Purple Sandpiper (Calidris maritima)
Rook (Corvus frugilegus)
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.

An all shiny black crow with diagnostic bare, pale grey base of bill, and "baggy trousers". Juveniles lacks bare bill base and are difficult to separate from Carrion Crow. Young Rooks however, has a steeper forehead and more conical bill with less curved culmen. Tail is more rounded and base of wings more narrow. Flight action includes less gliding than Carrion Crow, and individuals are more spread when a flock flies.
Sound:Makes similar caws as Carrion Crow, but is harsher, softer, flatter with less rolling r's. Also gives a varied song of soft gurgling and rattling sounds, interwoven with calls at breeding ground.
