Pale gray upperparts. Underparts are paler gray than upperparts. Small crest. Small black bill. Dark legs. Sexes similar. 5.75 inches in length.
Broadleaf woodlands, especially oak and pinyon-juniper.
5-8 white eggs sometimes marked with reddish-brown spots. The eggs have a 14-16 day incubation period. Fledging occurs in 16-21 days. The female incubates the eggs, while the male feeds the female. The nest, which is composed of grasses, fur, and some feathers, is built in a tree cavity, fence-post hole, or crevice of an old building.
