Appearance:

Slightly smaller and less heavy than Willow Ptarmigan. Overall greyer plumage, and a more delicate bill. Male summer with grey upperparts and white underparts. Female summer with browner upperparts than male. Both sexes completely white in winter plumage, except for black lores in males. Wings white and tail feathers black in all plumages in both sexes.

Sound:

Call of male a very distinct "rrrrrrr", being a rattling rapid pulse of clicks, like running a stick along a picket fence. Female has similar sounds, but is higher pitched and not so coarse as male.

Appearance:

Differs from Baillon's Crake in long primary projection in all plumages. At least 5 tips of primaries visible behind tertials. Adult birds show red base of bill, but this is sometimes difficult to see and immature may lack this altogether. Male with lead grey underparts, female with grey face and buff underparts. Immature with barred and spotted underparts but less so than immature Baillon's. The crown is also more evenly dark together with dark ear coverts. The species appears slimmer than Baillon's Crake due to longer neck, tail and legs.

Sound:

Rich repertoire of calls used freely in breeding season. Male song diagnostic. A loud series of short, nasal ascending "quek" repeated every one and a half seconds or so, before accelerating and descending at the same time to a more guttural voice. Female song with similar short "quek" but with less pure tone and in shorter series (sometimes just one call), immediately followed by a rolling trill.
