Buzzwords in females' ears? The use of buzz songs in the communication of nightingales (Luscinia megarhynchos).

Differences in individual male birds' singing may serve as honest indicators of male quality in male-male competition and female mate choice. This has been shown e.g. for overall song output and repertoire size in many bird species. More recently, differences in structural song characteristics...
