Appearance:

Large, stocky Calidris. Easily identified when direct size-comparison with congeners possible. Elongated body shape and short legs. Bill robust, short and straight. Summer plumage: Upperparts speckled in brown and grey, underparts warm rufous brown, like Curlew Sandpiper. Legs dark. Winter- and juvenile plumage: Pale grey upperparts (scaly pattern in juveniles), and white belly. Legs greenish in both juveniles and winter-plumaged adults. Note pale grey rump and uniformly grey tail in flight. Wing-bars less prominent than in Sanderling.

CC-sounds:Stein Ø. Nilsen, XC317787. Accessible at www.xeno-canto.org/317787.

Appearance:

Bulky raptor with long tail and short, rounded wings. Small males may be difficult to separate from large Sparrowhawk females. Upperparts grey-brown, and underparts pale and barred or speckled. Male and female quite similar, but female larger. Juveniles browner than adults, with heavily speckled underparts. Supercilium prominent in both sexes. Bulkier belly and broader at base of tail than Sparrowhawk. Deep chest. Longer wings and longer secondaries gives more of a S-shape to trailing edge of wings. Slightly rounded tail-corners visible when soaring. Flight alternates series of wingbeats with short glides without loosing height.

Sound:

Series of short "ke-ke-ke-ke-ke". More resonant, both sharper and deeper pitched than similar call of Sparrowhawk, and much slower. Also a wailing "peeeaaaaw"
