Development of song and reinforcing effects of song in female chaffinches.
Eight autumn-caught female chaffinches were injected with testosterone in their first spring. They were allowed to perch on a particular perch to produce a playback of a normal, male song. Both the course of their song development and the reinforcing effect of the playback song were comparable to that shown by a group of similarly-treated males.
