The Changing Light

October 7, 2023 – That old familiar change is in the air as fall arrives. The cooler nights provide a restful sleep and easy dreams as open windows bring a gentle breeze replacing noisy air conditioners. The changing light and long shadows give a new look and feel to a tired countryside. Even though the gardens and prairies still have plenty of nectarous blooms for the pollinators while adding color to the glorious landscape, many plants have gone to seed and are showing signs of wear and tear as they begin to reveal the yellows and oranges of autumn. It is that time of year before the ice and snow that summer residents migrate south. Many species of birds are on the move coming south from the higher latitudes, while others are preparing to move south by gorging on nature’s bounty of seeds, nectar, and insects, building up their fat reserves for their challenging journeys. Monarch butterflies, Common green darner dragonflies, and even Eastern red bats are taking to the skies and are heading to a warmer climate for the winter. Long-distance migrants like Broad-winged hawks have recently been photographed in the area working their way south towards Central and South America, where they will wait for spring near the equatorial latitudes, wisely retreating far away from those cold north winds. Large, bright white, wading birds, the Great egrets, stand out against the changing colors as they feed in the backwaters of the Kankakee. Hunted nearly to extinction in the late 1800s for their beautiful plumes, new conservation laws in the early 1900s implemented to protect birds are why we see the Great egrets today. While there are always a few egrets that stay in Northern Illinois through a mild winter, most of the summer population of Great egrets in the lakes and marches of the Great Lakes region will have gone as far south as Central America for the cold months. In the coming weeks, large flocks of Sandhill cranes will be in the air over Northern Illinois and Indiana as they have done for thousands of years. The Sandhill crane population has rebounded over the years from the low numbers of only a few dozen in the 1930s thanks to protective laws; today, we enjoy the sites and sounds of the cranes in migration, those bugling rattles that demand one’s attention, are a sampling of the bygone days before the Europeans expanded into North America, where they nearly wiped out the Sandhill and Whooping cranes forever. Shorebirds, wading birds, raptors, songbirds, and waterfowl travel through Illinois during the fall migration, some spending the winter in the state. Backyard feeders are a great place to monitor during the fall migration; watching and listening for those unusual migrating songbirds is an exciting and rewarding moment when one witnesses an uncommon fall traveler that probably goes unnoticed by most.

Bitterns

June 10, 2023 – More often heard than seen are those secretive herons of the marshlands, the American bittern, and the smaller and less common Least bittern. The peculiar calls of the American bittern remind one of the sounds of liquid pouring from a large jug with a small neck and have been aptly described as a repeating oonk-ga-chonk, oonk-ga-chonk, earning the bittern nicknames like mire-drum, thunder-pumper, and stake-driver. The American bittern has a status in Illinois as an endangered native, and the loss of wetlands has reduced nesting habitat and contributed to the decline of this species over the years, which continues even today across its range from pollution, climate change, and habitat loss. The Least bittern is about half the size of the American bittern at about 13 inches, making it the smallest heron in the Americas. The little heron is listed as threatened in Illinois, suffering from the same environmental challenges as many wetland birds. The smaller bittern has several calls that are familiar sounds in the marshes and bogs with shallow water and tall cover, high-pitched clucking, and springtime mating calls of coo-coo-coo-coo heard in the wetlands are sometimes mistaken for the sounds of frogs or the songs of other birds like the Black-billed cuckoo. Once a common summer bird in Illinois, their decline began with a reckless assault on the land in the late 1800s. The destruction of wetlands by the draining of shallow lakes and ponds that once dotted Northern Illinois had a devastating impact on the local and migratory wildlife. With the encroachment of man determined to tame the land for other uses, the Least bittern is now seen or heard only in the limited areas of its favored habitat. Traveling at night during the migration Least bitterns begin arriving from Central and South America in April. The little herons build their nests among the tall, dense vegetation, where they interweave a platform above the water from dead plants. They will produce four or five eggs with two broods each year. Spring migration of the American bittern starts in March and April, and this might be the best opportunity for a lucky person to get a glimpse of this secretive and well-camouflaged bird. Although nesting does occur in Illinois in the limited marshes and sloughs, the American bittern is considered an uncommon summer resident. More widespread nesting occurs in the vast dense wetlands of our northern border states, continuing into southern Canada.

Clinging tightly to the long stems of reeds, the Least bittern blends in quite well as it slowly works its way through the dense growth.

