152 BULLETIN OF THE 



FALCONID^E. 



65. Falco peregrinus. Seen at the' Garden of the Gods, Castle Rocks, 

 and on Bear Creek, in the foot-hills southwest of Denver. 



Cij. Falco sparverius. Abundant everywhere. Very numerous in the 

 Garden of the Gods, where they appear to nest in holes in the rocks. The 

 old birds were seen to enter holes in the cliffs, and several broods of newly 

 fledged young seen there were evidently raised in the vicinity, although 

 there were no trees within several miles in which they could have nested. 

 The remarkable pinnacles of rock, rising vertically to a height of from 100 

 to 300 feet, which occur at this point, abound in holes admirably suited for 

 nesting-sites for these and other birds, while the only timber in the vicinity 

 consists of dwarfed piiions, pines, and cedars, with here and there a cotton- 

 wood along the neighboring creek. 



67. Buteo borealis. A large red-tailed hawk was frequent every- 

 where between Colorado City and Denver.

 persed. Next to the sparrow-hawk, the most numerous species of Fal-
