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.

Appearance:

Similar to Great Spottet Woodpecker, D. major in all plumages, but can be separated by the following fieldmarks: Moustache stripe does not connect to the black neck like in D. major, but this is often difficult to observe. Note also that young D. major may have similar (but smaller) gap. Tail almost black with just small white spots at edges of base (bold black and white edges in D. major). Nostril coverts white. Vent more pinkish than red, while red neck patch of male reaches further towards the crown. Immature birds may recall Middle Spotted Woodpecker, but note black border between crown and cheeks and long, powerful bill (like Great Spotted). Chest of immature often with pink wash.

Sound:

Contact call similar to D. major, but softer and not unlike alarm call of Redshank. Drumming also similar to D. major but longer (especially in males) and with marked lowering of volume at the end (diminuendo).
