching for prey. The Greater Yellowlegs migrates a shorter distance than the Pectoral. They spend the winter on the Atlantic coast, the Gulf coast, Florida, Mexico, Central and South America. The Greater Yellowlegs nest across Canada just south of Arctic Circle and on the coastal areas of Southwestern Alaska. Those are just two species that are fairly easy to identify during the northern movement, there are many others to watch for in these short-lived shallow pools that temporarily linger in the fields. Some of these shorebirds are quite small, others are in their impressive breeding plumage, sometimes there are rare species, but one thing is for sure they all are in need of food and rest as they still have many miles ahead.

An American Robin eyeing a dried red berry from last years’ crop before plucking it off and continuing its’ hunt

April 2, 2020 – There is nothing that alerts us to a change of the seasons more than those early morning songs of the American Robin. The Robin has a strong, rich whistle that begins to invade our dreams not long before the glow of first light. This medium sized, orange breasted, dark headed bird with a bright yellow bill is probably one of the most familiar and common birds we see. The Robin likely draws attention more often than other species as it runs, stops, and probes the grassy spring and summer lawns here in the Midwest searching for earthworms large and small. Although there are Robins in our area of Northeastern Illinois year round, they are more often seen in their winter flocks in our rural areas where there is plenty of food like wild fruits and berries along with thick cover that can protect them from harsh cold weather and dangerous predators. Even though many Robins remain in our natural areas throughout the cold months, some do migrate. The springtime brings a behavioral change to the wintering birds as the large winter flocks break-up into small flocks dispersing from their winter habitat. The birds become more territorial and we begin to see those Robins in our city parks and on our grassy lawns as worms become a warm weather food source and nesting sites are the focus. Soon there will be nesting Robins everywhere, the female will be sitting on her perfectly constructed nest made of sticks, grass, and mud keeping her three to five sky blue colored eggs warm for about fourteen days. Robins are good at putting their nests in some of the most inconvenient places, like above exterior doors, below eaves, on gutters and electrical services, and sometimes in trees. The American Robin may have up to three broods in one season and the female and the young join the males in the roosts after the last brood is fledged and the nesting season ends. As cold weather once again approaches and the ground freezes and the worms are gone, the American Robin will rejoin the winter flocks where fruits and berries will become an important food source for the coming months.

Spring Has Arrived

A Snowy owl perched in the morning sun this past week in Iroquois county will soon feel the urge to head north towards the vast Arctic Tundra for the summer

March 26, 2020 – Looking out across empty agricultural fields separated by waterways of dried grasses, flowing ditches, fallen fences, and the occasional leafless trees in the small and forgotten gnarly thickets that have somehow been spared the plow, we bear witness to a season in change. The picture before us speaks of a tired and somber late winter that is ready to give up its’ frail but respected hold to a new, strong, and hopeful spring. The spring migration brings temporary visitors that are working their way northward, while wintering birds are gathering and waiting for that call to move north. Some of our resident birds of prey, like Bald eagles, Great Horned owls, and Red-railed hawks, in Northeastern Illinois are already nesting, and some are tending to young. The feathered travelers, those long-distance migrants from the southern hemisphere, are yet to arrive but will stage in our area in the coming weeks resting and feeding before continuing north. Others are patiently waiting for those longer warmer days before moving north towards the high latitudes and a short nesting season above the Arctic Circle. Rough-legged hawks, Snowy owls, and American Tree sparrows are some of the birds that have some distance to travel, and in a month or so, those birds will be hard to find as they eventually disappear from the Lower Forty-eight for the summer. This past week two Snowy owls, only a few miles apart, continued their presence in Iroquois county. A dark morph Rough-legged hawk, another wintering Arctic bird, was hovering over a field hunting in the same area not far from one of the owls. On the first day of spring nine Trumpeter swans could be seen resting in some corn stubble east of the Iroquois river, these great white birds will soon move north into the marshlands of Michigan,Wisconsin, and Minnesota for the nesting season. A small flock of American Tree sparrows have been taking advantage of the remaining seeds on an overgrown lot south of Kankakee while finding safety and insects among the web of thick overgrown bushes and small trees. Spring has certainly arrived and the migration brings hope for new generations of many species and a promise of stability for all creatures on this little planet.

White-breasted Nuthatch

A female White-breasted nuthatch pauses for a moment on a branch, the chestnut color below the tail is clearly visible.

