Summary

A captive pair of pied barbets (Tricholaema l. leucomelan) regularly performed false copulations with the same repetition rate per bout and the identical accompanying duet as is typical of true copulations, the only difference being that cloacal contact did not occur. 10 months after its first brood, the pair was again allowed to excavate a nest-hole and breed. After 2 to 7 days of excavation, false copulations were replaced by functional ones. From incubation through fledging of young neither type of copulation occurred. Two causal explanations accounting equally well for false copulations are suggested.
