BIRDS OF COLORADO. 
168 
ago the present writer saw at Glenwood Springs two mounted 
males that were taken near Newcastle the spring of 1892. Mr. 
B. L. Berthoud writes that he took one on Bear Creek near 
Golden in 1867 and also saw one in the Del Norte Valley, in 
September, 1883. That it should appear at the edge of the 
the plains is not wonderful, but the two records west of the 
range were entirely unexpected.

To previous records add one seen by H. G. Smith at Den¬ 
ver May 22, 1892.

One was taken by Mr. W. F. Doertenbach, near Pueblo, 
September 6, 1897. Two were seen and one secured.

Warbler. 
One adult and one young-of-the-year were taken on Teepee Creek, Car¬ 
bon County, Wyo., July 19, 1897, and one young-of-the-year near Reed’s Ranch, 
Albany County, Wyo., August 3, 1897. These specimens are now in the 
museum of the State University at Laramie City. All of these birds were taken 
near the Colorado line, making it practically certain that this species will yet 
be found in western Colorado. It is certain that these birds are ruficapilla of 
either the eastern or western form, but the above reference to the western form 
is given merely on geographical grounds. When the present writer examined 
the specimens he had no means of determining the exact variety.]

Warbler. 
Summer resident; rare. This species is brought among 
the breeders of Colorado on the strength of two nests found by 
Mr. C. E. Aiken, one in Colorado Springs and one near there. 
Mr. F. Bond writes that he has seen these birds several times 
at Cheyenne during migration.

According to Mr. Aiken this Warbler is not an uncommon 
breeder in the pinon hills north and east of Canon City. It 
arrives early in May.
