The Golden Eagle

A 4th year sub-adult Golden Eagle south of the Kankakee river this past week. The bird’s golden feathered head clearly visible as it flies out from a perch and glides over the winter landscape.

February 13, 2020 – Here in the Midwest it is now a common sight to see Bald eagles gliding high above the flat terrain of Northeastern Illinois and Northwestern Indiana. Nesting Bald eagles are also a more common occurrence in Illinois and Indiana, a remarkable rebound since the ban on DDT’s agricultural use in 1972. Illinois estimates indicate well over 300 active nests and for the state of Indiana a 2016 estimate shows close to 400 breeding pairs. Most often we see a magnificent Bald eagle or even a few of these great birds perched in a tall snag above open water along our rivers here in the Midwest, especially during those hard winter months. The eagles sit patiently waiting and watching while hunting ducks, coots, and fish or any other food opportunity that might come along. There is another species of eagle, the Golden eagle, that is less common and only seen or noticed by a lucky few during the fall and spring migrations. The Golden eagle may also be seen during the winter months in locations that provide open spaces, forests, and abundant prey. This winter a pair of Golden eagles were recorded in Iroquois county where they were photographed by bird enthusiast and nature photographer Bronson Ratcliff of Bourbonnais. Having a pair of wintering Golden eagles in our area is an exciting discovery. The Golden eagle nests across Canada and Alaska and in the mountainous western United States. They are year round residents and nest on the high cliffs and steep slopes with a open views throughout the Rocky Mountain states and west to the Pacific.
Here in the Midwest we watch for these large dark birds during the migrations. They are easily confused with Turkey vultures, Juvenile Bald eagles, or any large dark raptor. The 1st year juvenile Golden eagles have bright white tail feathers except for 2 or 3 inches of the tips which are dark brown. They can also have bright white patches on the tops and bottoms of the their wings from the middle of the wings out towards the ends, and are easy to see during flight. The 1st year bird is probably the easiest to identify with those good solid markings, but as they age, those bright white feathers start to fade as they get their adult feathers and other indicators must be looked at. The gold feathers on the back of the head and nape of the neck is another obvious clue that is easy to spot. The two tones of light and dark feathers on the head and neck, even on a perched bird in the shadows of a tree, stand out. The Golden eagle also has a shorter neck and smaller bill than the juvenile Bald eagle. Another comparison is the Golden eagle has feathered legs that go down to the feet and the Bald eagle does not. Next time you see that large dark raptor soaring above, look a little closer, it may be a Golden eagle.

Wintering Cranes

A small group of Sandhill Cranes lean into the wind preparing to take to air.

February 6, 2019 – The amazing sounds of wintering Sandhill cranes echoes out across the chilled and colorless January landscape of Northwest Indiana. Uncertain to the exact number of cranes that have spent their winter in the general region of the Jasper-Pulaski Fish & Wildlife Area this year, I was told by a local resident that he would guess maybe as many as 10,000. I am not sure about that amount, but I can say with a bit of certainty that I did observe a few thousand birds in and around and above the agricultural fields as I meandered through the back roads of rural Indiana this past week. The Sandhill cranes that stop short of their southern migration and remain in northwest Indiana throughout the winter take advantage of the open waters in the marsh at Jasper-Pulaski state park during a mild winter. They also use the shallow waters of the cooling lakes at the power plant just northwest of the state park. When the winter is more severe and the marsh is frozen the cranes are more numerous near the power plant . At night the cranes roost in the safety of numbers, while standing in the shallow waters of the cooling lakes, in relative comfort during those cold winter nights. The cranes, this past Friday, were flying out to the fields joining large flocks that were feeding and socializing when I arrived to the area at about 9am. Last winter at the end of January when the air temperature dropped down into the negative 20’s the cranes did not leave the cooling lake for the surrounding fields until almost noon. The steam from the lakes and the tall stacks at the plant produced huge white billowing clouds that became a backdrop to the thousands of cranes in the sky braving the elements flying out to the frozen fields of corn and bean stubble. This sight of the cranes flying in such an extreme weather event made it clear to me that hardy is an understatement for this ancient species.

