Breeding

Both sexes build a football-shaped nest of dry grasses lined with feathers, with a small side entrance, placed in cactus plants. The clutch consists of 4-5 buff, speckled brown, eggs which are incubated by the female for 16 days. The male continues to build more nests for roosting and nesting sites. Both parents care for the young, who fledge in 19-23 days.
