May 13, 2021 – As the springtime brings awe-inspiring color to the forest floor with a variety of wildflowers like Dutchman’s breeches, Virginia bluebells and Woodland phlox, likewise the flowering dogwood and redbud trees standout brightening up the understory with their new blooms that is easily visible through the emerging greens of the awakening landscape. April and May are exciting months here in Northeastern Illinois and as the new plant growth comes in, there are also migrating birds arriving and bringing their own variety of color and excitement. The bright orange plumage of the male Baltimore oriole is a highly anticipated favorite this time of year to the backyard feeders. These long-distance migrants are lured in with grape jelly and cut oranges that feeders put out, and these birds never disappoint with their rich songs and amazing beauty. Cat birds, King birds, and flycatchers have arrived to take up summer residence for the nesting season. A variety of small colorful warblers, drab kinglets, and tiny Ruby-throated hummingbirds appear like magic, some are here to nest while others are just passing through on their way much further north. Many species of well known birds show up like clockwork each year, their songs and their plumage are as familiar to most as the clouds in the sky. But there are other birds like American Golden-plover that go practically unnoticed even though they spend three or four weeks staging on the agricultural fields in our rural areas of Iroquois and Kankakee counties. The American Golden-plover is larger than a robin but smaller than a crow. It is not always easy to spot in the farm fields with its dark colored plumage, a good camouflage for a ground nesting bird like the plover. Even when there are hundreds of birds in a field they can be easily missed by the passerby. These birds have come a long way from their winter home on the grasslands of Argentina and Uruguay and it is an amazing sight to see them over the few weeks they spend here waiting for the right conditions to move north. When the plovers do finally leave for their nesting grounds they will fly above the Arctic circle onto the vast tundra from Baffin Island to Alaska completing the northbound part of their trip of over 8000 miles.
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.
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 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.
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.
February 20, 2020 – The big raspy voice of the little White-breasted nuthatch is a familiar sound in the winter woods of Illinois. Throughout the softly illuminated and leafless winter forest, or at a busy backyard feeder, it is easy to spot those colorful little hunters as they noisily swoop in. Suddenly there is a flash of blue-gray, then another, and yet another as four, maybe more of those regal looking little birds appear. A male and a female nuthatch light on the patchwork bark of a large sycamore and quickly begin searching tree and limb for food. The little birds move up and down the trunk like acrobats as they move head first down the tree searching the nooks and crannies for insects. Not long after the small winter flock of White-breasted nuthatches appear, their songs begin to fade into the distance as they continue their search for food on the trees and shrubs along an overgrown and abandoned road that the woods has mostly reclaimed. The White-breasted nuthatch is common across most of the United States and is a year-round resident here in Illinois. The male nuthatch has a dark black cap, white face and underparts with splashes of chestnut colors under the tail. Their wings and back are mostly blue-gray. The little birds have large heads, large feet, and a long pointy bill. The female looks pretty much like the male nuthatch except they have more of a gray colored cap with stronger chestnut coloring near their rear under the tail and their overall colors are a bit weaker than the male. The nuthatches eat nuts, acorns, insects and cache food items around their territory. You may find the winter flocks of nuthatches mixed with chickadees and woodpeckers.
June 27, 2019 – A closGrowing low to the ground and hidden in the spring vegetation on a well drained sandy ridge or a sunny rocky slope, the native Eastern prickly pear cactus, also known as Devil’s-tongue, finally reveals its’ location when those magnificent yellow blooms appear. The Prickly pear can bloom over a few weeks in the late spring through early summer, but each one of those beautiful yellow flowers last but only one day. The blooms, which are great for the pollinators, will soon be replaced by the vitamin rich edible pear shaped fruit from which the cactus gets its’ name. e look at the flower of a Prickly pear cactus showing pollen covering the inside of the bloom.
The fruit, seeds, pads, and spines of the Prickly pear cactus have been used by the indigenous people throughout the ages. The early explorers sometimes found a challenging and painful travel, where there was an abundance of the Prickly pear, as they forged new trails. Wildlife, such as land turtles, ground squirrels and even deer are known to eat the pads and fruit of the prickly pear. Conditions are right for the Prickly pear cactus here in the Midwest where there is still undisturbed habitat on the sandy prairies, sandy savannas, and the sunny well drained open and rocky hillsides.
The Eastern prickly pear is the more common prickly pear found in Illinois but there is also the Brittle prickly pear cactus which is found in the far northwestern county of Jo Daviess and is considered endangered in Illinois. There is also the Big-rooted prickly pear that is also found in Illinois and looks very similar to the eastern prickly pear. The Eastern prickly pear grows from New Mexico, north to Montana and east to the Atlantic and south into Florida according to USDA NRCS National Plant Database. The cactus also is found in far southern Ontario which is at the northern edge of its’ range but is reported endangered by the Canadian Wildlife Federation.
June 20, 2019 – A female Dickcissel with her beak full of nesting material momentarily perches on a plant stem just before dropping down into the thick prairie grasses to continue the work on her ground nest. The ground nest is a large cup consisting of weeds and grasses with the softer material on the interior that will hold the brood. The nest will hold three to six tiny light blue eggs that will hatch in about thirteen days.
Nearby, the male aggressively guards his claimed territory, keeping intruders out that dare to venture too close. The female does all the work of building the nest and caring for the young. It seems that the male Dickcissel’s only job is to guard the chosen nesting territory. The male may breed with other females that are attracted to his perfect nesting habitat after the first female is on the nest according to The Cornell Lab of Ornithology. The Dickcissels arrive here in northern Illinois towards the end of May.
The male Dickcissels claim a territory where they sing practically non-stop from their perch on a tall prairie plant or the limb of a short shrub as they try to entice the females. The persistent songs of these sparrow sized grassland birds are common across the springtime prairies and rural agricultural areas of Illinois. The familiar sounds that echo from this little bird can easily identify the vocalist by this mnemonic pattern of “dick,dick,sizzle,sizzle”.
By November the Dickcissels have gone south to a more hospitable climate where food, grasslands, and farmlands are available during our winter months. The birds will winter in large flocks in southern Mexico, Central America, and Northern South America. If you miss them this year just remember next year near the end of May is a great time to listen for their songs when they have returned to the springtime grasslands and prairies of Illinois.
June 13, 2019 – The color indigo is described as a deep rich blue, and that is exactly what catches one’s eye at the forest’s edge beginning in the spring and lasting through the warm months of summer here in Northern Illinois. The flash of that stunning blue feathered breeder fluttering across a brown, black, and green environment can mean only one thing, that those long-distance migrants, the male Indigo buntings, in their alternate plumage, are here for the nesting season. The breeding range of the Indigo bunting stretches from central Texas north across the Great Plains into Canada, east to the Atlantic, and south into central Florida. The Indigo bunting winters in the southern half of Florida, the Bahamas, Cuba, southern Mexico, Central America and south into northern South America.
The females and immature Indigo buntings show less impressive colors than the breeding males. The females and immature birds are brown and tan, with some black in the wings, and dark broken streaks on a white and faded tan chest extending down the front of the bird. The female shows only hints of that famous blue on their shoulders and tail feathers. These little birds come a long way, about 1200 miles each way, in their amazing migration just to nest here in our area where there is suitable habitat of thickets and brushy wooded space bordering open fields and prairies. While many other migrating birds follow river valleys and other landmarks by day, the Indigo bunting uses the celestial map above for navigation making their magical journey on those clear dark starry nights.
