Common Loon and One-week Old Chick
The Common Loon is the Minnesota state bird. It has a black bill, red eyes and a spotty black and white body with a black/iridescent green head. The common loon has four calls. The tremolo, which sounds like maniacal laughter, is an aggressive call. The wail is a long, drawn-out sound that people mistake for a wolf. The hoot, a shorter call, is used to communicate among parents and young. Male loons make a yodel sound when guarding their territory. Loons can dive as deep as 250 feet to search for food.
