Until recently, Oak Titmouse and Juniper Titmouse were considered parts of the same species called Plain Titmouse, Baeolophus inornatus. Because the Oak Titmouse inherited the scientific name from the parent species, there can be problems with which exact species is found using the gallery search below. There have been further proposals to split the subspecies cineraceus from Oak Titmouse into its own species which would then be called Cape Titmouse and be resident in Baja California.


Four subspecies are recognized[1]:

  • B. i. inornatus

South-western Oregon and northern California south to southern California (Santa Barbara and Kern counties)

  • B. i. affabilis

Southwestern California (Ventura County) to northern Baja California

  • B. i. mohavensis

Little San Bernardino Mountains of southern California

  • B. i. cineraceus

Cape district of southern Baja California


Open oak and pine-oak woodlands.



The female builds nest with grass, moss, feathers, shredded bark in tree cavities. Incubation is 14 to 16 days, and young fledge in about 17 days.


Diet includes seeds, mostly from oaks, and a variety of invertebrates including leafhoppers and treehoppers.
