Three-toed Woodpecker (Picoides tridactylus)
Black Guillemot (Cepphus grylle)
Shows no red patches in any plumages. Only woodpecker in WP with barred flanks. White stripes extends from behind eye to back and from base of bill to scapulars, but head is generally much darker than in other pied woodpeckers. Crown in male yellow, in female speckled white.
Sound:Drumming powerful and slow, with each beat clearly distinguishable. Most similar to Black Woodpecker but not as long (1 - 1.4 seconds). Accelerated ending (just the last few beats). Contact call similar to Great Spotted, but deeper and softer. Not very vocal.

Unmistakable in summer with almost all black plumage. White oval wing-patches in all plumages. Only auk with white wing-panels. Bill quite slender and pointed, body and wings rounded. Winter plumage blotched in grey and white, with dark wings (with white coverts). Typically scans for food by frequently dipping forehead in the water.
Sound:Call surprisingly high pitched. Quite pure, drawn out, plaintive whistling notes in same pitch range as Hazel Grouse.
