The Birds of El Paso County, Colorado 579 



Stelgidopteryx serripennis. Rough-winged Swallow. 



Summer resident; common. Arrives about May 10; de- 

 parts with the other species. 



This species, while fairly common, is somewhat locally 

 distributed in the breeding season, owing to the comparative 

 lack of suitable nesting sites. Full-fledged young of the year 

 were taken along Monument Creek, north of Roswell, July 

 23, 1899, by Aiken. 



Bombycilla garrula. Bohemian Waxwing. 



\A'inter visitor ; irregular ; not seen at all many winters. 



The first note we have of this species is January, 1872. 

 when Aiken saw a flock in Barnes's Canon, near Turkey Creek, 

 and a note that" Carter killed one on Pike's Peak the fall of 

 1871. 



There are specimens in the Aiken Collection taken on 

 Cheyenne Mountain, January and February, 1880. There were 

 some around the winter of 1910-11, and they were in Colorado 

 Springs, February 26, 1911. 



Aiken noted at Salt Lake City, Utah, in 1895, that in the 

 late afternoon the Waxwings, which had been about neglected 

 crcharfls near the town feeding on the apples still hanging 

 to the trees, began to fly in flocks up the canons toward the 

 mountains, evidently going to their roosting places in the 

 green timber. 



Bombycilla cedrorum. Cedar Waxwing. 



"Noticed only two or three times and in the earlier part 

 of the winter." Aiken List, 1872. 5 or 6 seen on Beaver Creek 

 by Aiken, October 17, 1872. This was just over the line into 

 Fremont County. Several were also seen by him just south 

 of Colorado Springs, August 8, 1897.
