July 2, 2020 – Several acres of low ground in Iroquois County that is surrounded by a large tract of lovely cultivated prairie has retained water for a number of months providing a perfect habitat and a food source for resting ducks, geese, herons, egrets, and a number of species of migrating shorebirds. Now, as the water is disappearing and the temporary wetland pond is starting to dry up, it is resembling a coastal mud flat, with small areas of water that are barely a few inches in depth. The small pools of water now hold concentrations of crayfish, frogs, and turtles, and the muddy areas expose worms, snails, and insects for an easy meal for the visiting wildlife. The puddles and the surrounding mud left behind, that was until recently covered in at least a foot of water, has attracted gulls, grackles, and even a family of raccoons that are visiting the buffet daily feasting on crayfish. Individual grackles that are part of several large flocks can be seen at times standing over a crayfish that is in a defensive posture with its’ pincers up towards the much larger bird. The grackle will try repeatedly pecking at the crayfish but if the crayfish is too large and aggressive the grackle will move on to an easier prey. A lone Bonaparte’s gull wades through the shallow, dirty, water stirring it with its’ feet as it searches for snails, worms, or any other likely prey in the dwindling pools. A pair of rare King rails staying close to the tall grasses and aquatic plants wander out into the open areas searching for the abundant crayfish. The skittish rails cautiously hunt the edges of the little pools for prey and even at some distance away, when the prey is spotted, the rail quickly dashes over and grabs the little crustacean and hurries back closer to the safety of weedy cover. The King rail, the largest rail in North America, begins removing the pincers from the crayfish before eating it by grasping the large claws and shaking the crayfish violently until those large intimidating claws are removed. The King rails are not as common in Illinois as they once were because of the loss of wetland habitat, the Illinois Natural History Survey explains their occurrence in Illinois as uncommon migrant and locally uncommon summer resident.
May 28, 2020 – Standing out among the greens and yellows of a spring prairie that surrounds a shallow, seasonal, wetland of only a few acres, the bright white color of the four migrating Cattle Egrets in Iroquois County recently made for an easy count. While two of the birds were occupied preening, the other two were busy hunting through the prairie flowers and grasses for prey. Earthworms, frogs, and insects were on the menu this day. The egrets eventually came into range as they worked their way around the waters edge hunting the surrounding grasses. I could now observe through my camera their successful hunting techniques getting a close-up look at their focused behavior as they cautiously stepped through the taller grasses carefully looking for prey. A large nightcrawler worm is consumed quickly, but a big frog takes some work to dispatch and eat, a process that quickly becomes a challenge to keep the catch from being stolen by another egret. Before long, keeping the frog turns into an aerial pursuit across the water to the other side of the wetland where the successful hunter eventually wins the prize as the thief soon gives up.
Cattle Egrets are not native to the Americas, they are believed to have flown across the Atlantic via the northeast trade winds and arrived in South America in the late 1800’s from Africa. The Cattle Egrets expanded north into North America and were nesting here by the 1950’s. Most people would recognize images of these birds in the country from which they migrated from, Africa. One can easily visualize these birds perched on a large Cape buffalo, Zebras, or walking around close to the trunks of grazing Elephants. Here in America the egrets are often seen in cow pastures perched on domestic livestock and walking near the head of foraging cattle waiting for insects or other prey to be flushed by the large grazer. The little birds have no problem plucking insects and parasites off the faces of the cooperative cattle. These recent visitors to Iroquois County were in their beautiful breeding plumage. Three Cattle Egrets in breeding plumage were most recently reported by Jed Hertz in Kankakee County feeding in a similar habit as those found in Iroquois County.
May 21, 2020 – As we near the end of May we are about two thirds of the way through another spring season as newly arriving migratory birds continue to be seen in our area of Northeastern Illinois as summer draws near. The Great Crested Flycatcher is a recent arrival and is a large colorful bird that has a bright yellow belly and an impressive crest on top of its’ head, that feathery crest promptly raised straight up when the bird is excited. These beautiful flycatchers can be found hunting along wooded areas and near grasslands and along the rural roadways of Illinois. Sightings of this common bird are now being recorded in Northern Illinois and one was just recently found in Iroquois County hunting the edge of a small woods perched near some tall grass. The Crested Flycatcher stands out among the smaller and more drab flycatchers like the Eastern Phoebe and Eastern Wood-Pewee that have the same hunting behavior and can be found hunting the same territory. The Great-Crested Flycatcher winters from southern Mexico south into South America. Another recent arrival that looks quite dignified covered in black and charcoal-gray feathers, white throat, chest and belly with white-tipped tail feathers is the Eastern Kingbird. Like other flycatchers the Kingbird prefers perches near open grassy areas with a good view of flying insects where the fast flying, quick turning, Kingbird will quickly catch the prey on the wing. The Kingbird spends the winter in the western Amazon basin of South America and nests in almost all of the United States, except for the deep southwest. It also nests in most of southern Canada from the Atlantic to the Pacific. Exciting flashy red male tanagers, both Summer Tanagers and Scarlet Tanagers, have just recently arrived. The female Scarlet Tanagers do not have those bright red feathers but are covered in olive-yellow plumage with dark wings. The Summer Tanager females are mostly yellow and do not have dark wings. The Summer Tanagers are a long-distance migrant that winter in southern Mexico, Central America, and northwestern South America. The beautifully striking Scarlet Tanager spends the winter months in the foothills of the Andes in South America. This year seems to be a banner year for Scarlet Tanager sightings as there are a large number of people reporting and photographing for the first time Scarlet Tanagers at their backyard feeders Ruby-throated hummingbirds are establishing territories near good food sources and a variety of colorful warblers continue to excite birdwatchers as many will be nesting here and others will continue north.
