If you think about it, the American Robin epitomizes what most North Americans think of when they consider song birds, nesting birds, and especially bird eggs. Three states (CT, MI, WI) have it as their state bird. It is one popular bird!
I love watching them strut the ground feeling the vibrations of subterranean worms. They cock their heads as if listening or looking with one eye for worms. What is that all about anyway?
