Sandwich Tern (Thalasseus sandvicensis)
Red-necked Phalarope (Phalaropus lobatus)
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.

CCCan only be confused with other phalaropes, due to swimming behaviour. Juveniles and winter plumage birds can be mistaken for Red Phalarope, but bill is much more needle-like and neck and body more slender. Juvenile birds with prominent buff stripes on back, and first winter birds with dark fore-crown (see Red Phalarope). Adult winter with white stripes on back, as opposed to Red Phalarope's uniformly grey back.
Sound:Short and sharp "teck", sometimes repeated to form trilling series. Also a mewing, nasal "veeoo".
