Sterna bergii

Movement patterns mostly unknown, and many populations more or less resident around breeding areas. Australian birds disperse several hundred kilometres around colony. Race velox disperses mainly within its breeding range, but Biddle East birds move S to E African coast after breeding, and winter mainly from Egypt to Kenya, overlapping with thalassinus. Non-breeding birds of nominate race overlap with enigma.
