According to Ken Brock's Birds of Indiana, today (April 6) is the departure date for Dark-eyed Juncos for the southern tier of Indiana. If I'm interpreting Brock correctly, this means that 90% of the juncos around here should have moved on by now.
This date triggers my annual Junco Countdown, where I start to track juncos day-by-day to see when they finally disappear entirely.
Today there are still juncos under the feeders whenever I happen to look out, but the numbers are lower than they were even a week ago.
P.S. As a point of reference, the junco departure date for the central tier of Indiana is April 11, and it's April 20 for the northern part of the state.
