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.
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.
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 18, 2019 – As springtime advances and the migrants move north, Turkey vultures, those masters of the air currents, are once again gliding across the skies of Northern Illinois in large circling flocks that are sometimes referred to as a kettle. Even though a few of these large dark colored vultures are spotted in northern Illinois during the winter months, most migrate south in the fall after the nesting season. They spend the winter from Southern Illinois and across the southern United States, south through Cuba, Mexico, Central and South America and as far south as ‘the end of the world’ Tierra del Fuego in southern Chile.
North America has three of the six subspecies of Turkey vultures. Cathartes aura septentrionalis is found in the eastern United States.(Palmer, 1988) With a wingspan of around six feet these large slow flying birds are hard to miss as they fly off of the carcass of the unfortunate roadkill as a vehicle approaches. Those close encounters certainly gives the observer an appreciation for the impressive size of the Turkey vulture. They usually don’t go far when flushed from the carrion and soon return to their feeding when the threat is gone. They are often seen still on their roosts in dead trees, utility poles or buildings early in the morning. With their wings spread wide like a parabolic antenna while facing the warm morning sun they are warming their bodies and drying their feathers from a rain shower or the dampness of the night.
Nesting Turkey vultures will use the abandoned nest of other large avian species in secluded areas far from human traffic. They will also use old sheds, barns, and houses that are remote, grown-up, neglected and open to the elements. The Turkey vulture may choose to lay their clutch of 1 to 3 eggs in a nest on the ground that they scrap out in the leaf litter in a dense thicket or near a fallen tree or even in a hollow log. The vultures will have only one brood over a 60-84 day nesting period and may return to the same nest year-after-year according to The Cornell Lab of Ornithology, All About Birds. Palmer, R. 1988.

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.
December 9, 2018 – Perched on a steel cable above a grassy area a Rough-legged hawk, a large raptor of the high arctic during the summer, keeps an eye out below for prey. The photo shows the feathers covering the legs, extending down to their small feet. The tip of the beak is stained red from a recent kill. The Rough-legged hawks have migrated south out the Arctic and are now on their wintering grounds. The wintering ground of the Rough-legged hawk includes most of the United States, minus the states south of the Ohio river and East of the Mississippi. According to The Cornell lab of Ornithology these wintering hawks feed mostly on voles, mice and shews while in our area of Illinois. I have personally witnessed them on the carrion of a rather large mammal a few winters back. With a wingspan of over 4′ they can’t be missed as they hover and glide over the farm fields and prairies. Watch for them perched on utility poles or on the small branches of trees or even sitting on the ground throughout the winter months.
October 15, 2018 – A southbound, migrating Palm warbler in its’ autumn drab blends in quite well as it finds the perfect perch to quickly survey the surroundings. The Palm warbler is known for its’ tail-wagging and this one doesn’t disappoint, showing off those bright yellow feathers under the tail. In an instant though, the little bird is off to continue its’ hunt for insects or seeds among the tall, dried vegetation.
September 13, 2018 – A female Common Yellow-throat warbler pauses for only a moment atop some dried thistle standing at the edge of the thick undergrowth. Quickly the little bird vanishes into a maze of green as she searches for insects on top and below every leaf she encounters, at times revealing her location as she flutters from branch to branch in her quest.
July 22, 2018 – The dragonfly has had its’ place in the myth and symbolism of humans for thousands of years, both good and evil has manifested in the folklore and the art of both prehistoric and modern humans. From the primitive cave paintings to the Art Nouveau dragonfly pendants there is no denying that their beauty is an inspiration. Their evolution began over 300 million years ago, as some fossil records show amazing giant dragonfly like insects with wingspans of over two feet. But from a different path millions of years ago our modern dragonfly evolved. The modern dragonfly is much smaller, the largest dragonfly in North America is the Giant Green Darner of the Southwest that has a wingspan of around five inches. Here in Illinois we have the Common Green Darner that looks similar to the Giant Green Darner but it is a little smaller with a wingspan of a little over three inches. The photo shows the Common Green Darner clinging to a corn stalk leaf where many others were feeding along a grassy road in rural Iroquois county.
June 26, 2018 – Along the uncut rural roadsides and in the meadows where the butterflies go, along the creeks and over the sparkling waters of ponds, the delightful summer air is in motion with dragonflies of many shapes and sizes with a variety of color patterns. Halloween Pennants, Common Whitetails, Eastern Pondhawks, Widow Skimmers and other species like the Twelve Spotted Skimmer which is found throughout the U.S. and southern Canada is shown in the photo perched on a dried weed in Iroquois county. Mostly unnoticed or ignored, dragonflies can only really be appreciated for their unique beauty and color patterns when seen through binoculars or a camera zoom.
