Purple Sandpiper (Calidris maritima)
Long-tailed Jaeger (Stercorarius longicaudus)
Robust, compact and dark wader, with relatively long and slightly curved bill. Mostly seen in winter at the coast where it prefers rocky surfaces as opposed to most other waders. In winter plumage the base of bill and legs are yellow, and the upperparts grey with dark markings. Breeds in high Arctic and mountains. Summer plumage darker than winter, with brown fringes/spots on back, and darker bill and legs. Similar wing and rump pattern to Dunlin, but appears overall darker. Tail extends beyond wing tips of resting birds. Flight patterns at wintering grounds straight and low.
Sound:Contact call a hoarse and hard "weet". Sometimes in chattering series. Song quite varied with series of short, nasal, vibrating sounds, interspersed with drawn out, slower calls.

Breeding plumaged adults with streamers unmistakable (streamers comprising two thirds of total tail length). Adult plumage shows less variation than in other skuas. No hint of breast band, and transition between pale belly and darker vent very diffuse. No white patches at base of primaries of underwing in adults. Juveniles easily confused with juvenile Arctic Skua, but are more slender. Wings narrower and primaries and tail longer. Juvenile Arctic Skua shows white patches at base of primaries on both sides of wings, juvenile Long-tailed only on underwing, and on first few primaries of upper. Barred rump and tail coverts in juveniles. Flight elegant and buoyant.
Sound:Calls sharp and less full-bodied than Arctic Skua, and not so mewing. Short, double-accented "kew-wev" or short "kerk" in agitation. Also a long drawn-out "keeeeaah", resembling both Arctic Skua and Common Gull.
