With the aid of the types of this bird before us, kindly lent us by the authorities 

 of the United States National Museum, we have no difficulty in recognizing it as 

 distinct from F. cestim, the characters having been carefully drawn by Mr. Ridgway 

 when first describing it ^. 



The range of P. cooperi appeairs to be very limited. Dr. Cooper found it abundant 

 near Fort Mohave in the Colorado valley, and Dr. Coues at Los Pinos in New Mexico. 

 Thence it has been traced southward to Mazatlan ^ ^ whence we have a fully adult 

 male from Mr. Forrer. The most southern point of its range mentioned by Brewer is 

 Colima, but on whose authority is not stated 3. 



Grayson says it makes its appearance at Mazatlan during the winter months, and he 

 saw it late in the spring, but not in summer ; but it was not common ^.
