Curlew Sandpiper (Calidris ferruginea)
Rook (Corvus frugilegus)
Summer plumage: Warm, rufous brown below like Knot, but much smaller. Bill curved and much longer, and appearance more long-legged. Winter and juvenile plumage grey above and pale below. Differs from Dunlin in slightly longer legs and bill, more pronounced supercilium, no black patches on belly (some rufous summer feathers may show when moulting) and more upright stance. Juveniles with buff-pinkish tone to breast, and scaly upperparts. Always distinct in all plumages when flying, due to bright white and crescent-shaped rump-patch.
Sound:Flight call a soft, ringing and rolling "krrrrrt, with variations. Lacks the hoarse, nasal quality of similar call by Dunlin.

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.
