Red-Red-tailed Hawk

December 17, 2020 – It seems that one cannot travel more than half-a-mile without noticing a large hawk perched on a utility pole, or on a barn, or a corn crib, often two birds within a short distance of each other, many times even on the same branch of a large tree overlooking a good hunting area. Once known as the “chicken hawk” and blamed for missing poultry, Red-tailed hawks were shot on a regular basis whether they were guilty or not. These great raptors are now protected under the federal Migratory Bird Treaty Act. Red-tailed hawks hunt a variety of prey, from rabbits, squirrels, pheasants, mice, and voles to insects and snakes and even carrion. They have a varied menu of prey to chose from. These hawks hunt and nest not just in the rural countryside but also in populated areas of towns and cities. They are very adaptable and where there are some tall trees, open spaces, and prey to be had, Red-tailed hawks will be found. These large hawks are very territorial and vigorously defend their nesting trees, hunting perches, and the surrounding area. With a four foot wingspan and their well known screaming vocalizations, they can be quite intimidating to other birds of prey that enter their territory. It is not uncommon to see Red-tailed hawks chasing and attacking other large hawks that have drifted into their space. The mostly pale plumage on the chest and belly of a Red-tailed hawk is easily visible when contrasted against the dark leafless trees of winter. Even at some distance you can, with good confidence, ID these large birds-of-prey. Red-tailed hawks are quite common across the United States and are here the year-round in Illinois. The numbers of Red-tailed hawks does increase in the fall as the northern breeders move south for the winter to escape the harsh conditions across Canada and Alaska.

Rough-legged Hawk

December 10, 2020 – Early December brings us some crystal clear and cold nights under brilliant waning moonlight that seems to sparkle on the frosty panes of thin ice forming on the creeks and along the river’s edge. The low temperatures create icy patterns that surround the many exposed and weathered rocks in the shallows with delicate chilly collars that will soon grow into thick cold locks that will hold fast in the coming weeks. These cold months also bring those Arctic hawks that will spend the winter hunting the prairies and farm fields here in the Midwest. The Rough-legged hawk’s diet has changed from the Lemmings of the Arctic tundra to the small mammals, like mice and voles, found here in our area of Northeastern Illinois and Northwestern Indiana. During the nesting season in the high Arctic the Rough-legged hawks use rock ledges to build their nest in the vast and remote land of the midnight sun. While on their winter range, if they are not hovering or kiting over the grassy prairies and fields searching for prey, the hawks can be seen perched on the small branches in the tops of trees, or on utility poles and fence posts near a good hunting area. Like Snowy owls and other predators that migrate south out of the Arctic, the years of abundance in prey, especially Lemmings, means an increase in the predictors population, and an increase in numbers of migrants that winter here in the lower 48. The Rough-legged hawk is one of three raptors that have feathers down it’s legs to the tops of its feet, certainly an adaptation for colder conditions of the unpredictable Arctic. Watch for the Rough-legged hawks perched or gliding into wind above the prairies throughout the winter and keep in mind there are light and dark-morphs, some are quite dark and some have very light plumage. They have small feet with feathers on their legs that can easily be seen with binoculars.

The Common Redpoll

November 19, 2020 – As we ease through the chilly days of November, the leafless trees and frosty mornings remind us of the coming winter as do the new arrivals of Arctic birds that we now see in flocks great and small in our rural areas of Northeastern Illinois. Snow buntings and Lapland longspurs are now feeding along the gravel roads and in the harvested fields of Kankakee and Iroquois counties. This year also seems to be a year where some other species of birds that normally winter a bit further north, have come south into Illinois in larger numbers. The Pine Siskins are here in large numbers, Red Crossbills, and White-winged Crossbills are being seen in the Chicago area, and even a few places south. Another little bird that has a more northern winter range, that I had the pleasure of seeing in Iroquois County this past week, is the Common redpoll. A number of reported sightings of redpolls continue to come in for Northern Illinois, one reported sighting of a flock of 15. This little finch, the Common redpoll, breeds in the Arctic and sub-Arctic regions and winters across the Provinces of Canada and south into the area of the Great Lakes. They are about the same size as the Pine siskin with similar markings but lighter overall. The male redpoll has a beautiful red crown with some rosy-pink color on the chest, and dark streaks on its underparts. The female is a bit duller overall, and lacks the pink-washed color on the chest, but does have the red feathers on the head, the red poll. The bright yellow bill of the redpoll is made for eating seeds, it is small and pointed for getting to those tiny seeds of the birch, alder, and willow trees. The sighting last week in Iroquois County was of a single male Common redpoll in the company of a small flock of House finches that were feeding on some ripe wild berries on the sunny side of a thicket. It was an exciting treat to observe this little Arctic breeder in a rural area of Illinois.

