Raising A Baby Songbird

There is evidence to suggest that songbirds evolved 50 million years ago in the part of Gondwana that later became Australia, New Zealand, New Guinea and Antarctica, before spreading around the world.
Description
The song in this clade is essentially territorial in that it communicates the identity and whereabouts of an individual to other birds and also signals sexual intentions. It is not to be confused with bird calls which are used for alarms and contact and are especially important in birds that feed or migrate in flocks. While almost all living birds give calls of some sort, well-developed songs are only given by a few lineages outside the songbirds.
