I live on the outskirts of Wrigleyville in Chicago, about a mile from Montrose Point and its famous bird sanctuary. My third-floor apartment offers a decent and relatively unobstructed view to the west. When I’m home I often look out my windows to see if anything is flying by. I’ve had some interesting birds and birding experiences over the years – Bald Eagles and Peregrine Falcons, big flights of Common Nighthawks in late summer, and when the conditions are right, flocks of Sandhill Cranes in late fall. On the morning of October 28, 11 Sandhills came in from the north, not far from my apartment building. Sandhill Cranes are less common close to Lake Michigan – I rarely get large flights of them, unless the wind is strong and from the west, which it was on October 28. When those conditions occur, and I have time to look, I sometimes see hundreds or even thousands moving south. I didn’t have a lot of time that day, so those 11 Sandhills were all I saw.
If you live in Chicago and want to see Sandhill Cranes, check the skies from late October to early December on days with strong west winds following the passage of a cold front. You might see them under other weather conditions but they move en masse on days with west winds, the stronger the better.