Puffed up after preening, the lovely colors of red, yellow, gray, and brown show the amazing beauty of the Common redpoll.

White-throated Sparrow

Perched in the morning sunlight the bold beautiful markings on the face and throat of the White-throated sparrow standout.

November 5, 2020 – Back in Illinois for the winter months are the White-throated sparrows, a large and attractive bird with a long tail and a bright-white throat and bold face patterns of black, white, gray, and yellow. The White-throated sparrows are considered a short to medium-distance migrant. It breeds in the United States in the Upper Great Lake region and in the coniferous and mixed forests across most of Canada. There are small pockets of year around birds in the northeast U.S. The sparrows leave the impending harsh winter of the north in autumn before the first snow and head south into the United States to a more hospitable climate that is not totally locked in ice during those cold months. They appear in northeastern Illinois about the same time in the fall each year as many other sparrows, like the White-crowned, Lincoln’s, and Swamp sparrows. Similar to the Fox sparrow, the White-throated sparrows forage on the ground under the thick gnarly cover of the shadowed understory kicking leaf litter with its feet searching for insects, seeds and fruit in a very focused but alert manner. The sparrow can be found near heavily vegetated areas around parks and near rivers and creeks where there is plenty of cover. Also, during prolonged snow cover, many birds, including the White-throated sparrow, can be found in the windswept areas along roads and in fields searching for seeds. The White-throated sparrows will show up at backyard feeders during the winter here in Illinois with other birds providing there is some good cover nearby. Backyard feeders are favorite haunts for predators like Cooper’s hawk, domestic and feral cats, so quick escapes into thickets, bushes, and trees are a necessary part of a safe habitat for feeding birds.

The Tufted Titmouse

Paused for only a moment, a Tufted titmouse quickly leaves its’ perch and disappears as it continues its’ search for a nice large seed.

October 29, 2020 – It is late October and the unmistakable and lovely echoing song of the Tufted titmouse, a small gray songbird with large black eyes, is in the air. Four of the fine-looking little birds descend to the ground to search through the leaf litter for fallen seeds. After finding a large seed, the titmouse quickly flies up to a branch and holds the seed between its’ feet and hammers away on the food with its’ bill to break the seed into smaller, edible pieces The Tufted titmouse is a common year-round resident to the eastern forests of the United States, most often seen during the fall and winter months at backyard feeders, parks, and open brushy areas at the edges of wooded landscapes where fruits, seeds, and insects are available. Northern Illinois, and states east to the Atlantic, are at the northern edge of the little birds’ range, although surveys have shown that they have been expanding their range northward as far as southern Canada for sometime, possibly due to a warming climate and the fact that more people are feeding birds during the winter. With a gray crest, dark forehead, a stubby black bill, and rusty colored flanks with white underparts the little Tufted titmouse stands out against the dull shades of brown on the autumn landscape, much like its’ smaller cousin, the Chickadee, with its’ bright crisp colors. It’s a speedy little bird that can suddenly appear, sometimes in a banditry of three or four bold little titmice, where there is a good food source. Cautiously but quickly the titmouse hops from branch to branch and then to the ground, many times chasing other birds away, finding a large seed to either eat now or take away and cache for later. The Tufted titmouse is a joy to see and a treat to hear, somehow their beauty is enhanced when snow comes to the woods. Maybe it’s the soft illumination from the blanket of white under the stark winter sky or just bottled up nostalgia that seems ready to burst with each new encounter.

Winter Is Coming

Young White-tailed bucks spar on a grassy hill as the deer breeding season nears.

