 species are seen. 



Baeolophus inomatus griseus. Gray Titmouse. 



Found only in the cedar and pinon region in the extreme 

 southwestern portion of the County, where it is resident, and 

 was found by Aiken to be common in winter but scarce 

 in summer. It was less common in December and January than

 deciduous trees. It nests in the valleys as well as in the hills 

 and Aiken's notes contain the following description of a nest

 Breaking away part of the bark I found a considerable 

 excavation, about 10 inches deep, with the bird sitting closely 

 at the bottom. A twig that I reached down to her she seized 

 in her beak and allowed herself to be lifted by it nearly to the 

 top. I was obliged to break away more bark to reach the
