White Wagtail (Motacilla alba)
Gannet (Morus bassanus)
Grey and white wagtail with prominent black markings on head and breast. British Isles subspecies M.a.yarreli (Pied Wagtail) with black back, and M.a.alba (continental) with grey back. Only faint black markings on head in juveniles and in winter plumage, but always shows big dark breast patch. Unmistakable in breeding plumage. Pale individuals of Yellow Wagtail and Citrine Wagtail, differs in lacking large breast patch, and in contact call.
Sound:Contact calls short and sharp. Usually with disyllabic, "bouncing" quality, and with each syllable only accented, not clearly separated from the other (see Grey Wagtail). Song either slow and primitive, consisting of sharp falling notes given by perched birds, or longer fast and energic bursts in excited song-flight.

CCWhite with black wing tips and yellow-buff at back of head. Juveniles brown with small pale speckles, white u-shaped rump patch and pale underparts. Fully coloured only after 5 years, and patchy, intermediate plumages often seen. Unmistakable bird at close range or with favorable light, but can be confused with shearwaters at a distance and/or in strong wind. Differs from those by long tail and much longer neck and head. Alternates between powerful, even and shallow wing-beats and glides. Flight becomes more shearwater-like in strong winds.
Sound:Heard mostly at breeding ground. Even, rhythmical series of harsh "harrr, harrr, harrr,".
