|Brown Thrasher sightings in the past 30 days|
Today saw incredible numbers of birds--including arrivals and influxes--intercepted by birders using this almost perfect Saturday. I say almost, because migration was actually cut off in southerly Illinois by a line of storms, which ultimately created a wall between Illinois and migrants further south. Nonetheless, migrants used the predominantly southerly winds to their advantage en masse last night, with species like BROWN THRASHER, EASTERN TOWHEE, AMERICAN BITTERNS, and YELLOW-RUMPED WARBLERS becoming some of the most common species even in Northern IL. Elsewhere, new warblers, shorebirds, raptors, and influxes of these groups continued to fill in today, making it truly a day to be reckoned so far as this late spring goes. And having participated in a Big Day in Lake County today, it was more than exciting to be out there from the pre-dawn hours to sunset. Expect a report of this soon. It may be rather exciting as well ;).
Tonight's a bit iffy for migration (see the image to the right to see why). That counterclockwise spinning sphere of wind just east of Illinois is a small but powerful low-pressure system. Seeing as it is

Awesome work today, Illinois! Keep on keeping' on.
