Two-barred Crossbill (Loxia leucoptera)
Common Tern (Sterna hirundo)
Plumage like other crossbills; male red, female and juveniles green. Both sexes and all ages with two broad, white wing-bars, which distinguishes it from congeners. Nonetheless, the species is easily overlooked when in mixed flocks with other crossbills. Build slightly more slender and long-tailed than other crossbills. Often discovered through its contact call.
Sound:Contact call a "chep chep" similar to crossbill but softer, interspersed with characteristic, toy-trumpet call with redpoll-like timbre, but with a more flat intonation. Song more like redpoll than a crossbill, with rattling and chittering notes.

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.
