Abstract
The vocal displays of male Indian peafowl Pavo cristatus are thought to be sexually selected traits To clarify the specific call types involved in breeding as well as to provide basic information on the vocalisations of Indian peafowl we conducted monthly daytime recordings in a large feral population in Japan Based on 13420 records we identified seven different call types made only by males and six alarm calls uttered by both sexes Furthermore we found seasonal and diurnal changes in the calling activity of peafowl Three of the male call types keow ka and hootcall were particularly important for breeding as sexually mature males produced them only during the breeding season in a similar diurnal pattern to other breeding behaviours A digital video image relating to the article is available at http//wwwmomopcom/showdetailephpmovieid=momo061010ip01b
