Horned Lark (Eremophila alpestris)
River Warbler (Locustella fluviatilis)
Breeding plumage: Yellow face with broad black moustache stripes and black lores. Black forecrown and thin black horns. Black breast band with blunt vertical extension towards throat (sometimes connects to moustache stripes). Black tail with white sides. Juveniles covered in small pale spots with only faint facial markings. May be confused with juvenile Skylark, but note shorter bill and yellowish face of young Shore larks.
Sound:Song a stream of thin and tinkling, squeaking notes with a recurring, drawn, ringing and slightly ascending chirp. Timbre resemblant to Lapland Bunting. Often given from high in the air, being difficult to locate. More hesitantly when given from the ground with a stumbling introduction. Flight call quite similar to Meadow Pipit's "tseep" call, but less anxious.

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.
