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.
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.
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.
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.
August 5, 2019 – As we are coming to the end of August one can not help but notice the changes that are happening as another autumn nears and summer contemplates its’ well earned rest. The changes that have been a bit subtle are now upon us. The angle of the sunlight brings an inspiring warm tone to the landscape. The gentle breezes swirling through the forest canopy rustles and rattles the matured leaves allowing us to hear those uplifting whispers of the mighty Cottonwood. We have come to that time of the year where there is a bounty in the northern hemisphere for the avian migrants and those birds that are here year-round. Recently fledged birds, along with the adults, are fattening up for the migration, checking every leaf, stem, and branch for insects and worms. Little Blue-gray gnatcatchers, Warbling vireos, and Chickadees are persistently looking over and under every leaf while they cling tightly to the stems as they feed. Thistle and other seeds, berries, and nectar are available for the birds that are coming south from the higher latitudes as well as the birds that have nested here in Northeastern Illinois.
Prothonotary warblers stand out with their bright yellow feathers and olive-gray toned back and wings while gobbling up caterpillars with amazing success as they pluck them off those woody plants at the waters edge. Goldfinches are on the beautiful purple blooming thistle plants along roadways and on the prairies searching for the high fat and protein rich thistle seeds. Adults and this years’ young Hummingbirds stake out and fearlessly defend, from a good perch, their abundant food source, a large thick patch of Orange Jewelweed surrounded by other nectar giving plants. Some of these travelers will be around for a while feeding and fattening-up and growing strong for either a long or short migration. As the weeks go by though, and those abundant food sources in our area start to wane, the north wind bringing cooler temperatures, many birds will leave our area in a final push and continue south where they will spend the winter in a warmer climate.
July 18, 2019 – The adult Barn swallows are sleek and swift with vibrant colors and long forked tails, they are both elegant and beautiful in flight or perched. The American Barn swallows are long-distance migrants and spend the nesting season in most all of the United State and north into southeastern and northwestern Canada and into southern Alaska. The swallows winter in Central and South America. Barn swallows are seen here in Illinois during their nesting season. Most often they are noticed in large numbers around open farm buildings where they build their nests in the rafters and eaves. They also use large and small bridges where they build their nests in the underneath structure of the bridge supports. The swallows construct their nests out of wet mud and grasses forming them into a half cup shape in the relative safety of the man-made structures or natural shelters like cliff overhangs.
These medium size birds fly up and down the creeks and ditches and across open areas zigzagging in confusing maneuvers as they hunt for insects. The young are brought food, usually large insects, while still in the nest or as fledglings perched together near the nest site. Their little bright yellow beaks all pop open at the same time like little beacons as their heads move in unison following the adult birds as they fly by. The adults seem to know who’s turn it is eat next when they return with a plump insect. Folklore and religious tales relating to the Barn swallow have endured throughout the ages. It is said the Barn swallows bring good luck if it nests on your farm but removing the swallows nest would bring bad karma to the farm. It is also said that the Barn swallow brings us the good news, with their chatter, that summer is on its’ way.
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.
May 30, 2019 – Flycatchers have returned to northern Illinois for the season. They are most often seen perched at the edges of wooded thickets, along rural ditches or open areas near ponds, creeks, and meadows waiting for insects to take to the air. Patiently perched on a tall sturdy dried stem from last years growth or on a limb of a fallen tree, the mostly drab colored little birds can quickly fly off their perch and grab insects in midair or pluck one off a nearby leaf. They detect the slightest movement from a walking or flying insect with their keen vision.
Consuming their prey promptly, the flycatcher resumes focus on their surroundings, watching for prey from a satisfactory random perch. Small crawling and flying insects such as beetles, leafhoppers, and dragonflies are a few of the types of insects that the flycatchers feed on. Some flycatchers, like the Eastern Kingbird, primarily feed on insects early in the season while in their summer range here in Illinois, but wild fruits become part of their diet as this supplemental food source becomes available later in the season. During the months that the Eastern Kingbird spend in the western Amazon basin in South America fruits are a main food source for these birds.
Like many of the other traveling birds we see during the spring migration and during the nesting months here in Illinois, the flycatchers migrate north from the southeastern coastal areas of the United States and southwest into Mexico, Central and South America. While some nest in the United States others continue north into Canada and Alaska, like the Alder flycatcher for example that has a large nesting range and breeds in the area of the Great Lakes in the United States, and most of Canada and Alaska. Some of the more common flycatchers we see during the summer nesting season in Northern Illinois are Eastern wood-Pewee, Great-Crested Flycatcher, Eastern Phoebe, Least Flycatcher, and the Eastern Kingbird.
April 5, 2019 – The soft songs of the American Tree Sparrow are like a pleasant melodic whispering that easily causes one to momentarily pause and focus. This medium size sparrow can be seen at times singing from a low perch on a bush or while foraging on the ground at the edge of a thicket. Winter flocks of these little rusty capped birds have been gathering, feeding, and building energy while waiting for that moment during their spring migration when they take their night flight north towards the Arctic tundra of Canada and Alaska.
As days begin to grow longer metabolic changes occur that help prepare the birds for their long flight. According to the Cornell Lab of Ornithology, a huge increase in appetite helps to build up fat reserves that are required for such a physically demanding journey. Both internal and external factors play a role that triggers the big push north for the nesting season. Weather conditions are important so as to coincide with insect hatching in the stopping areas along the migratory route.
One can only imagine what it would be like to be part of a flock of a few hundred small birds on a cool, crisp starry night flying towards that shimmering fiery glow of the auroras above the northern latitudes. Those little sparrows face many miles and a number of challenges as they work very hard to reach their nesting grounds north of the tree line where the Arctic fox, the polar bear, and the ptarmigan call home.
