Oak Titmouse

This species lives year-round on the Pacific slope, resident from southern Oregon south through California west of the Sierra Nevada to Baja California, but its range surrounds the central San Joaquin Valley. It prefers open woodlands of warm, dry oak and oak-pine at low to mid-elevations but can also be found in forests as long as adequate oak trees are present. With these habitats, the oak titmouse lives typically in Quercus agrifolia (coast live oak) and Quercus lobata (valley oak); which provides sufficient cavities, dense foliage, and twig piles that those oaks provide, oak titmouse utilizes such sources for nesting. However, the rural residential sprawl and vineyard development caused California oak woodlands to experience a rapid threat due to habitat fragmentation. Specifically, following with the low predation, it has contributed to oak titmouse’s high nest failure. Thus, in protecting such species, California habitat conservation actions are needed. According to the Red List provided by the IUCN, the conservation status of oak titmouse is now listed as Least Concern. The population of California’s oak titmouse is under threat from many human activities, including increased wildfire frequency caused by humans, clearing for agriculture and urban expansion. …
