Peregrine Falcon (Falco peregrinus)
Pallid Harrier (Circus macrourus)
Large and athletic falcon. Adults slate-grey above. Underparts white with black barring. Head almost black. Juveniles with brown tone to plumage, coarse longitudinal streaking below and paler head. Differs from the smaller falcons by less pointed wings, heavier hips and short tail. Highly contrasting and broad moustache-stripe. Smaller than Gyrfalcon with a more compact silhouette. The wings are not as broad, and belly not as deep. Underside of wings evenly barred, without contrasting coverts. Flight-pattern can recall Fulmar, with shallow, stiff wing-action.
Sound:A harsh, drawn out "kiaaaa" with emphasised endings repeated in series. Much slower than Merlin, but higher pitched than Gyrfalcon. Also shorter, coarse warning-calls.

Slender 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".