Trumpeter Swans

January 30, 2010 – A pair of Trumpeter swans surrounded by a number of Canada geese and a a few Mallard ducks were taking advantage of the open waters near the boat docks at the headquarters at the Willow Slough Fish and Wildlife Area near Morocco Indiana this past week. A submerged aerator system sending bubbles of air to the surface keeps some small pools open and ice free. The open water attracts waterfowl during the winter when the rest of J.C. Murphey Lake is locked in ice. Getting a close look at the pair of swans, that have been seen at the lake for some months now, show that one of the birds does not have the usual black legs and feet that is normally seen on an adult Trumpeter. While photographing the Trumpeters at some distance this past August I noticed the yellow colored legs on one of the birds and assumed it was a juvenile. I was told at the headquarters at Willow-slough this past week that the swan with yellow legs was believed to be leucistic. Leucism is a genetic mutation that causes a reduction of pigments. We see the abnormality in mammals, birds, and even in reptiles. A few times a year while great flocks of Starlings are feeding in fields it is not uncommon to see a flash of white from the wings, tail, or the head of one of the birds in the flock. The birds with white feathers are missing the normal dark colors of the Starling and are considered leucistic. The young cygnet (baby swan) that is leucistic is bright white and the non leucistic young Trumpeter is gray. The leucistic birds end up with yellow legs and feet as adults Trumpeters. These rare leucistic Trumpeter swans have been reported and are still occasionally seen in Ontario. The leucistic swans are bit more common in the Rocky Mountain population and are also seen in the Yellowstone summer population.

The Pigeon Hawk

Just east of Kankakee recently, a Merlin falcon looks down from its’ tree perch watching for an ambush opportunity.

January 23, 2010 – The Merlin falcon is a small but fierce hunter that is a little larger and heavier than the American kestrel. Looking somewhat like a chunky pigeon in flight the Merlin was once known as the pigeon hawk. The stealthy falcon lacks the bold color patterns and black “mustache” that adorns the face of the more common Kestrel. The Merlin’s may show a faint “mustache”, the black plumage on the sides of the face, but the bird appears a bit drab overall compared to the smaller and more colorful Kestrel. The female Merlin, like other birds of prey, is larger than the male. A large female with a recent catch of a small bird was facing away from me as it sat on a roadway in Iroquois county a few years back. From a distance the bird looked like a small Peregrine falcon, its’ solid blue-gray back and wings stood out and its’ thick body confused me at first until the bird took to the air with its’ prey. At that point I recognized it as a Merlin. The little Merlin is an avian hunting master that can send a flock of birds into a mass of fear and confusion. Outmaneuvering the unfortunate winged victims like Starlings, Sparrows and even small ducks, the Merlin,with a swift and precise attack snags its’ targeted prey while in flight. It also plucks dragonflies and other insects out of midair during its’ migration for a quick and easy snack. If you are fortunate enough to see a Merlin in our area of Northeastern Illinois it will most likely be during the winter months but sightings of the Merlin are becoming more common as the population of the little falcon has improved. The Merlin is known to breed in the boreal forests of the north but the discovery of a hatchling on the ground in Northwestern Cook county in 2016 may signify that they are expanding their breeding range.

Rough-legged Hawks

January 16, 2010 – Imagine looking out over a vast expanse of rolling and rocky terrain that stretches as far as the eye can see. Off in the distance you notice, from your high vantage atop a narrow rocky ledge on the southern slope of a mountain, an Arctic fox with its’ nose to the ground as it zigzags in a slow but deliberate trot across the tundra. At times the little fox disappears behind the slight rises of the uneven landscape and soon goes out of view completely. Further out towards the west is the unmistakable and heart stopping sight of a large white predator. A hungry Polar bear is walking with large, intimidating strides along the edge of an Arctic pond, surprising a pair of skittish Eider ducks. The birds quickly begin paddling away towards the center of the pond putting some distance between them and the dangerous intruder. Those sights that we just imagined could be the very real views that the nesting Rough-legged hawks might see while they spend the warmer months in the high Arctic paired up, nesting, and raising their young. The Rough-legged hawk is one of a small number of moderate-distance migratory hawks that we are fortunate enough to see here in Northeastern Illinois during the winter. These amazing hawks will find a good hunting spot, open terrain similar to that of the Arctic tundra, where there is plenty of prey with not much competition and most likely stay in that same general area for the winter. The open agricultural areas and restored prairies of Northern Illinois and Northwestern Indiana are great places to find these large hawks hunting. The plumage of the Rough-legged hawks can differ, some birds are very dark and some are light in color. They are referred to as a dark or a light morph. The Rough-legged hawk will take advantage of windy days and hover into the wind to hold their position above the prairie while hunting mice, voles, and birds. Fence posts, utility poles, and the smaller branches in the tops of trees where they can grip with their small feet are places the hawks will use to watch for prey.

