These birds defend their territory year-round, but males are generally less territorial in the summer months during molting and the fledgling dispersals. Males may give a visual display to intruding males by employing a head down position, showing off their crissum (the undertail coverts surrounding the cloaca) while simultaneously disappearing into a bush head first in a slow motion. Their territories are most actively defended from early December to early February. Potential competitors for food and nesting sites include the northern mockingbird, sage thrasher, loggerhead shrike, house finch, black-throated sparrow, cactus wren, and the greater roadrunner. They may share the same nesting shrub or tree with their competitors, such as the loggerhead shrike.
