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.
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 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.
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.
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.
November 20, 2019 – Across the Arctic from Alaska to Greenland, in the remote places at the top of the world like Baffin Island, Southampton Island, and Melville Island in the regions of Nunavut, there is a small bird called the Lapland Longspur that spends the short breeding season courting, nesting, and raising its’ young. On the treeless tundra where packs of hunting wolves, Polar bears, and Arctic foxes eke out a living on the vast cold landscape, large migratory populations of Lapland longspurs, a small well camouflaged bird, begin arriving in the spring for the nesting season which starts by early June. These little ground nesting birds, that are about the size of a Song sparrow but with longer and more pointed wings, have a clutch of 3 to 7 eggs and only one brood. Their nests are constructed in a shallow depression lined with coarse grasses, mosses, and sedges. The nest itself is lined with finer, softer, materials from arctic plants and provides a cushioned place for the fragile eggs helping to keep them warm during the incubation period. After about 14 days, hatching begins and 10 days after that the young birds are able to leave the nest. The fledglings are equally divided and separately reared by each parent, according to the National Park Service. The time from nest to fully fledged is short in the arctic and soon the young longspurs will have developed their flight feathers and can forage on their own. As the summer comes to an end, the land of the midnight sun begins giving hints of the inevitable dark winter freeze. The Sun sinks low on the horizon as the calendar nears the Fall Equinox. By September, the longspurs are migrating south out of the dimming arctic leaving their breeding grounds for a less hostile and sunnier climate south of the Canadian boarder. By November, they are in the fallow crop fields and along rural roadways of Northern Illinois. Large flocks of these arctic birds can be seen feeding on spilled grain from the harvest. The little birds blend in quite well in the winter fields that are free of snow, but they frequently take to the air in a large flock flying and circling around only to return to the same spot. Foul weather with heavy snow brings the longspurs to the windswept or plowed edges along rural roadways where they find seeds and seek shelter from strong cold winter winds behind the tall drifts of snow. The Lapland longspurs will remain until late May fattening up for their springtime migration northward back to the breeding grounds of the high arctic.
October 31, 2019 – The Lincoln’s sparrow is a cautious little bird that doesn’t stray far from the safety of a partially obscured perch in a small shrub at the edge of the woods as it surveys it’s surroundings. The delightful little migratory visitor with its’ buff-colored chest and sides, cream-colored belly, and well defined dark streaks that run through those buffy areas, appears more light-colored overall than some of the other sparrows in and around the woods. The Lincoln’s sparrow has a finely detailed head with a brown, black, and gray striped crown, that sometimes in a moment of excitement, is raised into a crest. Compared to other sparrows, the Song sparrow for example that has more of a muddied color pattern, the Lincoln’s sparrow stands out like the new kid on the block because of those bold, sharp, streaked flanks, and the buff-colored chest that gives the bird an overall elegant appearance that easily captures one’s interest. The Lincoln’s sparrow is a rare winter visitor, according to the Illinois Department of Natural Resources, that winters from the southern United States south to central America. It is known to venture further than other similar species of sparrows during their winter migration which starts in September. The little sparrow has been recorded as far south as Panama in Central America,with one record apparently in northern Venezuela. The wandering Lincoln’s sparrow is reported every year during the winter months on the islands in the Caribbean. The northbound sparrow will make another appearance in Illinois in late April. Although records do show the Lincoln’s sparrow occasionally nesting in Illinois they are mostly known to nest in the boreal forests from northern Wisconsin across Canada and north into Alaska.
October 24, 2019 – The Dark-eyed junco is a small songbird that winters here in Illinois. The male of the slate-colored form of junco that we see here in the Midwest is dark gray with a very dark hood while the female’s feathers are lighter shades of brown and gray, but both the male and the female juncos have white outer tail feathers that are apparent when the birds are in flight. Juncos are a medium-sized sparrow that stand out against the snowy landscape looking somewhat like bouncing lumps of coal on a white sheet as they hop about scratching the icy snow-cover below the brown, dried-out plants vigorously searching for fallen seeds. The juncos are quite common at backyard feeders during the winter where they are regularly seen searching below the feeders with other foraging winter birds. Often called “snowbirds” the Dark-eyed Junco is a familiar sight along woodland trails during those cold months. The little birds are easily flushed to the the thick cover of leafless bushes were they can find protection in the dense shadowy web of dormant branches. During winter storms the little birds can seek shelter in those bushy thickets or quickly escape predators like hawks, foxes, and Bobcats when threatened. The Dark-eyed junco spends the summer during the nesting season in the northern United States and north of the boarder in most of Canada. They start arriving in Illinois during the fall migration in August for their winter stay. The spring migration can start as early as February. It seems, in my opinion, that there cannot be a more thought evoking snow covered winter scene, whether it is a first hand experience along a trail, conjured from ones’ memory, or displayed on a canvas washed by the artists brush, that doesn’t include those Dark-eyed juncos feeding with other winter wildlife on a dim gray and cold afternoon.
