The function of displays in the breeding of the White-tailed Black Cockatoo

Abstract

The displays of the White-tailed Black Cockatoo Calyptorhynchus baudinii latirostris during the breeding season are described. The few obvious displays are associated with agonistic situations, copulations and allopreening, although the pair are together for less than an hour most days once breeding has started. The lack of spectacular displays after incubating begins possibly reflects the strength and permanence of the pair-bond.
