Although I saw my first American robin (Passeriformes: Turdidae: Turdus migratorius) of the season about three weeks ago, they really came out of the woodwork this past week. Now it seems like they’re everywhere, frequently in groups of a dozen or more, singing and foraging for earthworms.
Although robin populations shift south in the winter and north in the summer, throughout most of the United States these birds are actually present all year long. In the winter they seem to disappear because they spend most of their time roosting in trees. In the spring and summer they’re much more visible because they spend their time out in the open seeking mates, breeding, and gathering food for their young.
