I always know when spring is here as the common grackles and cowbirds descend upon my feeders in droves. I have also noticed that the males are singing more and that the sparrows have taken over my bird houses and have quite elaborate nests already made. Although I am moving bird houses around, so he is going to be sadly disappointed.
The finches have begun to change colors from the drab olive gray color of their weinter plumage to the canary yellow color of their summer plumage. Right now they are just mottled up looking.
