The wailing call and the creaking call of the Peregrine Falcon Falco peregrinus were quantified throughout the breeding period. The creaking call was given mainly during the courtship period by both males and females, and its frequency at this time did not differ significantly between sexes. From the start of incubation and thereafter, the creaking call was uttered more frequently by males than by females; during the nestling period, it was mostly related to the male's transfer of food. The wailing call frequency never differed significantly between males and females and increased during the nestling period. This call was less linked with the presence of the mate than was the creaking call.