May 14, 2020 – The Black-necked Stilt is an elegant wader with some extremely long pink legs and a body covered in black over white plumage, it has a long neck and a small head with a long thin black-colored needle-like bill. This is a lovely, delicate, and regal looking shorebird that proportionate to its’ body, accordingly to the American Bird Conservancy, has the longest legs, second only to the flamingo. Standing out, a migrating pair of Black-necked Stilts were busy feeding in a flooded field this past week in Iroquois County. At one point while observing the pair, the birds came together in a display of their courtship ritual and breeding behavior that is initiated by the female. Standing close together, the male began with a bit of preening as well as the female, then together they began to stir the water rapidly with their long bills. The female stood with her head extended and her back flat, an invitation for the male who promptly climbed on the females back. He slowly folded his long legs and settled down, but moments later, less than fifteen seconds, he was back in the water where they stood snug together. The stilts then put their heads close together and the male put his bill over the top of hers with his wings partially extended as they stood still in a moment of intimate display, an affirmation to their commitment. The breeding was complete. Black-necked Stilts winter along the southern coastlines and south into Central and South America. These birds are known for nesting in numbers in the western United States, but nesting records have been showing up in Midwest in recent years. Observations by Jed Hertz of Kankakee have shown adults and then eventually juvenile Black-necked Stilts together in suitable nesting habitat during the nesting season in Kankakee County. There was also a nesting attempt at the LaSalle Fish & Wildlife Area along the Kankakee River in Newton County Indiana a few years ago.
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.
April 9, 2020 – As nature steadily advances into another spring, more species of birds appear in the thicket each day. Some don’t stay long and leave during the night, while others spend a few days or even longer resting and feeding on the abundances of emerging insects and the remnants of last years seeds. A few Golden-crowned Kinglets are noticed high-up in the tree canopy searching every limb and branch for insects. On the perimeters of the small woodlot, any tall dried sturdy stem, or low hanging branches near the weedy ditch, becomes the ideal perch for some Eastern Phoebes that are busy catching and consuming small insects on the wing. The elegant little flycatchers quickly return to a nearby branch to continue their hunt after successfully spotting, pursuing, and catching an insect. A pair of large Northern flickers are only sometimes visible as they search through the tall grass chiseling into the earth with their large powerful bills looking for ants and other insects. Movement on the ground near some thick cover alerts me to not one, not two, but three Hermit thrushes searching in a stop and go method for insects in the dark shadowy places among the leaf litter and new growth on the forest floor. A tiny Winter wren, our smallest wren, searches the decaying remains of a fallen tree for insects. The small brown wren is hard to see as it disappears into the dark nooks and behind the twisted dead limbs of a once mighty tree. Soon the little bird reappears, only for a moment, as it continues to looks for a meal but quickly vanishes once more. Building strength before continuing north on their spring migration gives the travelers, both long-distance and short-distance migrants, the best chances for another, or even a first time, successful nesting season. The countryside is greening up, grasses are quickly growing, many trees and shrubs are just beyond buds with tiny, furrowed, developing leaves. The sound of chorus frogs ringing out from every ditch and wetland puddle across Illinois is signaling those glorious vernal changes that seem to appear overnight revealing a new beginning.
