Description
The appearance of the male black-billed capercaillie is similar to that of its western counterpart, except that it is slightly smaller, has a smaller bill, and a slightly longer tail. The black-billed is also more predominantly black, and there are large white spots at the tips of the uppertail coverts and on wings. The appearance of the female is similar to that of its western counterpart, except that it is greyer with more uniformly scaled underparts, lacks a rusty unmarked breast area, and has more noticeable white spots on wings. Their call is a crackling noise. In the far west of its range the black-billed capercaillie has been known to hybridise with the western capercaillie.
