This species was first seen in the vicinity of Denver on the 12th of 



.Mil 



y- 



In Southern Colorado, a few pairs Avere seen during the breeding-sea- 

 son in the same localities as the White-bellied Swallow. This species, how- 

 ever, attains a much higher altitude, and at 10,000 feet I found it very 

 common and in large colonies. June 7, they had not begun to build, 

 though evidently about to do so in the high pine stubs. 



In Utah, New Mexico, and Arizona, this swallow inhabits the higher 

 regions, being met with in abundance everywhere in suitable localities. It 

 prefers the open spaces in the pine woods or along its edges, and occasion- 

 ally makes its homes in the oak groves, building its nest most usually in 

 the holes abandoned by Woodpeckers.
