NOTES: (Behavioral Context: mate contact?, parent-young contact?; General Climate: arid; Cover Density: sparse) "Zweer" calls, the first one given in flight and subsequent ones while perched on sagebrush. The announcement "Western Kingbird" is in error. [Most of the calls here represent the fully peaked form of the Initially Peaked Vocalization (IPV; following Smith, W. J. 1970. Displays and message assortment in Sayornis species. Behaviour 37: 85-112), but there are additional calls that sound much like the "peeping" of young birds (e.g. 0:26-0:28, 0:30, 0:32), although no such vocalization is mentioned in account. Quality added (2-3, 2 - better later in cut) - 4 April 2005]. Other Behaviors: Perform Visual Display, Social Context: Family. Habitat: Chaparral, Scrub, Rocky.
