ers were there also and seemed as much afraid of the hawk as 

 any of the others, though so near its own size. A number have 

 been noted in the park and nearby the last year or two, espe-

Accipiter cooperi. Cooper's Hawk. 



Summer resident, not common, arriving in April. An 

 early date is March 21, 1900. 



Astur atricapillus atricapillus. Goshawk. 



Winter resident, rather common. 



Three specimens in the Aiken Collection, from Monument, 

 near Colorado Springs, and El Paso County, respectively, are 

 labeled as belonging to the typical form. How destructive this 

 species can be to game and small birds is shown by the food 

 of one killed near Piiion, February, 1909. The crop con-

 digested remains of a Blackbird and another Scaled Quail. 



Astur atricapillus striatulus. Western Goshawk.

Four specimens in the Aiken Collection, two from Turkey

Summer resident, rare. 



There are two Redtails in the Aiken Collection which have 

 been referred to this subspecies, one taken near Colorado 

 Springs, September 27, 1902, the other at Manitou Park, Teller 

 County, August 29, 1906.
