Appearance:

Summer: Black throat framed in fine white stripes at the sides, and a chequered black back. Winter: More contrast between dark and white parts than in Red-Throated Diver. Marked transition between dark neck and white front, and the dark grey crown extends below the eye. In all plumages: Heavier neck and bill than Red-Throated, and bill usually held straight. Visibly protruding chest when swimming. Head shape sometimes squarish. Usually shows big white flank patch.

Song: a strong, very resonant, full bodied, low whistling with most syllables rising in pitch: "co clooo-eee, co clooo-eee, co clooo-eee". Also a short grunting "karr".

Appearance:

Europe's biggest raptor. All dark vulture with short, wedge-shaped tail and very long and broad wings. Legs pale, and usually readily visible. May resemble White-tailed Eagle or Greater Spotted Eagle at distance, but note short neck, less protruding head, even longer and broader wings, and shorter tail. Under wing-coverts darker than flight-feathers. Trailing edge of wing fairly straight compared to S-shaped edge in Griffon Vulture, making the overall wing-shape more squarish. This is most obvious when soaring on stretched wings. Soars with wings leveled, not raised, often with hand lowered. Frequently raises tail just before landing.

Sound:

Voice little used but varied. Grunts,croaking, mewing, hissing etc. heard when breeding or feeding at carcasses.
