Appearance:

Huge bird of prey with almost white head, neck and ruff. Body buff and wing-coverts pale buff in marked contrast to dark flight-feathers (opposite of Black Vulture). Silhouette typical with small head and short tail. Wings with S-shaped trailing edge, and very long and widely separated primaries. Soars with wings raised in shallow V. Glides on bowed wings, with slightly folded and depressed primaries.

Sound:

Quite vocal for a vulture, but generally silent in flight. Various shrieking high notes, hissing, and harsh cackling sounds.

Appearance:

Rarely seen, small petrel. Compact with shorter wings and tail, and blacker plumage than Leach's Storm-Petrel. Squared, unforked tail. White patch on upper tail coverts that reaches down on each side, with more square-cut edges than in Leach's. Also lacks the grey upper wing-band of latter, but shows white stripe on underside of wing. Flight-pattern bat-like with quick fluttering wing-beats and less powerful, and only short, gliding sequences. Sometimes patters with feet on the surface or rests on water. Visits breeding ground at night.

Sound:

Heard at breeding ground. Dry, cyclic, rattling and cooing, interrupted by deeper nasal moaning or a higher pitched "kee-ee-kee", with emphasis on second syllable.
