White Wagtail (Motacilla alba)
Pallid Harrier (Circus macrourus)
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.

CCSlender and elegant harrier, with narrow wings and four "fingers". Adult male easily recognized by very pale grey and white plumage, with diagnostic wedge-shaped, black wing-tips (outermost primary grey). Female and immature birds often difficult to tell from Montagu's Harrier and Hen Harrier. Adult female differs from Montagu's by lack of dark band on upper wing, and by diffuse, sooty inner underwing. Pale bands do not reach wingpit, and under coverts are darker. Differs from female Hen Harrier by noticeably slimmer wings (both hand and arm) and only 4 fingers (but beware moulting Hen Harriers). Immature similar to Montagu's with unstreaked, rufous underparts. Differs in pale tips of inner primaries, and dark half-collar and pale "boa".
Sound:Some calls similar to Montagu's and Hen Harrier, but display call quite diagnostic. A thin, vibrating trill "peerrrrrrrr".
