The oak titmouse (Baeolophus inornatus) 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. It often builds its nest in a woodpecker hole. A common breeding resident in southern California, its species name, inornatus, means “plain,” appropriately for this very drab-plumaged bird. The history of the titmouse name goes back to medieval England around the 14th century. In Old English, 'mase' was used for birds and 'tit' for depicting anything small in size.
