Gannet (Morus bassanus)
Montagu's Harrier (Circus pygargus)
White 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,".

Elegant harrier, with slender wings and 4 "fingers". Adult male easily recognized by single black band on upperwing, and double on underwing, and by rufous under wing-coverts. Chest is considerably darker grey than in Pallid Harrier, in contrast to white lower belly. Adult female differs from Hen- and Pallid Harrier by dark upper wing-band (not as prominent as in male). Broad, pale subterminal band on underwing reaching all the way to wing pit. Under wing coverts barred. Immature birds told from Hen Harrier by rufous, almost unstreaked underparts. From Pallid Harrier by dark wing tips and no marked, dark neck sides or pale collar. Beware of moulting Hen Harriers, with 4 "fingers".
Sound:Quite similar to Hen Harrier. Seldom heard, even at breeding ground. Sharp "ke-ke-ke-ke", and various high-pitched whistling sounds.
