January 10, 2022 – The bleakness of a winters afternoon and the silhouette of a small songbird off in the distance perched at the end of a spindly sapling can send chills having nothing to do with the cold weather down the back of even the strongest and most rational when the sweet songs barely heard are that of the butcherbird. An uncommon winter visitor, the Northern Shrike is about the size of the American Robin, with similar colors to that of the Northern mockingbird. Northeastern Illinois and northwestern Indiana are on the southern edge of the Shrikes winter range, where a lucky few get to see this remarkable bird each year. The shrike prefers open wetlands and shrubby grassland areas with tall saplings and snags to perch on to watch for prey. The little songbird is much different than the other songbirds that live or spend the cold winter months here in northeastern Illinois. The shrike has an appetite for small rodents and other birds; it is a swift, effective hunter with a sharply hooked bill and a tomial tooth, a tooth-like feature on the upper part of the beak similar to falcons and is used to dispatch their prey. Northern Shrike is also known as the butcherbird or the butcher watchman, names well earned from its’ macabre survival skills. Birds of prey like Hawks, eagles, and falcons have powerful talons that are key to securing the victim. The Northern shrike has claws that are not any different than other songbirds. To help hold their victim while tearing into the flesh with their strong-curved bill, the shrike will carefully impale the prey on the pointed barbs of a barbed-wire fence or a long thorn. A fork in a convenient tree also works well to secure the victim. Killing more than it can eat caching of prey is a survival skill and can grow to six or seven locations throughout the shrike’s wintering territory. The Northern shrikes breed in the partly-open areas of the far north along the Arctic circle from Alaska east across northern Canada and south around Hudson Bay to Labrador.
August 9, 2021 – Gone but not forgotten, the rare visitor at the Willow Slough Fish and Wildlife Area in Newton County, Indiana, a little over 30 miles southeast of Kankakee, was witnessed, documented, and photographed by many lucky observers. The raptor was in the area of the Willow Slough shooting range for over two weeks in August. It spent much of its morning hunting near the shooting range. The impressive bird of prey has a four-foot wingspan and long forked tail. The bird would circle above the prairies, soaring and gliding near the shooting range; it would dive down to catch dragonflies and cicadas that it would eat on the wing before continuing its hunt. The kite is a master of flight and was exciting to watch with its beautiful white head and body, black on its back, tail feathers, and wingtips.
September 9, 2021 – Some strange sounds were coming from the cattails as I approached the edge of the slough, a startling communication among the shadow skulkers that slowly and eerily waned with each note. The distinct, loud, and familiar alarm calls from a well-hidden creature instantly conjured the vision of a small marshland bird common to this area during the warm months. The Sora is a water bird about the size of a robin, Soras nest in our area of Illinois from May through August. They build a woven platform nest out of grasses and cattails above the waterline, creating a kind of hollowed nest that adds protection from predators and the elements for about a dozen eggs. After some quiet and patient waiting time, on my part, some movement caught my eye among the shadowy cattail stalks just to my left. A juvenile Sora appeared and was foraging much like domestic fowl, plucking the ground as it cautiously moved in an unpredictable jerky and bobbing motion. The bird probed with its thick yellow bill into the soft, damp, ground watching and feeling for prey as it braved into the clearing. The flashy white stubby tail of the small bird would stand straight up at times as it stretched its neck to pluck a small worm or a tiny insect from the muddy earth. Soon three more Sora appeared; two adults and another juvenile wandered into the broken light and began their search for insects, seeds, tiny worms, and mollusks. As one of the juveniles worked its way across the open area, an adult squawked with a rapid, high-pitched call while running swiftly towards the juvenile bird, chasing the young bird around almost in circles until the intruder retreated into the cover of the cattails. Less than five minutes later, the scolded young Sora returned quietly out of sight of the adult to resume foraging. The small rails remind me of a miniature chicken, a bird that would not seem to be a strong flier. It is amazing that the Soras travel many hundreds of miles to their winter range along the coasts of the Gulf of Mexico and the marshes of Central America each fall and then return to the Midwest to nest in the spring.