February 20, 2020 – The big raspy voice of the little White-breasted nuthatch is a familiar sound in the winter woods of Illinois. Throughout the softly illuminated and leafless winter forest, or at a busy backyard feeder, it is easy to spot those colorful little hunters as they noisily swoop in. Suddenly there is a flash of blue-gray, then another, and yet another as four, maybe more of those regal looking little birds appear. A male and a female nuthatch light on the patchwork bark of a large sycamore and quickly begin searching tree and limb for food. The little birds move up and down the trunk like acrobats as they move head first down the tree searching the nooks and crannies for insects. Not long after the small winter flock of White-breasted nuthatches appear, their songs begin to fade into the distance as they continue their search for food on the trees and shrubs along an overgrown and abandoned road that the woods has mostly reclaimed. The White-breasted nuthatch is common across most of the United States and is a year-round resident here in Illinois. The male nuthatch has a dark black cap, white face and underparts with splashes of chestnut colors under the tail. Their wings and back are mostly blue-gray. The little birds have large heads, large feet, and a long pointy bill. The female looks pretty much like the male nuthatch except they have more of a gray colored cap with stronger chestnut coloring near their rear under the tail and their overall colors are a bit weaker than the male. The nuthatches eat nuts, acorns, insects and cache food items around their territory. You may find the winter flocks of nuthatches mixed with chickadees and woodpeckers.

The Pigeon Hawk

Just east of Kankakee recently, a Merlin falcon looks down from its’ tree perch watching for an ambush opportunity.

January 23, 2010 – The Merlin falcon is a small but fierce hunter that is a little larger and heavier than the American kestrel. Looking somewhat like a chunky pigeon in flight the Merlin was once known as the pigeon hawk. The stealthy falcon lacks the bold color patterns and black “mustache” that adorns the face of the more common Kestrel. The Merlin’s may show a faint “mustache”, the black plumage on the sides of the face, but the bird appears a bit drab overall compared to the smaller and more colorful Kestrel. The female Merlin, like other birds of prey, is larger than the male. A large female with a recent catch of a small bird was facing away from me as it sat on a roadway in Iroquois county a few years back. From a distance the bird looked like a small Peregrine falcon, its’ solid blue-gray back and wings stood out and its’ thick body confused me at first until the bird took to the air with its’ prey. At that point I recognized it as a Merlin. The little Merlin is an avian hunting master that can send a flock of birds into a mass of fear and confusion. Outmaneuvering the unfortunate winged victims like Starlings, Sparrows and even small ducks, the Merlin,with a swift and precise attack snags its’ targeted prey while in flight. It also plucks dragonflies and other insects out of midair during its’ migration for a quick and easy snack. If you are fortunate enough to see a Merlin in our area of Northeastern Illinois it will most likely be during the winter months but sightings of the Merlin are becoming more common as the population of the little falcon has improved. The Merlin is known to breed in the boreal forests of the north but the discovery of a hatchling on the ground in Northwestern Cook county in 2016 may signify that they are expanding their breeding range.

The Brown Creeper

A Brown creeper probes with its’ long curved bill behind the bark of a tree looking for insects.

January 1, 2020 – The Brown Creeper is a tiny well camouflaged bird that seems to defy the forces of nature as it swiftly moves across the jagged edged bark of a tree. It pauses momentarily to search, with its’ long curved bill, the cracks and openings in and behind the tree bark for insects. The bird is an expert contortionist twisting its’ head to just the right angle to probe the difficult fissures to find its’ unsuspecting prey. The fast moving little Brown creeper, also searches the undersides of large limbs and is probably less often noticed by humans due to its’ size and dark colors than any other species of bird that spends as much time in the trees. The little bird blends in quite well to the tree bark of the large dark trees on which it hunts. The Brown creeper will land low on the trunk of a tree and work its’ way up and around the trunk eventually searching the higher branches for prey before moving to another tree. From my observations at multiple locations while watching the tiny creeper, within a short time of leaving one tree it will return back to the same tree repeating its’ search several times before moving on to continue its’ hunt on other trees. According to the Illinois Natural History Survey “the Brown creeper occurs in Illinois as a common migrant and winter resident and occasional summer resident. The Cache, Kankakee, Mississippi, Sangamon and Sugar Rivers appeared (1981) to be the center of distribution for nesting populations in Illinois.” Known as a short-distance migrant to resident we notice the wintering birds that have arrived in numbers from the north when we notice them hunting on the leafless trees in wooded areas and on the parameters of those timbered tracts of land.

