Sandwich Tern (Thalasseus sandvicensis)
Lapland Longspur (Calcarius lapponicus)
Large tern with black bill, with yellow tip (adults). Bill all black in juveniles. Long black cap and shaggy crest. Generally leaves a much whiter impression than other terns in the region (except Roseate Tern). Adult summer: Yellow bill-tip. Tail pure white, and upperparts pale grey. Outer primaries darker than rest of wing, and contrast increases in worn plumage. Broad white trailing edge to inner wing. Underside of primaries with faint narrow dark trailing edge. Forehead white in adult winter and first winter plumage. Juveniles: scaly upperparts and dark bill. Less evenly coloured than juvenile Gull-billed Tern. First winter birds similar to juveniles, but back purer grey and bill shorter. Can be mistaken for Gull-billed Tern, but note different profile. Flight powerful with evenly narrow wings and a front-heavy appearance, due to the long head and bill. Often dives from high above the surface and stays under water longer than Common and Arctic T.
Sound:Contact call a sharp and grating "keeree-eek". Often compared to the pressing of amalgam into a tooth.

CCLarge and rather heavy bunting with yellow bill in all plumages. Head of breeding male brightly tricoloured in black, white and warm, rufous brown. Female similar to male, but much duller coloured, and with black parts speckled. All adults show rufous hind-neck. Juveniles show rufous greater coverts and may be confused with Reed Bunting. Differs from RB in yellow bill, dark spots on chest and cleaner markings on cheeks. Often runs along the ground like a mouse.
Sound:Song: a short, creaky, brittle phrase, rich in harmonics; "kril-trrlrtt-ti-trlllkrlltrrt". Somewhat reminiscent of Horned Lark, but without its hesitating intro. In form a bit like Snow Bunting, but much less clear tones. Call: A Snow Bunting-like "prrrrit", but tone harder. Also a Snow Bunting-like "pjuu". Other sounds: soft, whistling calls reminiscent of Bullfinch, but with richer harmonics.
