AbstractForaging vocalizations given by Japanese and rhesus momkeys reared by their biological mothers differed from each other in a single parameter. Calls made by a Japanese monkey fostered by a rhesus female were dissimilar to those of conspecifics reared by their biological mothers, but similar to those of rhesus monkeys reared by their biological mothers, and the vocalizations given by rhesus monkeys fostered by Japanese monkey mothers were dissimilar to those of conspecifics reared by their biological mothers, but similar to those of Japanese monkeys reared by their biological mothers. Playback experiments revealed that both Japanese and rhesus monkeys distinguished between the calls of Japanese monkeys reared by their biological mothers and of the cross-fostered rhesus monkeys on one hand, and the vocalizations of rhesus monkeys reared by their biological mothers and of the cross-fostered Japanese monkey on the other hand. Thus, production of species-specific vocalizations was learned by each species, and it was the learned species-difference which the monkeys themselves discriminated.
