The collared crow, also called the ring-necked or white-collared crow (Corvus torquatus), is a crow native to China and the north of Vietnam. It is 52–55 cm long, the same size or slightly larger than the carrion crow, with proportionately slightly longer wings, tail and bill. The plumage is glossy black except for the back of the neck, the upper back and a broad band around the lower breast, which are white. (Wikipedia, general species account)
It sometimes flies with its feet hanging below the body in a characteristically lazy way. The voice is a loud kaaar repeated several times, and during its head-bowing display it utters strange clipping and clicking sounds. (Wikipedia, general species account)