Warmer Days

April 8, 2023 – Early spring here in the Midwest sometimes seems like nature has problems making decisions. Warm days cool nights, and even snow and freezing temperatures keep eager gardeners on their toes as they prepare their plots and bestow excessive care on their new trays of spring plants while impatiently waiting for the frosty nights to go away so they can start a new season of splendor for the senses and nourishment for the pollinators. Emerging Insects, spring wildflowers, and migrating waterfowl are encouraging signs that the weather will comply sooner rather than later. Many feathered migrants have already arrived in the area for the nesting season others are staging here, building energy and fat reserves in the safe areas of refuge until the time is right to push further north toward their nesting range. The large flocks of noisy Greater white-fronted geese in the backwaters and flooded fields during the night began flying out in the early mornings to forage on spilled grain in the nearby ag fields. There are species of ducks, grebes, and swarms of coots in the flooded cover of the sloughs this time of year as the backwaters begin to ripple with life. Diving ducks, Buffleheads, Scaup, and Hooded mergansers are out in the open water bobbing on the waves, occasionally disappearing below the surface to search for food. Male Red-winged blackbirds have claimed their perch near some possible nesting sights; the males display their flash of color while continuously singing songs of love trying to attract a mate along the rural roads near ditches and around the wetlands. Tree swallows are long-distance migrants and are back in our area tired and hungry from their travels. The swallows arrive back in Northern Illinois in March when the weather can be more winter-like and pose a challenge for these migrants. Flocks of the graceful birds glide and circle just above the water in an attempt to catch small insects, often dipping down and skimming the surface for a quick drink. Another highly anticipated springtime migrant is the celebrated summer resident, the Eastern Bluebird. Bluebirds spend winter in the southern parts of Illinois to the southeastern coastal areas of the United States and begin arriving in Northern Illinois for the nesting season in February. Appearing as if dipped in lovely powdered pigments of eye-catching blue over pale orange-brown, one cannot deny the beauty of Eastern bluebirds in the spring perched on fence posts or the branches of a small tree at the edge of an open meadow. The bluebird brings joy and inspiration to poets, lyricists, and illustrators of nature and also for the cultivators and casual observer a reassurance that the warm days of springtime are near.

The colors are not as intense on the female Eastern bluebird as they are on the male but still she is a very attractive bird.

Open Water

Four Trumpeter swans, one adult, and three juveniles on a snowy morning in a flooded field of corn stubble at the Willow Slough Fishing & Wildlife Area.

February 10, 2023 – A light and steady snow floated out of the chilled gray January sky onto the open waters along the Illinois-Indiana border. Hundreds of Greater white-fronted geese and a small number of Tundra and Trumpeter swans here for at least part of the winter were resting and feeding. The flooded, unfrozen fields of corn stubble at the Willow Slough Fishing & Wildlife Area in Newton County offer a perfect resting area for these wintering waterfowl waiting for spring. A family of Trumpeter swans, two adults, and three first winter birds feeding nearby were beautiful subjects on such a dream-like morning. Enhanced by the sounds from the large flocks of Greater white-fronted and Canada geese, the scene couldn’t have been any better. The lighting was near perfect, and the snowfall provided an unusual photo opportunity for these large elegant birds. Having a six-foot wingspan and a weight of up to 26 lbs, the Trumpeters are North America’s biggest waterfowl and are twice as heavy as our other native swan, the Tundra swan. Spending some time observing and photographing the trumpeters as they fed, preened, and occasionally expanded their magnificent wings making powerful and load-flapping sounds that carried for some distance, was an unusual and exciting opportunity to watch at close range the behavior of the swans. Standing motionless behind the camera and tripod for quite some time, I watched them as they fed together, stretching their long necks down into the cold water, searching the submerged vegetation for the much-needed nutrition required by wintering waterfowl as they prepare for the spring migration. Feeling fortunate as I observed these beautiful swans and knowing that there was a time in the 1930s only 69 trumpeters were known to biologists in the lower 48. Although small pockets of surviving birds were discovered in Canada and eventually a few 1000 in Alaska, it took some acts from the government to put some protection on these birds. That dedication to protecting the swans continues today through the laws of the states and the federal government, combined with educating the public about the rapid downfall of the Trumpeter swan from the market hunters and habitat loss in the late 1800s and early 1900s that nearly eradicated the swans from the United States. Recovery of the Trumpeter swan population continues with the ongoing efforts to expand their habitat while fighting against other factors that negatively affect the swans, like climate change, pollution, and lead poisoning from lead ammunition and lead fishing weights. Biologists, citizen scientists, and volunteers take on the challenges with a dedication to protecting and expanding quality nesting and wintering habitat while monitoring the North American population of around 63,000 Trumpeters. Those results are a true testament to the success of the combined efforts of many individuals with a powerful commitment to save the Trumpeters. It also must be realized that all the hard work and progress made from helping the Trumpeter swan is most certainly having a positive impact on many other wetland species.

The Butcher Watchman

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.

Swallow-tailed kite

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.

The Sora Rail

An adult Sora with its’ bright yellow bill searches for food on the muddy exposed area at the edge of some cattails.

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.

The Green Heron

An adult Green heron flies across the shallow end of a small lake landing on some vegetation where it soon began hunting in the ankle-deep waters.

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.

Goodbye Winter

A male Ring-necked Pheasant searches for food through a small opening in the melting snow.

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.

The American Kestrel

Hovering into the wind above an open grassy area along a creek in Iroquois County a beautiful male American Kestrel falcon searches for prey.

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.
