Quick facts Songbirds Temporal range: early Eocene to present, Scientific classification ...

There are about 4000 species of songbird. Their syrinx (vocal organ) is able to produce varied and beautiful singing.[1] They are a very successful group of birds, in fact they are the dominant birds on Earth today.

It seems songbirds evolved 50 million years ago in the part of Gondwana which later became Australia, New Zealand, New Guinea and Antarctica. They then spread around the world.[2][3]

Song

Their song is mainly territorial: it communicates the identity and whereabouts of an individual to other birds of the same species. It also signals sexual intentions. Female preference in some populations is based on the extent of a male's song repertoire. The larger a male's repertoire, the more females a male individual attracts.[4]

Bird calls are also used for alarms and contact. They are especially important in birds that feed or migrate in flocks. Although almost all birds give calls of some sort, well-developed songs are only given by a few lines outside the songbirds.
