The Brown Creeper

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.

The Ring-necked Pheasant

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.

Snowy Owl

A Snowy owl is perched on a utility pole this past week in Iroquois county.

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.

The Lapland Longspur

A flurry of Lapland Longspur’s burst into the air off of a snowy road in Iroquois county this past week.

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.

The Lincoln’s Sparrow

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.

Dark-eyed Junco

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.

The female (Slate-colored) Dark-eyed junco has much lighter colors of gray and brown.

Home for the winter

A first-winter White-crowned sparrow in Iroquois county this past week.

October 17, 2019 -It is that time of the year once again when we start seeing those attractive arctic breeders returning to Illinois for the winter. The White-crowned sparrow, with its’ dark black and bright white crown stripes and that distinct gray breast, stands tall in somewhat of a stylish pose while perched on a nearby branch. The sparrow disappears and reappears as it busily speeds through the undergrowth searching for food. An overgrown thicket with wild fruits, seeds, and plenty of insects and protection from the weather and the predators, like hawks and falcons, is an ideal winter home for the White-crowned sparrow. The first-winter birds do not have the black and white crown but they stand out nonetheless in their new sharp looking feathers of a reddish-brown and gray raised crest and their pinkish bill, a youthful look that remains until spring. The White-crowned sparrow is a tall elegant presence compared to our darker drab colored resident sparrows that we oftentimes take for granted. With the exception of White-crowned sparrows in the northwestern United State that are considered resident or medium-distance migrants, most nest from from St. Johns bay north above the arctic circle, east to Newfoundland, and west to Alaska. According to the Cornell lab of Ornithology, “birds along the Pacific Coast and in parts of the interior West don’t migrate”. Illinois is the northern most part of the the White-crowned sparrows winter range which extends as far south as central Mexico. The fall migrants start arriving in numbers from the north in late September and October. The birds that wintered farther south and are migrating north in the spring start showing up in May as they work their way towards Canada.

Those Wrens

A Carolina wren pauses for a moment on a branch near some feeding sparrows.

October 10, 2019 – The mostly drab and well camouflaged light brown House wren, or the glamorous Carolina wren with its’ rich reddish brown over pale brown tones with distinctive white eyebrows, makes those two wrens easy to recognize. The House wren and the Carolina wren are two of the five common wrens we find here in Northeastern Illinois. The House wren, like the Carolina wren, is a small bird with a big sound system. Their songs are most often noticed before the birds are ever located and sometimes those clear rich sounds are both baffling and uplifting to the observer when they witness such small birds with very large and impressive songs. The little House wrens build their nests in the holes and cavities of living and dead trees. They will use nesting boxes, holes in buildings, or abandoned machinery, if it provides just the right sized hole and offers protection from predators and other birds. Carolina wrens will use tree cavities, flower pots, tree stumps, overhangs, tin cans, or thick vegetation for nesting. The poet William Wordsworth’s poem “A Wren’s Nest” describes quite well, in his inspiring verse, the competence of the nesting wren and their choice of the perfect nest location. The Carolina wren prefers thick bushy overgrown areas of habitat. The House wren also likes similar habitat as the Carolina wren but is just as happy in yards and on farms that offer places to nest and find food in and around farm buildings and brush piles. The House wren is a short to medium-distance migrant that spends the nesting season in the northern two thirds of the United States and into southern Canada. It winters in the warmer climate of the southern US and Mexico. The Carolina wren is a year-round resident in the eastern United States from the southern great lakes to the eastern seaboard, south to Florida, west to east Texas and south into Mexico.

Fall Migrants

A first winter Chestnut-sided warbler comes into view for a moment to perch on a nearby plant.

September 26, 2019 – On any morning this time of the year the subtle seasonal changes seem to bring, to those who are willing to show patients and perseverance while keeping a watchful eye, an exciting surprise of another species or two of warbler that can be noted, as those little fall migrants work their way south. A wooded area with brushy, dark-shadowy cover that is loosely bordered with well seeded weedy plants and an abundance of insects that live among them, can appear almost void of any birds except for those resident feathery inhabitants that have been there all summer. But during the night things can change quickly as new arrivals, from the north, find a place to rest and recharge or wait for better weather. Through the dim morning light in the thick dark green and black understory a sudden movement with a flash of color catches ones eye, there are a small number of male and female American redstarts that have just arrived. Working their way through the thicket vanishing at times, they would quickly reappear checking each leaf and branch for insects with a quickness and a gentle fairy-like lightness as one of the little birds would hover in mid-air to get a better vantage of the underside of a leaf. In the fork of a tree where it is clearly wet with sap, a few Tennessee warblers are clinging from different angles while feeding on the insects in and around the wet spot. In the nearby elm, higher up in the canopy, adult Bay-breasted and first winter Chestnut-sided warblers move from leaf to leaf looking for insects. The adult Bay-breasted male, now in his non-breeding plumage, still shows the glorious rufous color on his flanks. Common yellow-throat and Magnolia warblers unexpectedly pop into view on the sunny side of the thicket only to disappear within seconds. The fall migration of warblers can be just as exciting as the highly anticipated spring migration and well worth keeping an eye on those woody areas and green spaces in the parks and along the creeks and rivers.

Wich-i-ty, Wich-i-ty, Wich-i-ty

A Juvenile male with a developing black mask pauses on a stem as he moves through the undergrowth.

September 19, 2019 – Common yellowthroat warblers are a summer visitor during their nesting season here in northern Illinois, across all of the United States, and most of Canada. A first winter male Common yellowthroat can have a faded black mask from July to March while the adult males have a stunning coal back mask with a white border across the top of the mask and a bright yellow throat that extends down the chest. The flashy little males can stand out in contrast of their habitat at woody edges of a marshy thicket. The small warbler sometimes give away their location by the clear and rapid song of wich-i-ty, wich-i-ty, wich-i-ty. Often though, the little bird appears without notice clinging to one side of the rigid stem of a cattail or other suitable plants, pausing momentarily before disappearing into the thick undergrowth searching each leaf and stem for insects. The female Common yellowthroat have a pale yellow throat and they lack the black mask and white headband of the male. The muted colors of the female yellowthroat are beautiful tones of brown, gray, and olive-yellow. The nesting Common yellowthroat put their nest in thick growth well hidden and low to the ground. The parents drop down into the nest area but always leave from a different route to fool potential predators. After the nesting season, by November the little birds have gone south for the winter. The little warblers will return to our area of northern Illinois in the spring and are here in numbers by April. The Common yellowthroat is a Neotropical warbler that winters in Mexico and Central America, with non-migrating permanent residents in the southern coastal areas of the United States and western and central Mexico.
