Appearance:

A large buzzard with variable plumage. Typical traits are: White, almost translucent base of primaries in contrast to black tips, defined black trailing edge to flight-feathers, almost unbarred rufous tail, pale head, dark "trousers", dark carpal patches and rufous under wing-coverts. Due to long wings, the flight profile is most similar to Rough-legged Buzzard, and a combination of structural and plumage characters should be used to tell it apart from Common Buzzard. The subspecies cirtensis (N. Africa, Sinai) has less marked carpal patches and is smaller than the nominate. Immature birds shows more barring on tail and less marked trailing edge to wing. Soars with wings raised to a V, as opposed to the very similar dark morph of Common Buzzard B.b.vulpinus. Flight action heavier and more eagle-like than Buzzard. Often perches on ground.

Sound:

Similar to Rough-legged Buzzard, but softer toned.

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.

Most commonly heard migratory call, a short "kut" or "knot". Sometimes given in stuttering series. Song an undulating, nasal mewing "poooor-mee", or "po-hor-mee".
