Black-billed Capercaillie

The male black-billed capercaillie averages 89–97 centimetres long and weighs 3.4–4.6 kilograms, with females around 69–75 centimetres and 1.7–2.2 kilograms; the wingspan is about 75–115 centimetres. Compared with the western capercaillie it is slightly smaller, with a slimmer body and longer neck, a black beak instead of a horn-coloured one, and a longer, more spatulate tail. The eastern capercaillie has a somewhat glossy bluish-black head and neck down to a metallic turquoise breast. (Wikipedia, general species account)

A large grouse closely related to the more widespread western capercaillie, it is sedentary and breeds in the larch taiga forests of eastern Siberia and parts of northern Mongolia and China. In the far west of its range it has been known to hybridise with the western capercaillie. The larch forests it lives in are usually less dense than other taiga, so it is more adaptable to open habitat and tends to avoid thick coniferous forest. (Wikipedia, general species account)
