How cooperatively breeding birds identify relatives and avoid incest: New insights into dispersal and kin recognition.

Abstract

Cooperative breeding in birds typically occurs when offspring - usually males - delay dispersal from their natal group, remaining with the family to help rear younger kin. Sex-biased dispersal is thought to have evolved in order to reduce the risk of inbreeding, resulting in low relatedness between mates and the loss of indirect fitness benefits for the… (More)
