Calls and vocal behaviour of the Black Falcon Falco subniger
Some calls of the Black Falcon Falco subniger (adult female cackle calls and begging whines, adult male creaking call) are described and illustrated, together with quantification of calling rates of both sexes at four active nests near Tamworth, NSW. Females were more vocal than males at all stages...
