In many passerine species males have enlarged cloacal protuberances during the breeding season. One hypothesis for the evolution of cloacal protuberances posits that they are a response to sperm competition and thus predicts that both within and between species the size of the protuberance correlates with the number of sperm stored. Here we provide the first intraspecific test of this hypothesis. In Australian fairy-wrens (Aves: Maluridae) females regularly mate outside of their social group… CONTINUE READING
