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.
