Great Shearwater (Ardenna gravis)
Little Grebe (Tachybaptus ruficollis)
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.

CCSmall, dark grebe with bright yellow gape, short neck and bill. Winter plumage paler than summer, with chestnut flanks, neck and cheeks, giving much less contrast between upper- and underparts than in Slavonian Grebe. Fluffy, pale stern. No crest or tufts/tippets and no white markings on wings.
Sound:Relatively vocal compared to many other grebes. Call; sometimes a single quite clear high pitched "dydlylyyt". More often combined into longer phrases with harsher quality, oscillating like laughter and travelling up and down in pitch in agitated motion. Reminiscent of female Cuckoo.
