title: Does father know best? Social learning from kin and non-kin in juvenile ringdoves.
abstract: Parent-offspring transmission is usually thought to be the major route for cultural learning. We tested this assumption in ringdoves (Streptopelia risoria), a flock feeding Columbid that is easily raised in captivity. An aviary study first determined the foraging associations of juveniles placed with their sibling, their parents and a pair of non-kin adults. Juveniles foraged more often with kin than with non-kin and joined food discoveries in proportion to these foraging associations; aggression was relatively rare and came more often from unrelated adults than from parents. Two cage experiments showed that parents were not copied more often than unrelated adults when the two tutor types provided different, but equally productive, solutions to a feeding problem. Neither the ingestion of unfamiliar food (two seed types the juveniles had never encountered) nor the learning of a new food searching skill (opening a box containing seed) showed a differential effect of father versus non-kin tutors. Animals that scramble compete for food may thus acquire social information from whatever knowledgeable individuals are present, whether these are kin, unrelated conspecifics or heterospecifics.
