Chestnut-quilled Rock Pigeon

The chestnut-quilled rock pigeon is a dark sooty brown pigeon with a distinctive bright chestnut patch on its wing visible in flight. It has distinctive pale lines across its face curving above and below its eye. A species of bird in the family Columbidae, it is very similar in behaviour and habitat to the white-quilled rock pigeon but it is only found on rocky escarpments in western Arnhem Land in the Northern Territory of Australia.
