Cooper's Summer Tanager 

 HABITS 



This western race of our well-known summer tanager is decidedly 

 larger than its eastern representative, with paler coloration. Its 

 range includes the southwestern corner of the United States, from 

 middle Texas to New Mexico, Arizona, and the lower Colorado Valley 

 in extreme southeastern California, and extends southward through 

 western Mexico to Colima. The report of its accidental occurrence 

 in Colorado has been shown by Gordon Alexander (1936) to be an 

 error. 



In Arizona, we found Cooper's tanager common only in the lower 

 valleys, particularly along the San Pedro River, where my companion 

 Frank C. Willard took a set of four eggs on June 9, 1922. Swarth 

 (1904) reports it to be "of very rare occurrence in the mountains, 

 during migration." We did not see it in the mountains at all.
