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.

Appearance:

Small martin with dark brown chest-band and white throat. Upperparts dark brown, underparts white. Underside of wings dark. Juveniles with light fringes to brown feathers, and buff throat. Flight more elegant than Barn Swallow and House Martin. Often changes direction but keeps altitude. More fluttering flight than House Martin, with less gliding.

Sound:

Contact call a mono- or disyllabic "trrrrt". Similar to House Martin but more raucous and less crisp, with less rolling r's, and with stable pitch throughout. Song a primitive improvisation on the contact call. Alarm call similar to House Martin; a sharp plaintive "tseep", but somewhat purer and more drawn.
