Nests are typically placed low to the ground – no higher than 3 m (9.8 ft).  A clutch may consist of two to four eggs.

The mearnsi subspecies breeds in March and April; and the nominate race from May to mid-July.

They mostly build their nests with twigs and line them with various grasses and other softer material.  Nests are placed in cacti, thorny shrubs and mesquite trees.
