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.
May 7, 2020 – A large number of shorebirds stopping off in Iroquois County on their spring migration could be seen feeding in a flooded field this past week. There were at least twenty Lesser Yellowlegs, and four Greater Yellowlegs, along with some Short-billed Dowitchers, and some small Dunlins. The variety of shorebirds were working the shallow waters and shoreline searching and probing in the soft mud for worms, arthropods, and other tiny creatures to replenish their fat reserves and building up the needed energy to reach their summer nesting grounds for the breeding season. Even more exciting were some obviously larger and less often seen visitors that seemed to dwarf the other species. There were four large shorebirds that are called Willets, all in their breeding plumage. The Willets are slightly larger than the more common Greater Yellowlegs, which is also a fairly large shorebird and is often seen in our area during the spring and fall migrations. The Willet has a heavier build than the Greater Yellowlegs, a thick straight bill and long legs for wading. Willets are seen during the winter months along the seacoasts of North America, Mexico, Central America, and South America. They nest inland making their nests in small depressions lined with grasses on the prairies of Northwestern United States and into the grasslands of Southern Canada. Some eastern Willets nest closer to the coast in the salt marshes and dunes of the Northeastern United States as far north as Newfoundland. Even more rare to see here in Northeastern Illinois was a very large shorebird with a long multicolored upturned bill. This large heavy looking bird, known as Marbled Godwit, is a little bigger than the Blue-winged teal ducks that were swimming nearby. The Marbled Godwit has a winter range on coastal beaches and mudflats almost identical to the Willet winter range. The Godwits nest in the native prairie grasslands, preferably close to wetlands located in the northern boarder states of the great plains and on into southern Canada. The Marbled Godwit is a very large sandpiper that has an interesting color and shape to its’ extra long bill. The bill is sword shaped, slightly upturned, with a dull pinkish to bright orange color extending from the base that continues about halfway down the bill where it turns dark all the way to the tip. These temporary flooded areas that were once wetlands across the prairies and are dreaded by today’s farmers are always a challenge to agriculture but they do play an important role with migratory shorebirds as they travel hundreds to thousands of miles in some cases to their summer and winter ranges.
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 16, 2020 – When the spring rains create temporary flooded pools in the agricultural fields, pastures, and on the low well saturated land of restored prairies here in Northern Illinois, the migratory shorebirds large and small will show-up tired and hungry. A variety of shorebird species are working their way across Illinois this time of year. These birds must feed and rest and sometimes wait for the right weather conditions as they instinctively know when to continue the push north. The mudflat-like edges surrounding the flooded slow draining areas in the fields are the perfect habitat where these birds can find the tiny worms, mollusks, and insects that are important to rebuild their depleted energy. Building up fat reserves and resting is key to the survival for both medium and long distance migrants as they pass through on their challenging springtime journey, moving to their northern summer nesting areas. Many of the shorebirds travel great distances to reach their nesting areas on the high Arctic tundra. Pectoral Sandpipers spend the winter on the wetlands and agricultural areas of South America but they nest many thousands of miles north on the sometimes cold springtime Arctic tundra. Here in Illinois we see many flocks, some quite large, of the Pectoral sandpipers using the flooded fields to rest and feed as they work their way north. The sandpipers stay together in and around the flooded wet spots feeding, preening and occasionally taking to the air when a bird of prey comes too close. Flying in a tight pattern the birds circle back and forth until all is clear and then quickly return to the same wet spot to continue their feeding. The much larger Greater Yellowlegs has longer legs than the Pectoral Sandpiper and are often in deeper water searching for prey. The Greater Yellowlegs migrates a shorter distance than the Pectoral. They spend the winter on the Atlantic coast, the Gulf coast, Florida, Mexico, Central and South America. The Greater Yellowlegs nest across Canada just south of Arctic Circle and on the coastal areas of Southwestern Alaska. Those are just two species that are fairly easy to identify during the northern movement, there are many others to watch for in these short-lived shallow pools that temporarily linger in the fields. Some of these shorebirds are quite small, others are in their impressive breeding plumage, sometimes there are rare species, but one thing is for sure they all are in need of food and rest as they still have many miles ahead.
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.
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.
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.
