Oak Titmouse
Oak Titmouse
Baeolophus inornatus
At a Glance
As plain as a bird can be, marked only by a short crest, the Oak Titmouse nonetheless has personality. Pairs or family parties travel about the woods together, exploring the twigs for insects and calling to each other frequently. Until recently, this bird and the Juniper Titmouse were regarded as one species under the name of Plain Titmouse.

Also will use nest boxes, and sometimes crevices in buildings or other cavities. Nest has foundation of grass, weeds, moss, bark fibers, and lining of soft material such as feathers or animal hair.
