Appearance:

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.

Appearance:

Differs from Arctic Tern in longer head, and more orangy red, rather than deep red, bill. Tip of bill usually black. Legs longer, but tail streamers shorter than AT. Underparts of primaries with diffusely bordered dark trailing edge (sharply bordered in Arctic Tern). Upper side of primaries with dark wedge (less apparent in winter). Secondaries opaque. Crest more apparent than in Arctic Tern and underside whiter. Juveniles with buff back.

Sound:

Similar to Arctic Tern but deeper. Lacks latter's high pitched "tip-tip-tip" call, and the drawn out "kree-aaahh" call falls more distinctly in pitch.
