Habitat Locally common summer visitor (mainly Apr-Sep) to dense chaparral- and scrub-covered slopes. Winters mainly in Mexico, but also in southwestern U.S.
Observation Tips Relative impenetrability of favored habitat makes observation challenging, but singing males are sometimes obvious in spring.
Range California, Northwest, Plains, Texas, Southwest, Rocky Mountains
Voice Song comprises a series of abrupt tchup notes followed by burst of chatters and whistles; call is a rather plaintive, upslurred mew.
Discussion Long-tailed bird. Not unduly wary, but remains within cover of scrub much of the time. Mainly terrestrial; scratches through leaf litter with both feet, feeding on insects and fallen seeds. Sexes are similar.
