Trumpeters in Kankakee County

Trumpeter swans seeking refuge in a flooded field in Kankakee County during migration to the northern wetlands.

April 8, 2021 – There were 18 beautiful Trumpeter swans, discovered by Iroquois County resident Rick Rosenboom, resting in a flooded field in southern Kankakee County in early March. Occasionally, one of the great birds among the resting flock would stretch and flap its impressively large wings, which for Trumpeters can span over 6 feet. The flocks’ stunning, bright-white feathers were illuminated by the afternoon light making these migrant travelers appear otherworldly against a drab late-winter landscape. The flooded spot, a low and almost hidden area in an agricultural field, gave the swans a safe place to sleep, preen, and forage for a short time before continuing their migration to a northern wetlands for the nesting season. The Trumpeter swan is the largest native waterfowl in North America. Female Trumpeters can weigh up to 25 pounds, and males up to 38 pounds. There is an obvious difference in size between the other native swan, the smaller Tundra, which we also see during the migrations, often in mixed flocks with Trumpeters. The Mute swan, which was introduced from Europe, has a large orange bill with a bump or ‘bill knob’ at the base of the bill. The Mute swan is a very large bird but it is still a little smaller than the native Trumpeter. Mute swans have been seen on the Kankakee river with cygnets in the springtime over the years, while Trumpeters east of the Mississippi nest on the wetlands in Wisconsin, Minnesota, Michigan, and southern Canada, and Tundra swans nest up in the Arctic. The loss of habitat and over hunting of the Trumpeters had a devastating impact on the swans, by the 1930s there were only 69 known to be alive in the United States. Biologists began an effort in the late 30s to save and expand the small population to other safe wetlands. There was a small flock discovered in Alberta Canada, and after Alaska became a state there were over 2000 discovered there. Today, according to the The Trumpeter Swan Society, the Interior Population is at 27,055, which is 40 percent of North America’s Trumpeter swan population.

Snowy Owl

Stretching before flying off to another perch, the Snowy owl shows its large yellow eyes just before spreading it’s wings.

December 24, 2020 – Perched at the top of a utility pole calmly scanning the surrounding landscape for prey, a beautiful Snowy owl appears in Iroquois County the day before our first snow. To the Inuit people of the north, the owl represents guidance and wisdom and has an important relationship with both humans and the environment. Snowy owl sightings have been reported in Northern Illinois and Northern Indiana recently as more birds move south to escape the blizzards and sub-temperatures of the Arctic. As I write this, there are blizzard warnings in the area of Iqaluit in the territory of Nunavut in Canada as a low pressure system is making its way through Hudson Bay toward southern Baffin Island bringing cold temperatures, snow, and 50 mile per hour winds. Here in northern Illinois the arriving Snowy owls are enjoying 37 degrees with 11 mile an hour winds on the mostly flat and sleeping winter landscape of the prairie state that somewhat resembles the Arctic tundra above the tree line, a place familiar to the owls. The female Snowy owl is larger than the male and has a wingspan of about 4.5 feet and weighs almost 5 pounds. They have a white face and large yellow eyes, a black bill surrounded by feathers, and they have acute hearing and vision. These Arctic owls are the heaviest owls in North America. To observe them flying low over corn stubble here in Illinois, with their large white wings slowly flapping as they make their approach and glide towards a low perch with some cover hundreds of yards away is an amazing sight. The Snowy owls that have come south for the winter will start moving northward toward their breeding grounds in the Arctic in February and March, and most will be gone by April. The owls will be back on their snow covered breeding grounds where the courtship will start in early May. The cycle will continue high in the north as new generations will be fed, protected, and fledged, and maybe even spend the cold months in a field near you, here in Illinois.

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.

Sandhill Cranes

Walking together at the edge of a grassy field some adult and juvenile Sandhill cranes move to join a larger flock at the edge of a wooded area.

