Taxonomic Comments
Formerly considered part of B. inornatus, but B. ridgwayi split off by AOU (1997). Renamed B. griseus (griseus was original subspecific epithet given by Ridgway) in AOU (1998), but returned to B. ridgwayi by AOU (2000) because of previous nomenclatural difficulties. Constitutes a superspecies with B. inornatus (AOU 1998).

Range Extent Comments
RESIDENT: south-central Oregon, Nevada, southeastern Idaho, southwestern Wyoming, and south-central Colorado south (east of Sierra Nevada) to southeastern California, central and southeastern Arizona, extreme northeastern Sonora, southern New Mexico, and extreme western Texas (AOU 1998).
Ecology & Habitat

Habitat

ALL SEASONS: Pinyon-juniper woodlands (AOU 1998). In Wyoming, preferred pinyon-juniper woodlands with high overstory juniper cover and senescent trees (Pavlacky and Anderson 2001). BREEDING: Nest constructed in natural tree cavity, in old woodpecker hole, or bird box; 1-11 m above ground.

Ecology

Unlike most parids, exhibits pair territoriality in the non-breeding season. This behavior is associated with the species' dependence on large seeds (juniper and pinyon pine) and acorns, rather than arthropods (Christman 2001).
