Wonga Pigeon
Leucosarcia melanoleuca
The wonga pigeon is a large, plump pigeon that has a short neck, broad wings, and a long tail. Its length varies from 38 to 40 centimetres (15.2 to 16 inches). It has pastel blue-grey back feathers. The head fades to a creamy-white colour. The underside is white with dotted dark grey spots such that a white V can be seen on its chest. Their eyes are a dark red-brown colour and they have pink eye-rings that encircle them. Legs are red and the sexes appear identical but immature pigeons are browner with a less distinct V pattern. Voice: The call of the wonga pigeon is a loud, high-pitched 'coo' repeated over long periods of time for a number of seconds. When males are displaying mating, bowing occurs with a soft, trilling coo.
