The juniper titmouse, Baeolophus ridgwayi, is a common and widespread bird in Utah that occurs in most parts of the western United States, as well as in parts of northern Mexico. As its name would suggest, it is often found in areas containing pinyon-juniper woodlands.

The juniper titmouse feeds on insects, seeds, and fruits. Breeding pairs are monogamous, usually remaining together from year to year. Tree cavities, including natural cavities and woodpecker holes, are used as nesting sites; nest boxes are also used when available. Any modifications to the existing holes are done by both sexes, and the female constructs a base of grass and bark. The nest is finished with a small cup of hair, fur, and feathers. The female lays six to eight eggs and incubates them for 14 to 16 days. Young are cared for by both parents and leave the nest after about 17 days, but they remain with their parents for an additional three weeks, until they are able to forage for themselves.
