The Birds of El Paso County, Colorado S8S 



describes as follows: "June 24, [1880] at Seven Lakes, I found 

 four eggs almost ready to be hatched. These are curiously 

 like a common type of the Yellow Warbler's, being greenish 

 white, marked, chiefly about the crown, with olive brown 

 and neutral tint and averaging about .70x.S5 of an inch. The 

 nest, composed of shreds and feathers, was built in a dead 

 bare spruce, about twenty feet from the ground, compressed 

 between the trunk and a piece of bark that was attached be- 

 neath and upheld above, where a bough ran through a knot- 

 hole; so compressed that the hollow measures 2j4xl^ and 

 1 1-3 inches deep. Such a position for the nest is not unusual, 

 for I more than once saw the birds about dead timber." 



Audubon's Warblers are usually common in the trees and 

 bushes along the streams on the plains and in the foothills in 

 the spring from their first arrival until the middle or latter 

 part of May. A late valley record is one taken June 5, 1904, at 

 Fountain, by Aiken. On the whole it is the most common 

 warbler we have. 



Dendroica striata. Black-poll Warbler. 



Migrant; rare. The only records are of spring birds. 

 Allen and Brewster noted it May 8 and 9, 1882, at Austin's 

 Bluffs. Aiken took one May 18, 1872, on Turkey Creek ; May 

 8, 1904, at Fountain; June 1, 1907, at Skinner's. 



Minot, 1880, recorded it as "local summer resident about 

 Seven Lakes." This record is open to question. Minot col- 

 lected no specimens, and the locality is so far south of any 

 other known breeding station of the species that the record 

 had best be disregarded until substantiated by specimens 

 actually taken. 



Dendroica nigrescens. Black-throated Gray Warbler. 



Local summer resident. Arrives about the first week in 

 May, Aiken having taken his first specimen May 6, 1872. 



As far as we know this species is confined in El Paso