Bucks And Toms

A rare look at a giant White-tailed buck out in late morning with a doe during the rut this past November in Iroquois county.

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.

The Brown Creeper

A Brown creeper probes with its’ long curved bill behind the bark of a tree looking for insects.

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.

Short-eared Owl

December 23, 2019 – It’s the most wonderful time of the year, that time when winters’ late afternoon skies become active with Short-eared owls swooping, gliding, or perched on a fence post or in a small leafless tree just above the tall grasses of their winter roost. Early mornings and overcast days are also good times to see the owls. Where suitable habitat exists on the restored prairies or along the rural roads of Northeastern Illinois and Northwestern Indiana during those cold winter months, it is during the late afternoon, as the sun retreats towards the southwest, when those delightful medium-sized owls take to the sky in amazing displays of flight. When not chasing each other, in their minor territorial disputes, they search the fields and prairies for prey, occasionally landing on the ground highly alert and watching the other owls flying above. When “The Prairie State” was truly a prairie, before settlements and agriculture claimed the land, the nesting of Short-eared owls was believed to be widespread and numerous on the unbroken grasslands of Illinois and Indiana. Now there are only a few places suitable for nesting in Illinois. Prairie Ridge State Natural Area in Jasper County is one of those areas and it provides 2000 acres of grassland habitat for these ground nesting owls to roost, hunt, and fledge their young. It should also be mentioned that the 2000 acres at Prairie Ridge has nesting Northern harriers and the states only population of Greater prairie chickens. Closer to home, just east of Kankakee, the 8,400 acres of restored prairie and wetlands owned and managed by the Indiana Chapter of the Nature Conservancy at the Kankakee Sands in Newton County Indiana is a great place to observe wintering Short-eared owls, Harriers, and Rough-legged hawks.

The Northern Harrier

A hunting Northern Harrier spreads its’ tail-feathers slowing down quickly to catch the prey below.

December 19, 2019 – Gliding low and slow across the agricultural fields and the grassy waterways and prairies here in Northeastern Illinois are the beautiful Northern harriers. Once known as the Marsh hawk, these steep banking, quick stopping, hunting birds are considered here in the United States as “resident to long-distance migrants” According to the Cornell Lab of Ornithology. We see an increase in numbers during the fall migration and into the winter months throughout Illinois. The harriers nest in numbers from Northern Wisconsin north into Canada and Alaska. These ground nesting hawks require large amounts of grasslands or wetland habitats for successful nesting. Some of the harriers winter from just south of the southern edge of their summer range, while others migrate all the way south to Central and South America. The stealthy, medium-sized hawks can be seen flying and hunting across Illinois’s cold sleeping landscape, looking and listening for movement coming from the dried dormant grasses just beneath their silent glide. When the focused hunters detect prey they use their long wings and long tail feathers to quickly turn and stop their graceful forward movement and instantly drop down on a field mouse or vole. The harriers are often seen diving at and chasing away Rough-legged hawks, Red-tailed hawks and even other harriers that get too close to their perceived hunting areas. The Northern Harriers are easily identified as they fly low across fields and prairies, their wings most often in a v-shape, and there is a white rump patch at the top of their long tail feathers. The female harriers and the immature birds are dark reddish-brown and tan, and the male adult birds, slightly smaller than the female, are a light-gray and almost white on some parts of the body, the tips of their wings are black. Often perched on a fence post or sitting in a field with a captured prey, one can get a good look at the feather pattern on the harrier’s face, it has a round appearance and resembles that of an owl. The disk like pattern of feathers on the harriers face is believed to help the hawks hear their prey as they hunt.

The Ring-necked Pheasant

A male Ring-necked pheasant gives a broadside look a those glorious tail feathers.

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.
