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.
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.
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.
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.
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.
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.

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.

February 5, 2019 – Last weeks little bit of open water on the river at Cobb park was a gathering place for a few hundred Canada geese. A number of ducks, both divers and dabblers, swam, rested, and hunted the open water between the ice while at times disappearing into those dark cold winter pools of the Kankakee river only to reemerge a short time later with their catch. A single Tundra Swan, larger than the Canada geese that surrounded it, stood-out with its’ bright white feathers and elegant presence. The Tundra Swan is a visitor seen during the winter months or during migration on the open waters of large lakes, rivers, and in grain fields in the northern parts of the US. During the nesting season the Tundra Swan, sometimes called the Whistling Swan because of the sounds emitted from their wingbeats as they fly, are on their breeding grounds in the remote wetlands of the high Arctic. There are only two native species of swans in North America, the Tundra and the Trumpeter. The Trumpeter swan is slightly larger than the Tundra and for the observer it sometimes requires a close look to determine which species you are looking at.
February 5, 2019 – The cold weather has brought the winter waterfowl to the open icy waters of the Kankakee river. Common Goldeneye, Common Mergansers, Redheads, Canvasback ducks and more can be seen feeding and resting below the dam near Jeffers park in Kankakee. Jed Hertz spotted a White-winged Scoter this past Saturday, the Scoter is a rare visitor that is usually seen during the winter months on the Great lakes and the coastal areas of the United States and Canada. In one photo a male Canvasback duck is swimming with two male Redheads, look close, they are very similar species. The other photo shows a male Canvasback and a female that appears to be sleeping, don’t let her fool you, she is quite alert as she floats along the icy shore of the Kankakee river.
The Common Goldeneye ducks fly up river towards the dam and land near the Washington Street bridge where they begin diving for crayfish as the current takes them back down river, a process that is repeated over-and-over again. The Common Mergansers do the same thing, catching small catfish, bass and shad. Ring-billed and Herring gulls swoop in to steal the prey from the ducks as soon as they surface with their catch. Mallard ducks, Greater Scaup, Lesser Scaup and the American Black duck can also be seen down river from the dam.
November 12, 2018 – A large 12 point buck, photographed just west of Kankakee recently, displays those tell tale signs that the breeding season for White-tailed deer is occurring in our area. Also known as the “rut”, the mating season for the White-tails really gets in gear by the end of October and lasts through January. This burly buck with his huge swollen neck stands like a stone fence between the doe and the intruder. The explanation for the enlarged necks on White-tailed bucks this time of the year during rut is widely believed by wildlife biologists to be the affects of a surge of the testosterone hormone. The increase in hormones is also believed to cause the aggression and the lack of fear that is a well known behavior of the White-tailed buck during the rut.
