Collared Dove (Streptopelia decaocto)
Common Tern (Sterna hirundo)
A small, long-winged and pale buff-grey pigeon, with characteristic black half-collar stretching from the hind-neck to the sides. Most likely to be confused with Turtle Dove, but upperparts of tail lacks strong contrasts, undersides of wings are whitish and lower belly buff (not white). Juveniles lacks the black neck-collar.
Sound:Song a characteristic, rhythmic cooing, consisting of three syllables with emphasis on the second. The third lower pitched than the rest. Can be rendered as "su-do-ku" (or "deca-oc-to", latin name derived from song). Excitement-call a nasal "wrrraa".

CCDiffers 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.
