Sure as shooting it's Spring in Pennsylvania. Early Spring, but Spring nonetheless!
Yesterday I had a pair of Hairy Woodpeckers courtship displaying outside my window at work, and a Fox Sparrow under the feeders, and a Chipping Sparrow showed up. Flocks of Common Grackles are on the move, and all the cavity nesting birds are singing away. Fish Crows are moving back into the neighborhood. We may yet get a late snowstorm, but we've turned the corner. Spring is in the air!
