Appearance:

Easily confused with Sandwich Tern but choice of habitat usually different. Adults differs by noticeably shorter and deeper bill, lacking yellow tip. Wings are broader, tail is shorter and only slightly forked. Lacks crest. Primaries with dark trailing edge, especially underside. Rump pale grey, and there is no contrast between grey back and white tail as in Sandwich Tern. Loses the black cap in winter, but keeps a black mask (less black on head than Sandwich T). Immature birds also gives a paler impression. The back is almost uniform in colour, and the wings also have only diffuse markings. The dark trailing edge to the primaries is present though, together with dark eye mask. Rest of head is pale. Flight slightly front-heavy with shallow wing-beats. Catches insects in the air and from the ground in flight. Rarely plunge-dives. Prefers fresh water, and is often seen near wetlands, rivers and flooded fields, but also in salt water during migration.

Sound:

Quite vocal and easily distinguished from most congeners. Mewing and sharp in tone, but not rattling or raucous like most terns. Most typical call is a disyllabic, mewing "ke-waat", with an upward inflection. Other variants are series of "ke-ke-ke-ke", or the mewing sounds.

Appearance:

Most likely to be confused with Little Crake (P. parva). Most important field characters is the very short primary projection and lack of red base of bill. Some caution should be taken as missing or unorderly tertials can be confusing with regards to the projection, and immature Little Crake may sometimes also lack red base of bill. Flanks and belly more extensively barred than P. parva. Upperparts richer brown with white spots. Sexes alike, but females often with paler throat. Brown cheeks occurs in both sexes. Legs dirty olive colour and bill greenish. Immature even more easily confused with P. parva, but apart from the missing projection, note warmer brown upperparts and more heavily barred underparts, even on breast. Crown less evenly coloured than P. parva, with blackish speckles.

Sound:

Rich repertiore. Male song easily overlooked due to similarity to The edible frog Pelophylax esculentus., and to being audible only a few hundred meters. The sound, a rolling "trrrrrrrr", differs from frogs in being drier and more stable in pitch. Sometimes the pitch rises slightly in the beginning of the call, but then remains stable also at the end. The call is uttered in 1-2 seconds intervals and each call is 2-3 seconds long. Some overtone modulation is common (stable pitch but change of vocal "ooeeii"). Unmated female sings with a more hurried "wirrr". Alarm call a series of nasal, hoarse "weeat" or a sharp "kriik".
