Appearance:

Medium sized eagle with long wings and tail. Pale base of outermost primaries in all plumages (lacking in Booted Eagle). Adults easily identified by dark greater coverts forming mid wing band on underwing, in combination with pale body and pale lesser coverts (variable). Tail clear cut (but not as pointed corners as in Booted Eagle) with broad terminal band. Back with diagnostic white patch (variable). Immature told from dark and medium morph of Booted Eagle by pale base of outer primaries, narrowly and evenly barred tail (bands reaching outer edge). The species show less fingered wings than many congeners, and long tail combined with small head may recall Honey Buzzard. Characteristic gliding profile with projected carpal joints and straight trailing edge of wing. Slight S-shape to trailing edge of wing when soaring. Flight agile and falcon-like.

Sound:

Not very vocal, but may call at breeding ground. Commonest call a sharp, gull-like "kleeee", beginning with marked register-break followed by drawn-out note with fairly stable pitch, unlike most congeners.

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.
