Black-necked Grebe (Podiceps nigricollis)
River Warbler (Locustella fluviatilis)
Small and dark grebe, with squarish head and thin, uptilted bill. Adult breeding plumage distinct, with unique combination of black head and neck, and a spray of golden, fan-like feathers from eye to nape. Winter plumage birds are easily confused with Slavonian Grebe, but note dark, rear cheek-patch, and darker collar. Head profile distinct, with its steep forehead. In winter plumage highest point is above the eye, as opposed to nape in Slavonian. Much more contrasting plumage than Little Grebe. Avoids to take wing if possible.
Sound:Territorial song a disyllabic, flute-like "zoeeee-chk". First part drawn, ascending and plaintive, second part descending and clipping. Timbre is unpure. Other calls include chittering and trilling calls resembling Slavonian or Little Grebe.

CCA 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.
