Genetic evidence for cooperative polyandry in reverse dichromatic Eclectus parrots

Heinsohn, Robert; Ebert, Daniel; Legge, Sarah; Peakall, Rodney

Description

Group size in cooperatively polyandrous birds appears to be limited by the diminishing probability that any one male will achieve paternity as group size increases. Here we use molecular techniques to analyse the mating system of Eclectus parrots, a species with a surprisingly large number of males (up to seven) in each group. We show that their social groups are not composed of kin, and that all males seek direct fitness. Most broods of two nestlings had just one father. However, further group...[Show more]
