Black Partridge

The black partridge, also known as the black wood partridge, is a small partridge, up to 27 cm long, with a thick bill, grey legs and a dark brown iris, and the only member of its genus. It is sexually dimorphic: the male has entirely glossy black plumage and a black bill, while the female is generally a chestnut-brown bird with a whitish throat and belly (Wikipedia, general species account).
