Western Bluebird

The western bluebird is a small North American flush found primarily in the western U.S. and Mexico. 

Range from Wikipedia. 

The male is bright blue on top and on the throat, has an orange breast and sides, a brownish patch on the back, and a gray belly and undertail coverts. The female has a duller blue body, wings and tail, a gray throat, a dull orange breast and gray belly and undertail coverts. 

I am seeing lots of them on the telephone lines on our street, but I've never seen one come to our birdfeeders in our backyard. 

The following are photos I've taken of western bluebirds:
