with cover of dense grass and scattered bushes.

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.
Eggs: 3-4, sometimes 2-5. Pale bluish white, unmarked. Incubation is probably by female, but details not well known.
