BIRDS OF COLORADO. 
Springs. As they are familiar with this species, as well as the 
more common A. candidissima, there appears no reason to doubt 
their identification.

So many records for Colorado are accumulating of this 
species that it must be counted as a regular summer visitant to 
the state, whether or not it breeds. Two more specimens are 
known from Denver; three known by Mr. Aiken at Colorado 
Springs the spring of 1899 ; one at Glenwood Springs the spring 
of 1898, while Mi’. Carter has not only taken them in Middle 
und South Parks, but even at Twin Lakes at 9,000 feet. A 
male and female were taken together by Mr. Carter, May 12, 
1896, on the Gunnison river.

“Temperate North America.”—(A. O. U.) Common summer resident 
of Nebraska and Kansas. Also known as common in the states west of Colo¬ 
rado. Should be noted before long from Colorado.

In 1875 Mr. Aiken found them breeding at the San Luis 
Lakes and secured eggs. The present writer also found them 
there in 1898. Mr. Carter has taken them in both Middle and 
South Parks. Mr. L. B. Gilmore saw them on Sweetwater Lake 
at 8,000 feet, which is one of the highest records for this species.

ago near Denver.

Mr. Carter has known of their breeding in Middle Park to 
about 8,000 feet, and Mr. Baker saw some November 15, 1899, 
in the Wet Mountain valley at about the same altitude.

In Goss’ “Birds of Kansas” this species is given as extending “West 
into Colorado.” There seems to be an error about this, and there is at present 
no undoubted record of this bird in Colorado. Since, however, it is a common 
species in Kansas and Nebraska, nearly to the Colorado line, we may expect 
sooner or later to have the above record verified.]

Taken by Mr. Aiken at the San Luis Lakes, June 30, 1875, 
and therefore breeding there at 7,500 feet. One was brought to 
Mr. Aiken that w T as shot February 16, 1899, at a spring five 
miles from Colorado Springs. It was a male in good condition,
