The Upper Sonoran zone occupies a comparatively limited area in the state, 

 and the list of birds confined to it solely is a short one. In southern Arizona this 

 zone is in few places of greater width than is comprised in the belt of live-oak 

 covered foothills between the higher mountains and the valleys below. Of the 

 seventeen species listed as peculiar to this zone, eleven are preeminently birds 

 of this live-oak association, as follows: OHis o, cineraceus, Dryobates arizonae, 

 Melanerpes f. aculeattis, Tyrannus vociferans, Myiarchns L olivascens, Aphelo- 

 coma zvoodhous.ei, Aphelocoma s. arizonae, Vireo A. stephensi, Baeolophus L 

 griseus, Baeolophtis wollweberi, Polioptila c, obscura. 



Of the remaining six, Cynanthus latirostris, Myiochanes r. richardsoni, and 

 Vireosylva g. swainsoni are to a great extent denizens of the sycamores along 

 the cafion streams in the foothills, Icterus parisorum and Aimophila ruHceps 

 scotti frequent the agave and scrub-oak covered hillsides, while Vireo vicinior 

 is in the denser brush of the same region.