October 22, 2020 – The cool temperatures of the Midwestern autumn bring a patchwork of awe-inspiring colors to both rural and urban landscapes. Reflections of the changing season fill the rivers, lakes, and slow flowing creeks that meander across the weary prairies and through the used-up pastures with a wonderful palette enhanced by the defused light of the gray autumn sky. The greens of the summer foliage are slowly disappearing into a changing landscape of late October. Large flocks of Turkey vultures, sometimes 40 or more, can be seen gliding in the breezy sky slowly working their way south for the winter. Some of the vultures are high in the sky with wings swept as they cut through the strong winds, others are gliding low across the tree tops and fields making progress working to windward across a gentle rolling sea of color. Winter flocks of black birds flying in unison take to the air from a fencerow as a Cooper’s hawk moves towards the mesmerizing display for a short pursuit that ends quickly as the hawk gives up on the evasive murmuration. Numbers of Pine siskins are seen in large and small flocks in the same areas where Gold finches in their drab winter plumage are feeding. The Pine siskin is a bird of the north that feeds on the seeds of coniferous and deciduous trees, though some years they move south in greater numbers if the seed crop of the north is poor. While fattening up on the available food the thick furred Fox squirrels are busy building their caches for the coming months. Young White-tailed bucks still in their bachelor group spar with each other on the sunny side of a sandy rise. As the rut grows near, these bucks will grow less tolerant of each other and the sparring will become much more serious, the group will break up and the bucks will go off on their own. Soon breeding will be the only thing on their mind as they search far and wide for does. A cold clear starry night accompanied by a freeze warning to gardeners and farmers tell the tale of no return, winter is coming, and that swift moving stream of the cold north winds will bring ice and blowing snow in the coming weeks. The frigged deep freeze of winter that is brought to use by the dynamics of a tilting planet will soon be at the door.

The Magnolia Warbler

A Magnolia warbler stops for just a moment as it forages through the bushes looking for insects.

October 1, 2020 – The Magnolia warbler is a small songbird that nests across the provinces of Canada, from British Colombia, to Nova Scotia, and the Upper Great Lakes, to the northeastern US. The warblers have striking colors even after the breeding season, when many birds lose their bold colorful plumage and become rather dull. During the fall migration these little warblers bring some bright yellows to the early autumn Midwestern woods. These long-distance Neotropical migrants are on their way south stopping for a few days in a small woods in Iroquois County. Suddenly appearing out of the thicket, the Magnolia warblers forage for insects through the leafy bushes at the sunny edge of the small wooded area no larger then an acre. These small patches of land that have for some reason avoided the plow are life savers for migrating birds, insects, and bats. Whether seasonal migrants, or wildlife that is here year around, these small untouched habitats that are few and far between, and barely surviving among the cultivated lands of Illinois are pieces of land that are of the utmost importance to many species. The loss of habitat at wintering and nesting sites as well as the food and resting areas along the migratory routes can have a devastating impact on many species of birds. The Magnolia warblers travel from Panama and Mexico to the far northern US and up into Canada and back again in the fall. These migratory trips can be as much as 4000 miles one way. It is a hard trip for the little fliers and those exhausted birds that can’t find places to rest and feed don’t make it. Awareness and conservation are key to help prevent many species of birds from being listed as rare, or worse, cannot be found. Shade coffee farms that are replacing the sun coffee farms have provided good habitat for the warblers, Hummingbirds, and other species, and supporting shade grown coffee goes a long way in helping provide a winter habitat for these migrants. River valleys, lakes, and the islands of uncut forests across Illinois are the refueling stations for these tired night travelers that still have many miles to go during another exhausting and challenging migration.

The Cape May Warbler

September 24, 2020 – The Cape May warbler winters in the West Indies and breeds in the boreal forests of the northern border states from Minnesota east to Maine, and north into southern Canada, from Quebec west to Alberta, and into the southern edge of the Northwest Territories. These warblers are highly dependent on the spruce budworms as a source of food, a good year for the budworms means a great year for the warblers. Those banner years for spruce budworms coincide with more fall sightings in places where the Cape May warblers are less often seen. Although the Cape May warblers specialize in the spruce budworms that are plentiful in their summer nesting areas, they also can take advantage of other sources of nourishment such as the nectar from flowering plants, and the juices from ripe fruits. Similar to hummingbirds, flowering nectar rich plants are an important source in their winter habitats as well during the fall migration. These warblers have a specialized tongue that is semi-tubular that allows them to lap up nectar with ease. They also can use their sharp, pointed bill to puncture the skins of fruits to get to those sweet sugary juices. The little warbler gets its name from Cape May, a county in New Jersey, where the species was first collected, not far from the coast in a maple swamp where George Ord, a zoologist, was on a collecting trip with the celebrated ornithologist Alexander Wilson in1812. There is more to this story about when the Cape May warbler may have actually been collected at a much earlier date, in the Caribbean in 1751, and named the Spotted Yellow Fly-catcher, but that’s another story and it seems the name Cape May has stuck. After discovering the species in Cape May, the next recorded sighting of the bird at that location would not happen for another 100 years.