White-winged Dove

April 17, 2019 – There was quite a surprise out my kitchen window last week in the late afternoon on Wednesday the 17th. Standing on a branch in a tree where I have a number of bird feeders was an unusual visitor from the Southwestern United States, a White-winged dove. The white wing patches were clearly visible when I first sighted the bird and I immediately knew what it was. Even though they are occasionally seen in Illinois since the first record in 1998, they are listed by the Illinois Ornithology Society as a casual and they are posted on eBirds Illinois Rare Bird Alert when there is a sighting. The dove is more than likely a first record for Kankakee county. White-winged doves live year-round in the Baja California peninsula, southern Arizona, southern New Mexico and southwestern Texas. They are in most of Mexico down into Central America east from the Yucatan peninsula, Cuba, Puerto Rico and the Bahamas. By the time I retrieved my camera the dove had laid down on the limb and was facing away. I was never able to photograph the white on the wings.

Turkey Vultures

April 18, 2019 – As springtime advances and the migrants move north, Turkey vultures, those masters of the air currents, are once again gliding across the skies of Northern Illinois in large circling flocks that are sometimes referred to as a kettle. Even though a few of these large dark colored vultures are spotted in northern Illinois during the winter months, most migrate south in the fall after the nesting season. They spend the winter from Southern Illinois and across the southern United States, south through Cuba, Mexico, Central and South America and as far south as ‘the end of the world’ Tierra del Fuego in southern Chile.

North America has three of the six subspecies of Turkey vultures. Cathartes aura septentrionalis is found in the eastern United States.(Palmer, 1988) With a wingspan of around six feet these large slow flying birds are hard to miss as they fly off of the carcass of the unfortunate roadkill as a vehicle approaches. Those close encounters certainly gives the observer an appreciation for the impressive size of the Turkey vulture. They usually don’t go far when flushed from the carrion and soon return to their feeding when the threat is gone. They are often seen still on their roosts in dead trees, utility poles or buildings early in the morning. With their wings spread wide like a parabolic antenna while facing the warm morning sun they are warming their bodies and drying their feathers from a rain shower or the dampness of the night.

Nesting Turkey vultures will use the abandoned nest of other large avian species in secluded areas far from human traffic. They will also use old sheds, barns, and houses that are remote, grown-up, neglected and open to the elements. The Turkey vulture may choose to lay their clutch of 1 to 3 eggs in a nest on the ground that they scrap out in the leaf litter in a dense thicket or near a fallen tree or even in a hollow log. The vultures will have only one brood over a 60-84 day nesting period and may return to the same nest year-after-year according to The Cornell Lab of Ornithology, All About Birds. Palmer, R. 1988.

White-winged Scoter

February 16, 2019 – Considered a sea duck, White-winged Scoters are observed in numbers primarily along the coastal areas of the US and Canada. They winter along the coastlines from Baja California to the Aleutian Islands in the North Pacific and along the coastal areas of the south and eastern US from the Gulf of Mexico north to the Canadian Maritimes. According to The Cornell Lab of Ornithology online resource, All About Birds, “Although the White-winged Scoter winters primarily along the coasts, small numbers winter on the eastern Great Lakes.”

A solitary bird or just a few are often recorded inland on ice free open areas of lakes and rivers during late winter in Illinois. Higher numbers of scoters will be found across the area of the Great Lakes north into Canada on the migratory staging areas of late winter and early spring as they push towards those summer nesting grounds in the central Canadian provinces, Northwest Territories, and north into central and northern Alaska.

Over the years Jed Hertz has recorded a number of White-winged Scoters on the Kankakee river. This year is no exception. On January 2nd , below the dam near Jeffers park, Hertz spotted a single White-winged Scoter. On Monday February 11th Jed again found a duck that could actually be the same scoter on the river east of Aroma Park. Photos allow for a closer look of the scoter and it appears to be an immature drake. Jed notified me and I was able to get a few shots of the duck as it worked on an aquatic plant stem, biting and chewing it between its’ thick bill, possibly trying to remove a larvae from the hollow parts of the segmented stem.

White-winged Scoters are a diving duck that feed mainly on mollusks. In wintering areas, crustaceans are an import food source. Scoters have a unique ability to use their wings and feet to propel quickly to the bottom. I observed this behavior from my vantage while watching three scoters feeding near 4th avenue in Kankakee in January of 2014. When they began their head first dive their wings became partially opened and used as if in flight as they disappeared into the depths. A science journal article called “Costs of diving by wing and foot propulsion in a sea duck, the white-winged scoter”, states that, “Most birds swim underwater by either feet alone or wings alone, but some sea ducks often use both.”, perhaps an adaptation required for deep water dives. ”Scoters using wings + feet had 13% shorter descent duration, 18% faster descent speed, 31% fewer strokes/m, and 59% longer bottom duration than with feet only.” J Comp Physiol B. 2008 Mar;178(3):321-32.
