May 21, 2018 – A yellow and olive colored Wilson’s warbler with its’ tiny black cap holds fast to a small branch as it momentarily surveys for the next stem to continue its’ hunt for insects. Quickly moving through the understory it disappears for a time. Emerging out of the shadows the small bird hovers at the edge of a bush to catch its’ prey. The little warblers only give brief glimpses, lingering at any one branch for mere seconds, a flitter perhaps to the observer but with a definite purpose to the tiny bird. Wilson’s warblers are a very small warbler, only slightly larger than a Ruby-crowned Kinglet. The little warblers migrate through our area of the Midwest heading north into Canada for the nesting season from their winter home on the Gulf coast from Louisiana, Texas, Mexico and Central America.
May 22, 2018 – The Yellow-warbler is considered an early long distance migrant that winters along the coasts of Mexico, the interior of Central America, and south to the equatorial countries in the Amazon basin. Widely distributed, the Yellow-warbler is also found throughout the islands of the Caribbean. A trepidation of these small bright yellow spring migrants can appear without notice as they hunt insects amongst the vivid green leaves of new growth at the edge of a thicket. The little songbirds nest from Mexico north into the northern third of the United States and most of Canada and Alaska. The bright yellow male has bold red-orange brown streaks on the breast sides, the female lacks or may have just a very slight hint of those streaks.
May 2, 2018 – A mostly yellow colored, female Summer Tanager was perched and focused on hunting insects, most likely a bee or wasp, at the edge of a wooded thicket recently in Iroquois county. The Summer Tanagers are neotropical migrants and have arrived in Northern Illinois for the nesting season from their wintering range in southern Mexico south to the the Northern half of South America. The male Summer Tanager, striking in color, is the only fully red bird in North America and is more easily noticed in the green canopy of the trees than the female.
May 4, 2018 – Of the nine species of orioles in North America, springtime brings us the rich songs and beautiful colors of two of those species. From the tree tops of our natural areas and throughout the neighborhoods and rural country homes with backyard feeders they suddenly arrive. The branches come alive with the black and bright yellow/orange Baltimore orioles along with the smallest oriole in North America, the black and chestnut colored Orchard oriole. Although less often seen with their darker colors they are no less beautiful. The two species nest in most of the eastern half of the United States. The Baltimore orioles’ nesting range also extends into the southern part of Canada. The Baltimore oriole spends the winter from Florida and the Caribbean south to Central America and the Northern most edge of South America. The little Orchard oriole spends its’ winter in southern Mexico and Central America. Keep your eyes and ears open for the sight and sounds of some our most spectacular visitors, the migrating spring orioles.
April 30, 2018 – We get a good look at those red eyes, orange bill and those unusually long feathers on the head as a pair of female Red-breasted Mergansers pause momentarily from their search for fish, frogs and crayfish. The Red-breasted Mergansers breed from Alaska south across Canada to the Great Lakes. The mergansers winter along the east coast from the Maritime Provinces south to Florida and along the Gulf Coast. On the west coast these diving ducks spend the winter from Alaska to northern Mexico. In the Midwest we see them every year, usually in small flocks during their migration.
April 19, 2018 – Good size flocks of Bonaparte’s gulls have been reported in Kankakee county and throughout Northern Illinois in recent weeks as they are working their way north to the boreal forests of western and central Canada and the southern half of Alaska where they will nest in the conifers. The small gulls prefer trees separated from the dense growth that are at the edges of marshes and bogs. A flock of 50 of these small and elegant tern like gulls was spotted in a flooded area of an agricultural field busily feeding on insects and worms, certainly to bulk up for their long journey north. The winter plumage of these gulls is mostly white, with a light gray on the tops of their wings and black wingtips, plus a dark spot on the sides of the head behind the eye. During the nesting season the adult birds’ head transitions to a slaty black as they get that wonderful dark hood that stands out in a beautiful contrast to their white body. This flock was made up of adult birds in full breeding plumage with some that were at different stages of transition, plus a number first year birds.
April 14, 2018 – Numbers of American White pelicans have been reported in our area for the past month. East of Momence near the Illinois/Indiana state line in Newton county Indiana, small and large flocks have been observed at the Black Oak Bayou of the LaSalle Fish & Wildlife Area. The pelicans are using the local small lakes, cooling lakes, and the backwaters of the Kankakee river as staging areas where they can rest and feed while waiting for that moment when that strong hormonal drive pushes them to head further north for the nesting season. Fifty of the large white birds have been counted at Black Oak with similar counts for J.C. Murphy lake at Willow Slough FWA. A flock of these great birds have been using a small rocky island in the Kankakee River State Park with a number of 25 birds reported on April 7th. Even larger numbers exceeding 100 have been reported near Braidwood and north to the Des Plains river.
April 5, 2018 – Most had their heads cocked with their faces tucked deep into their feathers as they perched sleeping side-by-side on this cold April morning in a springtime where winter was refusing to yield. Their long extended wing feathers, their primaries, appeared like little brown scabbards hanging from the belts of tiny soldiers that were dressed in their finest blue jackets. The weather was right for the snow that was predicted for later in the day and they seemed reluctant to leave their bivouac even well after sunup. There were more then 150 of these tired travelers roosting in a small tree at the edge of some flooded timber in the backwaters of the Kankakee river. Tree Swallows are known as short-distance migrators even though some travel as far as Alaska for the breeding season and nest in most of Canada and much of the United States. The Swallows winter along the South Eastern coast of the United States, the Gulf of Mexico and south into Central America. Some Tree Swallows have arrived even earlier and have been in our area for at least a month and they have already paired up and staked out their territory. This flock appears to be a recent arrival and may have traveled many miles in the last few days. They may still have some distance to go before they reach their destination, hopefully a more temperate weather pattern will soon take hold for this sleepy flock of traveling Tree Swallows.
March 28, 2018 – A pair of Horned Grebes glide silently across the placid waters of the Black Oak Bayou. One is still in its’ mostly achromatic winter plumage, while the other is transitioning towards the more impressive breeding colors of gold, black and chestnut. These small divers with their intriguing red eyes are on their northerly migration. The birds have been spending some time at a good food source of aquatic invertebrates and small fish at the Black Oak Bayou in the LaSalle Fish & Wildlife Area in Newton county Indiana. Soon the grebes will follow their instincts and continue the journey north into Canada towards the boreal lakes and marshes where their impressive courtship display will once again signify a bonding and the coming of a new generation of those red eyed divers.
January 19, 2018 – Snow Buntings are a small songbird of the high Arctic, a visitor that can be seen in our area with flocks of Horned Larks and Lapland Longspurs and sometimes in larger flocks of their own species. During the winter months here in Illinois they can be found feeding on dropped seeds along roadways or in the harvested agricultural fields. An interesting fact of these little birds, unlike other birds that can claim and alternate plumage, they only molt once and that is in the late summer. By the time spring rolls around and the Arctic breeding season is underway the browns and tan colored tips of their feathers are worn off showing mostly pure white with coal black wingtips. During their breeding season there are only a few slight differences in the plumage of the female and male.
