I thought the saying was "The Early Bird Catches the Worm" but maybe it is "The Early Bird Catches the Slush". After a brief visit, Spring decided it wasn't ready to commit full-time to Chicago yet so winter is back (slush is falling from the sky, it's in the 30s).
But the mid-week Spring conditions did get the birds moving around a bit. Here is a pictorial summary of bird sightings this past week.
