Dunnock (Prunella modularis)
Common Tern (Sterna hirundo)
Sparrow-sized, brown and streaked passerine with slate-grey head and chest. Bill thin and warbler-like, head rounded. Narrow, pale wing-bars. Often forages on ground in a crouched manner, creeping or hopping with legs almost hidden. Flicks wings and tail when restless. Secretive behaviour, except when visiting feeders and when singing from tree tops.
Sound:Contact call a dry, thick trill "trrr", and a short King Fisher-like, high-pitched "zeep". Song a fast and evenly paced, high pitched stream of clear notes. No consistent phrasing. Similar in timbre to Robin, but does not vary tempo or pitch nearly as much. Often compared to the sound of a squeaky wheelbarrow.

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.
