Deb and I took a bike ride along the Platte yesterday, and encountered plenty of activity and signs of Spring:
Tree Swallows are back
Say's Phoebe heard
American Wigeon, Green-winged Teal, many Bufflehead pairs, Common and Hooded Mergansers, Ring-necked Duck, an apparent early Blue-gray Gnatcatcher, Song Sparrows, and some very animated courtship/territorial battling between 3 Killdeer.
