Very small quail of open brushy woodland and weedy fields in dry regions; endemic to interior southwest Mexico. No other quail in most of its range and habitat. Occurs in coveys for much of year, usually of 5–15 birds, which often feed along quiet roadsides early and late in the day. Flushes explosively with shrieking chatter when disturbed. Sexes look alike, with dark crest spike and boldly barred belly.
