Little Auk (Alle alle)
River Warbler (Locustella fluviatilis)
Small and compact auk. Bill short and blunt, tail and wings short. Scapular feathers with characteristic white brims. Differs from young Puffin by white "thighs", white throat and only faint neck collar (in winter). Often difficult to spot when swimming in waves, and more often seen when flying. Take-off from water surface easy and direct. Flight less constricted than larger auks, and changes direction frequently and with ease.
Sound:Voice higher pitched than other auks (except Black Guillemot). Trilling, rolling and chattering laughter "kreeee he he he he", or shorter, softer utterances; "ke ke" or "hup hup".

CCSounds:Recorded by Stein Ø. Nilsen,http://www.xeno-canto.org ,CC license
A long-tailed and relatively long-winged Locustella, with olive-brown plumage and pale belly. Conspicuously broad, rounded tail, and substantial vent. Under tail coverts brown with with prominent pale fringes, and almost reaches tail tip. Faintly streaked throat and breast. Rump and tail warmer brown than back. Faint and short supercilium and pale eye-ring. First long primary with pale outer web, and a slight curve. Song-posts often more exposed than Grasshopper Warbler.
Sound:Song an insectlike, buzzing like Grasshopper and Savi's Warbler, but easily distinguished from those by it's distinct steam locomotive-like rhythm. About 8 accents per second. Perhaps easier to confuse with certain species of ground crickets or cicadas than it's congeners. Contact call a sharp "tsikk-tsikk", similar to Savi's Warbler.
