Appearance:

Small, 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.

Appearance:

Differs from Common and Arctic Tern by; noticably shorter wings, longer streamers, much paler grey upperparts, pure white underparts (faint rosy wash not very conspicuous), black bill (red base in breeding birds), dark outer primaries and no dark edge to inner primaries. Amount of red in bill increases as breeding season progresses, but also varies geographically. Wingbeats shallower and much quicker than in Common and Arctic Tern. Fishes with characteristic diagonal dives. Despite the long streamers, the birds appear short-tailed in flight, but head and bill are long and slender. The pale plumage, dark bill and giss recalls a small Sandwich Tern. Adult winter plumage with all dark bill and white forehead. Juveniles resembles juvenile Sandwich Terns, with more complete dark cap than Arctic and Common, and much more contrasting markings on back (especially to wings).

Sound:

Extremely harsh calls. Like mix of Caspian and Arctic Tern. Very hard and raspy "kreeeet", harder and higher pitched than Caspian Tern, but equally harsh. Other calls include more Arctic/Common tern-like short "kek", and similar.
