Appearance:

Differs from Common Tern in shorter head, and blood-red bill. Legs shorter, but tail streamers longer (extends well past wings in sitting birds). Underparts of primaries with sharply bordered dark trailing edge (diffusely bordered in Common Tern). Both primaries and secondaries transparent to sunlight. Crest less apparent than in Common Tern and underside greyer. Cheeks white just below the black cap, often in contrast to grey lower cheeks. Juveniles lacks buff coloured back.

Sound:

Similar to Common Tern but higher pitched. Typical call a series of high pitched "tip-tip-tip", and longer, ringing, high-pitched "kriiiiii" calls. The drawn out "kree-aaahh" call falls less distinctly in pitch than Common Tern.

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.
