  • Without genetic tests of parentage, descriptions of mating systems must be considered hypothetical. Here we confirm the existence of cooperative polyandry in the Galapagos hawk (Buteo galapagoensis) using multilocus minisatellite DNA fingerprinting. In this species, breeding groups consist of one adult female and from one to eight males (the modal number of males is two). In polyandrous groups, all males copulate with the female and participate in the provisioning of the young. DNA samples from… CONTINUE READING
