Small, short-tailed, flat-headed sparrow found in weedy grasslands. Warm buffy coloration with clean unstreaked breast. Thin white eyering and yellow patch above eye. Back and wings are patterned with gray and rufous. Easy to see when singing atop a shrub, but can be very secretive much of the year. Best detected by its dry, insect like trill preceded by a few introductory notes. Typically not in flocks.
