Reaches as far north in summer as Denver, Colo., where I obtained a 

 specimen May 10. 



A beautiful adult male of this variety of the Summer Tanager (P. 

 (estiva) Avas taken on the Gila River, Arizona, 1873, September 1G, and 

 another heard in same locality ; also noted on the San Francisco River 

 October 10. In each instance, they were found in the tall cottonwoods, 

 actively engaged searching for insects. 



None of these birds were seen in 1874 ; yet frequently, south of the Gila 

 River, I heard mention made by the settlers of the abundance of a " Red 

 Bird ", which was everywhere stated to inhabit the cottonwoods along the 

 streams. It was doubtless this tanager, which seems to confine its 

 range to the low valleys, and migrates to the south very early ; only an 

 occasional straggler occurring by the middle of September. The plates 

 respresent male and female specimens taken by the Expedition.
