Hoopoe (Upupa epops)
Black Guillemot (Cepphus grylle)
Always unmistakable. Distinct, foldable, fan-like crest. Rounded, rectangular wings and long curved bill. Buff body, black wings and tail with conspicuous white barring. Catches the eye when flying by in undulating, butterfly-like motion.
Sound:Song a characteristic, hollow, far-reaching and trisyllabic "hoop-hoop-hoop". Dove-like timbre and slightly ascending in pitch. Sometimes two or four syllables, depending on virility of male. Other calls include a dry, hoarse and rasping "ehrrrrrr".

CCUnmistakable 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.
