BIRDS OF COLORADO.

“This paler Western Goldfinch occurs in Colorado as well as 
the typical eastern form to which all have heretofore been re¬ 
ferred. I am not able at present to define their relative range or 
abundance with certainty. Pallidus is an early spring migrant 
along the eastern base of the mountains, and quite likely may be 
the alpine breeder. Tristis probably is a summer visitor from 
the southeast, occupying the plains to the base of the mountains. 
I have obtained both forms at Colorado Springs, and tristis one 
hundred miles eastward. Examples of both forms, which I 
recently sent to the American Museum of Natural History, have 
been kindly identified by Mr. Chapman with the concurrence of 
Dr. Allen.”

Mr. Wm. Cross found this form breeding at Glenwood 
Springs during the summer of 1898. Mr. Aiken saw a very early 
flock at Colorado Springs May 13, 1898.

Found by Mr. Wm. Cross breeding at Glenwood Springs 
during the summer of 1898. This is the most northwestern 
record in Colorado.

One taken by Mr. A. T. Allen in Denver and identified by 
Prof. J. A. Allen. There is also one in Mr. C. E. Aiken’s collec¬ 
tion taken near Colorado Springs. Near Trinidad, in June, 1898, 
the present writer is very sure that he saw two of them, though 
he failed to secure either of them. The species is entered as seen 
in summer but not known to breed. This is according to the 
present record, but it is with the belief that the species occurs at 
Trinidad as a regular summer resident.

One of the few nests ever found on the plains is the one 
taken by Mr. F. M. Dille in the outskirts of Denver during the 
summer of 1898. Mr. Carter has taken it at Breckenridge.

Miss Myra Eggleston reports that they leached Grand 
Junction during the fall of 1899, a flock of a dozen being seen. 
This is the first record for Colorado west of the range, and there
