Nondescript save for its crest, the Oak Titmouse might not wow many bird watchers at first sight. But these vocal, active birds characterize the warm, dry oak woods from southern Oregon to Baja California—they’re “the voice and soul of the oaks,” according to one early naturalist. Mates pair for life, and both partners noisily defend their territory year-round. The Oak Titmouse and the nearly identical Juniper Titmouse of the Great Basin were once treated as a single species, the Plain Titmouse.
The Oak Titmouse sleeps in cavities or in dense foliage. When roosting in foliage, the titmouse chooses a twig surrounded by dense foliage or an accumulation of dead pine needles, simulating a roost in a cavity.
