The Oak Titmouse and Juniper Titmouse appear identical, but differ in voice as well as range. In general, the bird is brown-tinged with a plain face and short crest, and measures 5.75 inches in length. The Oak Titmouse gives a repeated series of three to seven syllables, each comprised of one low and one high note, while the Juniper Titmouse song consists of a series of rapid syllables on the same note.

Taxonomy

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.

Subspecies

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

Habitat

Open oak and pine-oak woodlands.

Behaviour

Breeding

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

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