The Cape May warbler that was perched on a branch in Kankakee recently gave a good side view that revealed some its’ less often seen markings.

Listen to the Mockingbird

A Northern Mockingbird perches for a moment as it searches for prey at the edge of a woods in Iroquois County.

August 6, 2020 – An always expanding collection of finely mimicked songs is the beautiful repertoire of the Northern Mockingbird. Both male and female mockingbirds have the amazing ability to vocalize the songs of many other birds and even some sounds found in nature that are not birds at all, like frogs for example. August 6, 2020 – Singing out with some impressive melodies, an effort meant to attract a mate during the spring and summer, the male mockingbird is a highly motivated and persistent melodious suitor. One cannot ever assume that they are hearing the strong rich songs of the Northern Cardinal, or the mysterious unearthly whine of a Gray Catbird, coming from the forest thicket when there is a talented mockingbird with it’s amazing ability in the area. Over the years the celebrated Northern Mockingbird has been, and continues to be, the inspiration for authors, poets, and lyricists as the subject of joy, sadness, or quiet reflection. The unmated bachelor mockingbird is relentless and will sing his desperate love songs late into the night, sometimes detouring their human neighbor from their coveted path to dreamland, causing some frustration for the tired. The disturbed half awake human, perched nearby, find themselves silently rooting for the bachelor’s quick success in finding a mate, an endeavor that would surely put an end to the late night concerts. The Northern Mockingbird is about the size of a Robin, it has a long tail, and is gray over white in color. The mockingbird has some distinct white wing patches and white in the tail that become obvious when the bird is in flight and their feathers are spread wide. The eyes of the mockingbird are light brownish-orange in color and appear quite striking in good light. Our area of Northern Illinois is in the northern edge of the mockingbirds year-round range but they are more common during the winter in the central and southern part of the state.

Southbound

A pair of Lesser Yellowlegs Sandpipers standing tall face to face having a dispute over the hunting area that will eventually lead to a noisy fight.

July 30, 2020 – This past week a number of early migrating shorebirds, on their southbound journey, had stopped at a flooded field in Iroquois County taking advantage of the available but temporary source of food. The largest of the shorebirds that was feeding at the shallow, slow draining, organism rich, field were the Greater Yellowlegs Sandpipers. The smallest birds were the Least and the Semipalmated Sandpipers. The Least, which is the smallest shorebird in the world, and Semipalmated Sandpipers searched for insects around the perimeters. The Greater and Lesser Yellowlegs with the longer bills and legs were wading through the deeper waters probing the soft mud below the surface with their long pointed bills searching and amazingly finding tiny insects and other invertebrates with their sensitive bills. While many of the species feeding in the flooded field get a bit aggressive when it comes to their hunting areas, quickly chasing away other birds that get too close, the Lesser Yellowlegs at this feeding site over a few days of observation seemed to only have conflicts with its’ own species. The Lesser Yellowlegs would fly, sometimes 50 feet, to challenge or chase away an intruder. Sometimes, though, the intruder would hold it’s ground and the excited birds would face off. Standing as tall as they could, bill to bill, making themselves appear large, the birds were certainly trying to intimidate each other. Suddenly, one would jump high into the air above the other coming down with it’s feet in the face of the other bird. With wings flapping, their bills and feet became weapons, the aggressive sounds of fighting sandpipers intensified, then suddenly they would stop. The birds would once again take that face to face bigger than life posture until one would attack. This squabble would happen four or five more times before they would slowly, but carefully, back away from each other and start feeding a short distance away widening the gap to a safe, tolerable, and perhaps agreed upon, distance. Most of the shorebirds were tolerable of each other with little aggression when hunting areas overlapped, at least they weren’t fighting like Lesser Yellowlegs who seemed to be looking for trouble. These shorebirds will work their way south to Gulf Coast, some going as far as South America where they will spend the winter until spring once again calls them north.
