Long Songbirds 3
The findings go beyond modern species. After carefully tracing back an evolutionary family tree for their songbirds, Garamszegi's team discovered that, in at least two bird families, singing evolved in females first. They suggest these ancient females may have been using their songs to deter other females from their territories, to coordinate breeding activities with males, or possibly to attract mates.
