January 14, 2021 – Common mergansers, Golden-eye ducks, and Greater white-fronted geese have all been spotted from our river parks here in Kankakee County this past week. Four Greater white-fronted geese swam up river at Cobb park past a large number of Canada geese and a few Mallard ducks that were gathered along the north bank. The nervous white-fronted geese, also known as the “specklebelly”, were spooked by runners as they jogged through the park. The geese flew upstream making their strange high pitched laughing sounds as they went out of sight. An adult Bald eagle could be seen perched high in a tall tree down river from Jeffers park watching for a meal opportunity on the ice free waters of the Kankakee. A Merlin falcon was at the rivers’ edge at Jeffers park in the shallows bathing in the cold water. The little falcon soon flew up into a tree, the same tree where a Belted kingfisher was watching for small fish from a good perch that stretched out above the water. The Merlin perched on a cold looking icy branch after its chilled bath. The little falcon spread its tail feathers wide, drying them in the frigid January air for a good fifteen minutes before heading a short distance west to another tree. Down river at the Kankakee River State Park on the west end of Langham island four beautiful Tundra swans, two adults and two juveniles, were spending the morning among a number of Canada geese. The white swans stuck out like a sore thumb among the dark colored smaller Canada geese. The Tundra swans are here through the winter months taking up temporary residence on the open waters of lakes and rivers in the lower 48. These swans are probably part of the eastern population and are a long way from their summer nesting range on the northern coastal areas of Alaska east along Canada’s Arctic coast to Hudson Bay and north up into the Canadian Arctic Archipelago. The dynamic winter weather of the Midwest can bring wintering birds to any open water as rivers and lakes freeze during cold periods. Those weeks of cold temperatures can be an exciting time for nature lovers and bird watchers, concentrating many species of waterfowl and birds-of-prey to those shrinking areas of ice free water.
January 23, 2010 – The Merlin falcon is a small but fierce hunter that is a little larger and heavier than the American kestrel. Looking somewhat like a chunky pigeon in flight the Merlin was once known as the pigeon hawk. The stealthy falcon lacks the bold color patterns and black “mustache” that adorns the face of the more common Kestrel. The Merlin’s may show a faint “mustache”, the black plumage on the sides of the face, but the bird appears a bit drab overall compared to the smaller and more colorful Kestrel. The female Merlin, like other birds of prey, is larger than the male. A large female with a recent catch of a small bird was facing away from me as it sat on a roadway in Iroquois county a few years back. From a distance the bird looked like a small Peregrine falcon, its’ solid blue-gray back and wings stood out and its’ thick body confused me at first until the bird took to the air with its’ prey. At that point I recognized it as a Merlin. The little Merlin is an avian hunting master that can send a flock of birds into a mass of fear and confusion. Outmaneuvering the unfortunate winged victims like Starlings, Sparrows and even small ducks, the Merlin,with a swift and precise attack snags its’ targeted prey while in flight. It also plucks dragonflies and other insects out of midair during its’ migration for a quick and easy snack. If you are fortunate enough to see a Merlin in our area of Northeastern Illinois it will most likely be during the winter months but sightings of the Merlin are becoming more common as the population of the little falcon has improved. The Merlin is known to breed in the boreal forests of the north but the discovery of a hatchling on the ground in Northwestern Cook county in 2016 may signify that they are expanding their breeding range.
March 20, 2019 – The little falcon was perched and alert with its’ senses focused on a few thousand loud clattering mostly male Red-winged blackbirds that were on their spring migration. There was such an impressive number of birds in this flock that they gave the late winter trees and shrubs an appearance of being covered in dark leaves. Patiently watching from an old snag, the Merlin concentrated on a part of the flock that were flying, resting, and feeding in the grasses and along the roadway just to the north. Soon the little raptor, with a sudden and great speed, left its’ vantage causing the flock to take to the air in a large cloud of an evasive synchronization that resembled that well known and mesmerizing murmuration of starlings. I quickly lost sight of the little falcon, but I suspect after all of that commotion, which lasted no longer than 30 seconds, there may be one less blackbird in that huge flock of travelers.
The Merlin falcon is a compact and powerful bird of prey, it is slightly larger then the American Kestrel, which is the smallest falcon in North America. The Kestrel is a common falcon in our area that can be observed year-round, often perched on a utility wire while it is hunting voles, mice and insects in the grassy ditches and waterways along our rural roads. The less common to our area is the Merlin, it is often recorded in Illinois during the winter months. It spends the summer, during the breeding season, in the boreal forests of Canada. It appears though, that the Merlin is expanding its’ summer range. In recent years there has been an increase in nesting records in Wisconsin that seems to be expanding south, according an article by Eric Walters “Merlins Nesting In Illinois” published in a journal of the Illinois Ornithological Society. Data collected daily from bird enthusiasts is reflected in the eBird range maps for this species and shows that there has been a number of recorded Merlin sightings in June and July in Illinois along with a few confirmed nesting records in Northern Illinois and Northern Indiana in recent years.
