CAPTION:
"MANY BIRDS communicate by making sounds, but only songbirds produce complex, musical songs. They use their songs to claim breeding territories and to attract mates. Songbirds belong to a group called perching birds. These birds have feet with three toes pointing forward and one pointing backward."
"RED-CRESTED CARDINAL
This South American bird is usually seen in pairs or small groups, feeding on a variety of seeds on the ground."
"BLUE BIRD OF PARADAISE
This songbird hangs upside down and fans out its feathers to attract a mate."