November 12, 2020 – It’s that time of year when those amazing bugling and rattling sounds from thousands of Sandhill cranes echo across the countryside of Northern Indiana at the Jasper-Pulaski Fish and Wildlife Area just north of Medaryville, a little over an hour east of Kankakee. Jasper-Pulaski FWA is a great place to witness the fall migration of the Sandhill cranes where they can easily and safely be viewed from the parking lot at the Goose Pasture viewing area or from the nearby viewing platform. As more cranes arrive and numbers continue to grow, so do visitors who want to experience that autumnal spectacle of nature that can quite easily overwhelm the senses with the sights and sounds that have occurred each fall across the great Midwestern prairies for thousands of years. Mid-November is considered the peak time for highest numbers of cranes, with a record number topping 30,000. By mid-December, many will have moved further south, but it’s no secret that there is a healthy winter population of cranes that remain in the general area. Even during the harshest of winters, cranes can be found in the bean and corn stubble foraging. Currently during the fall after leaving the roosting areas for the day, the cranes can be found feeding, socializing, and resting in the harvested agricultural fields and on the grassy areas along the big drainage ditches. Sunrise and sunset are great times to experience large flocks leaving the roosting marshes in the morning and gathering at the Goose Pasture, or again after a day of feeding in the agricultural fields, returning about an hour before sunset in large numbers. There is nothing more surreal than viewing Sandhill cranes in large numbers as far as the eye can see, stretching out across a rolling landscape and looking more like herds of ice-age animals than flocks of birds. It is truly an amazing sight.

Lying down in the soft grass on a sunny morning some Sandhill cranes look to be enjoying the mild November weather.

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 Swamp sparrow

October 15, 2020 – The Swamp sparrow is an elegant, long-legged, medium-sized sparrow that is well adapted and right at home in the thick cover of marshes, swamps, and bogs of the north across eastern and central North America, stretching up into Canada’s Northwest Territories during the nesting season. The Swamp sparrow is more often detected by its song rather than actually being seen in its’ dense summer habitat of sedges, cattails, and shrubs. The variations of songs and calls of the Swamp sparrow have been studied, admired, and described as a slow, sweet, trill that will evoke the vision of a northern wetland to the observer just as the call of the Common loon sends ones’ thoughts to a clear secluded lake in the north woods. Ornithologists have even discovered regional dialects for Swamp sparrows located in different parts of the country. Through the study of the Swamp sparrow’s songs and calls researchers have gained an understanding on how these birds learn and continue to use songs that vary across different geographical regions, and how the sparrows are influenced as young by the popular songs used by the adults of those regions. It seems the most popular songs are the ones that are learned and repeated by the new generation of sparrows and any new variation that a young bird may come up with in its’ song learning practice that is not useful will soon fade away over time. The study also shows those popular songs have persisted in those regions for generations, possibly hundreds of years. The term used to explain how these song types are learned and stay popular to a region is known as “conformist bias”. The sparrows have a song repertoire, depending on the region, of popular tunes that have stood the test of time over many generations, influenced by the adults and put in to practice each year by a new generation of Swamp sparrows. Those tunes that work ring-out across the varied wetlands of North America.

Wonderful colors of reddish brown, blacks, and gray plumage adorn the long-legged Swamp sparrow as it pauses for a moment in its search for insects.

Crowns of Gold

An adult Golden-crowned kinglet pauses for only seconds on a handy perch before flying down into a thick weedy patch to search for insects.

October 8, 2020 – A small flock of Golden-crowned kinglets that had moved south out of their northern breeding range of Canada and the upper Great Lakes were busy foraging for insects south of Kankakee this past week. A cold front brought the chilly winds of change out of the north that provided incentive and opportunity to move south and many birds, including the kinglets, took advantage of the prevailing winds to do just that. Holding quite still, being very careful to resist sudden movements that might frighten the petite, swift moving birds, I was able to easily observe the kinglets as they went from dried weed stems, to low hanging branches, and back again searching for insects. Sometimes the little hunters were only a few feet away, too close for a long lens, but just right for a memorable experience. This encounter was some good medicine, the kind of medicine that can easily provide a temporary reprieve from the tightly wound human existence for any willing person that would take a moment to pause and look around. Larger than the hummingbird, the Golden-crowned kinglet is one of North America’s smallest birds. They have a black and white striped face, olive colored back with wings that have two white bars, and their round little bodies are white and pale gray on the underparts. The kinglets have black legs and yellowish feet that look as though they are wearing little golden socks. Both the male and the female have the bright yellow stripe on their heads, that golden crown from which they get their name. The bold yellow stripe almost seems to flash like a tiny beacon as they move through the shadowy patches of undergrowth at the woods edge. The male birds show some orange color blended into their golden crown that becomes more noticeable when their flashy crest is raised. As the little birds move south on their short-distance migration they can turn up almost anywhere, even near backyard feeders where other birds are foraging. Some will continue south while others will spend the winter in our area, preferring stands of conifers that most likely provide some protection from the bitter cold and a safe retreat from predators.

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.
