Activity 1: Definitely a Robin has a different size shape from a Blue Jay.
Activity 2: I saw three different woodpeckers at my feeder-the red headed woodpecker, the red bellied woodpecker and the downy woodpecker. And I thought a woodpecker was a woodpecker!
Activity 3: Most of the birds I am watching--cardinals, finches, sparrows, blue jays, woodpeckers, wrens and thrashers-- are eating from my feeder--eating me out of house and home! But robins definitely like the worms in the yard and the little humming bird is enjoying my hummingbird feeder.
Activity 4: I think my favorite bird is the robin because I had the opportunity to watch the couple build their next on our gutter downspouts, take turns caring for their nest and feeding their babies--they definitely were a team! Unfortunately something got to the nest before the babies could fly. :-( But I've learned they will rebuild their nests and try again! My second favorite is the cardinal because it is so beautiful--red is my favorite color--and they have a nice sound.
