BIRDS OF COLORADO. 
157 
Riyer, April 23, 1897, three of them were secured and 
have been mounted by Mr. Beymer. A young female, presum- 
ably of this species, was taken September 10, 1897, twenty 
miles east of Pueblo on the Arkansas and reported by W. F. 
Doertenback of Pueblo. It was not young enough to prove that 
it had been raised in the vicinity. 
In September, 1872, Mr. C. E. Aiken saw one on the South 
Platte River in South Park at nearly 7,000 feet altitude. On 
July I, 1875, Mr. Aiken found this species breeding at the San 
Luis Lakes at about 7,500 feet altitude, so that it stands at pres- 
ent in the Colorado list as a summer resident. 
The known northern range of this species is much extended 
by the following record. In the spring of 1893, Mr. R. A. Wal- 
len shot one at Red Bank, Wyo. , about two hundred miles 
north of Laramie City.

About August 5, 1897, W. A. Sprague of Boulder, 
saw a Least Bittern on a branch of the Grand River in Middle 
Park eight miles from Buchanan Pass. This is the first and 
only record for Colorado west of the range. Mr. H. G. Smith 
has one record of this species for the vicinity of Denver.

A very late migrant and also at a much higher altitude 
than the former records is the one reported by Mr. C. E. Aiken 
at over 9,000 feet on the divide between Colorado Springs and 
South Park, November 27, 1897.

This is probably not so rare a bird as was formerly believed. 
In addition to the seven records already noted, three specimens 
of this species were mounted by Mr. W. F. Doertenbach of 
Pueblo, during the past eight years; he also saw one on the 
Arkansas near Pueblo, May 9, 1897, and two young birds were 
sent him October 4, 1897, that were taken within six miles of 
Pueblo. 
Mr. C. E. Aiken adds five more records, two near Leadville, 
in 1886, one near Denver and two from Pueblo. The Leadville 
specimens at about 10,000 feet are several thousand feet higher 
than previous records.

A second record for Colorado comes from Mr. E. L. Berth- 
oud, who shot one near Golden eight years ago.