July 8, 2021 – Wetlands, creeks, lakes, and rivers across Illinois provide a good summer habitat during the nesting season for the Green heron. These small herons, also known as little Green herons, are often seen perched in the trees around wetlands or silently hunting in the shallows for fish, frogs, and even small snakes. The keen eye of the skilled observer can find these well camouflaged little birds standing at the waters edge almost motionless while hunting. The Green heron, that are about the size of a crow, are often seen searching for prey along the shadowy, damp banks of a meandering creek, or hunting the still dark waters from a low branch just above a fishy habitat. They are common to lakes, ponds, and wetland habitat where their prey is available. Appearing dark in color from a distance, the Green herons are often crouched down and standing as still as a statue, any movement from the little bird is slow and precise as they intently focus on the task of watching for the slightest ripple or movement from an unsuspecting prey. It is well known and documented that Green herons are part of a small group of birds that at times use bait to attract prey. The cunning birds drop insects, small sticks, or tiny feathers on top of the water to lure fish close enough to catch them with their long dagger-like bill. Getting a good close look in the bright sunlight, the adult Green heron reveals their long bill, short bright-yellow legs, and the rich colors of a plumage that is gray, blue, chestnut, and of course, the subtle greens on the back and wings. Late winter through early spring the Green herons work their way north out of Florida and areas of the Gulf Coast for the nesting season. The herons nest from May through July where they have two to five eggs in a nest that is built on a platform of sticks. Both parents incubate the eggs and feed the young nestlings caring for the birds for a time even after they leave the nest. By late August the adults and a new generation of Green herons are making their way to the warm winter habitat of the far southern states and coastal areas of the Gulf of Mexico and beyond.
March 11, 2021 – The rapid warming of our planet’s surface temperature has caused a wobbling of the jet stream over the Arctic that allowed for some very cold Arctic air to escape and move south across the United States in February bringing plenty of snow, ice, and a challenging late winter for the lower 48. The impact of the extended cold and snowy conditions on wildlife couldn’t have been more apparent as it was in Texas during the Polar Vortex event of 2021. Thousands of sea turtles in the Gulf of Mexico that were stunned from the unusual cold conditions had to be rescued and cared for during the extended winter storm. Many bats were found dead or injured under bridges due to the extreme cold temperatures. Much of the wildlife has had some kind of negative impact in those areas of Texas that is not used to those extended cold temperatures. From plant life, to fish, and migratory birds, those kinds of extreme cold conditions were a challenge and even a death sentence for many, the effects from this event are still being assessed in that region. Here in Northern Illinois now that we have moved into March, the blanket of heavy snow has retreated and the iced-over waters of lakes, rivers, and wetlands have become ice free as the arctic temperatures seem to be behind us now as the jet stream has regained its strength. A few weeks ago at the end of February, as weather conditions began to show a slight improvement each day with some warming sunshine, a slow melting of the snow was going on revealing tiny bits of last falls’ dropped beans and corn. Turkey, deer, quail, and pheasants were congregating in these small open spots scratching the snow, searching for food after the long spell of deep icy snow-cover. Long periods of cold and snow becomes hard for wildlife if food remains buried and frozen under the snow for long periods. When the wildlife have only their fat reserves to rely on because they can’t get to the food, that is when things can get dangerous if the weather doesn’t improve. Here we are nearing early spring, only remnants of snow remain. Many species of waterfowl are moving through the area, some are here to nest while others are waiting for just the right time to continue north. Food is a little easier to find now and the migration will ramp up over the next few months as the cycle continues as warm weather prevails.
January 21, 2021 – A little bit smaller than the Merlin falcon and very close in size to the Mourning dove, the American Kestrel is the smallest falcon in North America. These determined little predators are focused hunters, whether perched on a utility wire, fence post, or hovering over grassy areas intently watching for any movement from small mammals, insects, and birds. Their keen vision and superb flying ability allow for a stealthy and swift attack from above on their unsuspecting prey. The drama of predator and prey plays out hour after hour, day after day above the grassy areas along the rural roads, ditches, and busy highway medians here in Northeastern Illinois and across the United States. Because of their small size the falcons go mostly unnoticed by humans speeding past the little perched hunters. It doesn’t take much effort to be just a bit more observant to a moment in nature, it will quickly become almost impossible to not see these little predators perched and hunting. Soon the sightings of Kestrels add up and the mind expands beyond the mundane for the human observer as that moment in nature is understood. Also known as the Sparrow hawk, the Kestrel is certainly the best known and most colorful and boldly marked falcon in North America. The male Kestrel has slate blue-gray colored wings while the females have reddish-brown wings,a heavily streaked chest and they are also up to 15% larger than the male. The bold and vibrant colors of the male Kestrel are quite intense under bright sunlight. The females, while they still have beautiful colors, are less vibrant than the males. The Kestrel lives year around in Illinois and nest in natural occurring places like rock crevices and overhangs, they also take advantage of abandoned woodpecker holes, man-made nest-boxes, old buildings and structures near a good hunting area. They most often have only a single brood. Incubation of four or five eggs last about 30 days, the female will brood for about nine days after the last egg has hatched and then only at night or during harsh weather conditions. The American Kestrel falcons are widespread in the Western Hemisphere and occur from Alaska and Canada to Tierra del Fuego in South America.
January 7, 2021 – Each winter Bald eagles move south into Illinois in large numbers as hundreds can be seen perched in the tall Sycamores and Cottonwoods along the Mississippi river, near the locks and dams, where the churning ice free waters are abundant with fish that are easy pickings for the eagles. From December through March these wintering eagles are not hard to find, where there is fish there are eagles. There are festivals and eagle watches at many cities and parks that have rivers and lakes throughout the state. These celebrations give people the opportunity to learn about eagles from experts while observing these great birds of prey in the wild. Some of the eagle watching events may understandably be postponed or canceled this year due to the coronavirus but eagles can still be observed from the safety of your vehicle from the parking areas around lakes and along rivers. Recent estimates of wintering eagles in Illinois is over 3000 birds. The U.S. Fish &Wildlife Service estimates in 2004 there were 100 nesting pairs in Illinois, a number that has likely increased. The American Bald eagle is becoming more of a common sight here in Illinois in recent years. The Bald eagle recovery is the absolute result of the hard work of dedicated biologists, environmentalists, and citizen scientists. A number of state and federal laws enacted over the years, beginning with federal protection specifically for the eagle, was passed by Congress in 1940. Shortly after the Bald Eagle Protection Act became law the Golden eagle was added, and the name was changed to the Bald and Golden Eagle Protection Act. In 1972 the synthetic pesticides DDT that was being widely used and released into the environment without the proper understanding of the long and short term affects on humans and wildlife was banned in the United States. Rachel Carson’s celebrated but controversial book published in 1962, Silent Spring, raised public awareness with an urgent message of the danger and damage being done to the environment with the use of the pesticide DDT. It was found that DDT does not break down easily and builds up in the tissues of animals causing problems up the food chain. DDT was believed to have a profound consequence on Bald eagle reproduction causing their eggs to be brittle and easily damaged while being incubated. Eagle populations began to drop dramatically until the ban on DDT. Today eagles can be seen year around on the Kankakee and Iroquois rivers and with a little patience and some binoculars you are likely to be rewarded with something memorable.
December 31, 2020 – The colors of the summer prairie are all but forgotten as the chill of December takes hold across a landscape of golds, browns, and faded tans. Snow squalls move across the land with the bitter winds, reducing visibility and dimming down the sunlight reminding us that it is the end of December and winter holds the cards. The subdued sunlight does appear at times, filtered but shining through the gray and white ever- changing troubled and cheerless clouds that seems to roll like a swollen river, fast and turbulent across the bleak wintry sky. Wildlife behavior has changed with the cold weather as great flocks of Sandhill cranes in Northern Indiana huddle together like blizzard bound Emperor penguins of Antarctica as the temperatures drop by 40 degrees. Birds of prey feel the sting of winter but must continue their hunt no matter what the weather conditions are. Red-tailed hawks, Kestrel, and Merlin falcons watch the ground below a convenient perch on a blustery day ready to quickly pounce on an unsuspecting prey like a vole or a field mouse oblivious to the danger above. Rough-legged hawks expend precious energy hovering and fighting the challenging winds while Northern harriers fly low into the gusts gliding from side-to-side over the winter grasses along the perimeters of ditches and fields watching for signs of prey. The Short-eared owls are hunkered down in the shelter of the prairie grasses and the thick cover along the drainage ditches and fence-rows until late afternoon when the sun nears the southwestern horizon. On this day though, with the strong and relentless winds, the medium-sized owls may wait for conditions to improve before taking to the sky for the hunt. The Short-eared owls are wintering on our restored prairies and CRP grasslands of Northeastern Illinois and Northwestern Indiana and are considered a medium-distance migrant that will leave their wintering sites by March. There was a time in Illinois when Short-eared owls were common throughout the state but they are now an endangered native. Wetlands and grasslands destruction is the main reason for their decline. Restoration of large areas of grasslands and wetlands would provide a safe place to winter and could also provide a safe place to nest someday.
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.
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.
