Very local and nomadic in lower foothills of the Andes. Favors dry stony slopes and canyons, but ranges readily into nearby fields and scrubby areas. Usually in flocks and in areas where other yellow-finches do not occur, but associates readily in fields with other seed-eating birds. Male suggests Bright-rumped Yellow-Finch (of high Andes), but has dark streaking on back, a stouter bill, and a duller yellowish rump. Female is drab overall, but with distinct dark back steaking and a stout bill; usually in company with males.
