Feeding Behavior
Forages mostly while walking or hopping on the ground, but also will feed up in weeds and low bushes. Tends to move slowly, foraging in a limited area. Usually forages in pairs or in family groups.
Eggs
3-4, sometimes 2-5. Pale bluish-white, unmarked. Incubation is probably by female, but details not well known. Young: Both parents feed the nestlings. Young probably leave the nest after about 8-9 days, before they are able to fly; young may remain with parents for up to several months.

Diet
Mostly insects and seeds. Diet varies with season and locality, but tends to eat more insects in summer, more seeds in winter. Major items in diet may include caterpillars, beetle larvae and adults, grasshoppers, ants, and other insects and spiders. Also eats many seeds of grasses and weeds at all seasons, but especially in winter.
Nesting
Members of a pair may remain together all year on permanent home range. In spring and summer, male sings to defend nesting territory. Nest site is usually on the ground, typically well hidden at base of bush or grass clump, placed in a slight depression so that rim of nest is near ground level. Occasionally in low shrub, up to 1-3' above ground, especially in eastern part of range. Nest is an open cup made of small twigs, grass, weeds, plant fibers, often with some animal hair in lining.

Song is a rapid, pleasing jumble of notes, recalling that of the House Wren, but with "sparrow quality." Distinctive call is a down-slurred dear dear dear and a thin, plaintive tseeee.Learn more about this sound collection.
