Index of Subjects --Apple-Mail-174--591907812 Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes Content-Transfer-Encoding: 7bit Hi Andy, Birds give voice to a variety of vocalizations some of which (alarm calls, contact calls, etc.) are given by females as well as males. What we often consider "singing" is a part of territorial display (to define nesting and foraging territories), something which is normally done by males. Having said that there are birds such as cranes that have very involved unison-calling displays, which are part and parcel of pair bonding, and in these the females "sing" as well, frequently having a different "part" than the males. Other birds such as storm petrels have songs that returning and incubating partners sing to one another in burrows in which the females also participate. I suspect that there are many examples that don't immediately come to mind.