January 9, 2020 – Here in Northeastern Illinois it has been a warmer, more forgiving winter leading up to the new year, and the relatively mild conditions that we have been enjoying have also continued into early January. Open water, and mostly snow-free fields means that there is easy foraging for both migratory and resident wildlife such as birds, waterfowl, turkey, and deer. Large flocks of wild turkeys can be seen feeding on plant material and the spilled grains from the last harvest in the snow-free agricultural fields, the cautious birds usually not far from the safety of their wooded escape. Much like White-tailed deer, wild turkeys separate into groups depending on the time of year. Young male turkeys, in late fall, form jake flocks after leaving their brood flock. The hens also group up after brooding their young. The adult male turkeys stay in bachelor groups until the breeding season arrives in the spring. March and April is the time that the male and female turkeys are joined together in large flocks and then eventually into smaller breeding flocks that are made up of a few toms with ten or fifteen hens. White-tailed deer also form bachelor groups. The bucks group together throughout the spring and summer months and unlike the turkey bachelors that are made up of mostly adult birds, the deer bachelors are made up of many different ages of males. During the warm summer months the White-tailed bucks are growing their antlers back after losing or shedding them during the winter and after the rut (active breeding time). The new growth of antlers starts in the spring and noticeably start out as velvety nubs. During the time of the bucks antler regrowth, the females or does, are giving birth during the spring and summer. By fall the antlers of the White-tailed buck are fully developed. Some antlers are small and are called spikes. While most are average in size there are a few that are huge and impressive but rarely seen. The White-tailed deer in late fall begin another breeding season. The bachelor groups break up and the bucks go their own way in search of does. The wild turkeys, the toms, the hens, and the jakes are still in their groups waiting for spring and another nesting season.
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.
December 12, 2019 – Four fine-looking multicolored male Ring-necked pheasants cautiously search the ground for seeds and insects, pecking with their pale-yellow curved beaks at the low grasses and dried leaves, along the edge of thick cover, this past week in Iroquois county. The elaborate flashy birds could be heard vocalizing, much like farmyard fowl, as they nervously moved away from the photographer. The male pheasants, commonly called roosters, have some spectacular colors with long, elegant tail feathers. The females or hens, however, have shorter tail feathers and are well camouflaged for nesting and caring for their brood. The Ring-necked pheasant was introduced to the United States in Oregon in 1882, after several attempts at releasing the exotic birds into the wilds of the northwest were needed. Eventually the transplants were successful and began to take hold. The introduction of the Ring-necked pheasants continued across the county. Over many years the pheasants have been a common sight and a popular upland game bird for hunters in and around the grassland and agricultural fields here in northern Illinois. The removal of hedge-rows along with the clearing of small stands of timber and brushy areas has taken away the needed habitat for the pheasants and native wildlife alike. The wholesale clearing of habitat has made the pheasants vulnerable. Sightings of pheasants have been less common in areas where the habitat has disappeared. The grasslands and brushy idle areas provide cover from predators and the sometimes harsh weather conditions here in the Midwest. Wet springs with flooding have a negative impact on nesting birds, likewise the exposure to heavy snows and sub temperatures can be hard on the birds when they can’t find cover for refuge. Fortunately for these celebrated game birds efforts by conservation groups, sportsman, and land owners working together to provide and restore habitat needed by the pheasants seems to be a successful and an ongoing desire that benefits native wildlife as well. An slight uptick in reported sightings recently here in northeastern Illinois seems to tell an encouraging story for the Ring-necked pheasant.
December 5, 2019 -Recently, on the 18th of November, the people of Barrow Alaska, at a latitude of 71º north, got their last glimpse of the Sun until late January 2020. Over these next few months, winters’ frigid grip will take hold in the extreme for the people and the wildlife above the arctic circle. Those high latitudes will become a dim world of unforgiving temperatures, short days, civil twilight, and darkness. One feathery inhabitant of the north is the Snowy owl, also known as the Snow owl, Arctic owl, and Ukpik in the Inukitut language of the Inuit people that live north of the tree line. Many of these beautiful white owls will move south off of their summer nesting range for the winter, but not all. According to Project Snow Storm, an ongoing research project into the yearly movements of Snowy owls, some of the owls actually move further north onto the Arctic sea ice to hunt through the winter. The second largest and heaviest owl in North America, the Snowy owl lives and breeds on the arctic tundra and spends the winter over a wide range from the interior and southern coastline of Alaska, across the Northwest Territories, most of Canada and south into the northern two-thirds of the United State including the flat agricultural land of Illinois. Some years, here in Illinois, higher numbers of Snowy owls are recorded, a phenomenon known as irruptions. Those record years of snowy invasions average every four or five years with the so called mega-irruptions bringing more owls further south then normal. I usually record a few Snowy owls in our area each year, but last year, 2017-18, I recorded seven and of course many other areas of Illinois saw an increase. Research has proven that an increase in prey animals like lemmings and voles on the breeding grounds of Snowy owls also insures the possibility of a successful nesting season. Irruption years of these white raptors spreading southward from their breeding range in the land of the midnight sun is always exciting and increases the chance encounter to actually witness this large white owl hunting over the croplands of Illinois.
