Why Do Birds Sing?
Birds sing as a way of communicating with one another. A male bird may sing to attract a mate or he may sing to warn other birds of his kind to stay away from his nesting territory.
Scientists call this the dawn chorus. It can start as early as 4:00 a.m. and last several hours. Birds can sing at any time of day, but during the dawn chorus their songs are often louder, livelier, and more frequent.
Sometimes they seem to sing just for the joy of it. Each kind of singing bird has its own special song. Not all birds sing, but nearly all give calls. Some birds have calls they use to announce that they have discovered food.
Many birds use danger calls to warn other birds that an enemy is nearby. Birds “talk” to their babies with calls, and baby birds use calls to say they are hungry.
