Two shot out of three seen on Sheldon’s Lake, near Fort- 
Collins, October 29, 1898, by Wils Black. One of them is now 
mounted in the museum of the Agricultural College. 
This species has been seen by Edwin Carter in South Park,, 
but not taken.

Eared Grebe. 
Has been seen at Breckenridge in migration by Edwin 
Carter, and breeds abundantly in Middle Park. In the following 
pages many records of Mr. Carter are given which are not in a 
certain sense new records, since they would be implied by the 
knowledge of the occurrence of the species in neighboring local¬ 
ities, but they are entered here both as a record of Mr. Carter’s 
wide study of Colorado birds in localities not visited by other 
naturalists, and to furnish additional proof of the correctness of 
previous published records. Breckenridge is on the Blue River 
at an elevation of 9,500 feet, and about fifty miles from the 
junction of the Blue and the Grand rivers. Most of Mr. Carter’s 
records of “Middle Park” meant the country around the mouth 
of the Blue river, with an altitude of 7,000-7,500 feet. His ex¬ 
peditions cover considerable of South Park, but most of his 
collecting has been along the branches of the South Platte on the 
eastern side of the park at about 8,000 feet.
