Common Tern (Sterna hirundo)
Hazel Grouse (Tetrastes bonasia)
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.

CCEasily overlooked, secretive grouse. Small and compact, with small head and rounded body. Upper parts grey, wings speckled in brown. Tail grey with broad black terminal band. Male with short crest, contrasting black throat patch and generally brighter coloured than female.
Sound:Song an extremely high pitched whistle; "piuuuuuuuiiii pju pju pju". Start-note typically sustained, first descending then ascending and descending again. Often followed by three short conclusive "pju, pju pju". Warning call of female a bubbling thrill.
