Appearance:

Unmistakable. Grey, cliff-climbing bird with long, thin and curved bill. Wings with colourful pattern in carmine red, black and white spots. Habitually flicks wings when foraging (see videolink below), but still hard to spot when not flying. Flight jerky and butterfly-like, and also recalls Hoopoe. Wings appear dark from below, except for white pearls on primaries. Male with blackish throat in breeding season.

Sound:

Alarm call a thin trilling "vuiirrrrrrr". Flight call one or several soft whistles, often with (very) short trill as attack or tail. Song variable in length, but main characteristic a sequence of 4-6 long, ascending whistles with timbre recalling whistling kettle. More complex and varied phrases are mixed with the long whistles. Both male and female sings.

Appearance:

Large shearwater with distinct, marked, dark cap and white collar. Blotched belly and underwings. White upper tail-coverts forms a horseshoe mark, but note that Cory's Shearwater may show the same. Dark patch at side of neck. Bill dark. Flight action powerful, with alternating glides and rapid bursts of beats with stiff wings. Seldom soars.

Sound:

Calls at breeding ground a deep, soft, moaning "oooh-aahh" ("surprised or shocked old lady"). Tone fairly clear, and pitch rising and falling.
