While this image was taken last year at Horicon Marsh, I heard my first Killdeer sing 3 days ago in our backyard :) We have either seen or heard the following in the last week here in Wisconsin; Sandhill Cranes, Killdeer, Robin, Turkey Vultures, Red-winged Blackbirds & a few others.
Beautiful shot of this one. Haven't seen, or heard, any killdeer yet, but all the others have returned. Trumpeter swans are passing through, too. The geese and swans are making their usual spring raucous racket. Now if the snow and ice would all just melt!
