Corn Crake (Crex crex)
Black Guillemot (Cepphus grylle)
About half the size of Partridge with brownish plumage, bluish grey supercilium and breast sides. Flanks barred in white, back heavily streaked. Rufous wings obvious in flight. Seldom seen due to secretive behaviour, but song very noticeable.
Sound:Characteristic song can be heard at night. A rasping, hoarse "crex-crex" repeated about every second for long periods of time.

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.
