FURTHER NOTES 
ON 
THE BIRDS OF COLORADO. 
BY W. W. COOKE. 
Since the publication in March, 1898 , of the notes on Colo¬ 
rado birds that had been gathered the previous year, many 
additional notes have been secured. The largest number from 
any one source have come from a thorough study of the fine 
collection of Mr. Edwin Carter at Breckenridge. This collection 
represents the work of Mr. Carter for more than thirty years. 
Much of the material was gathered in the immediate vicinity of 
Breckenridge, and the rest in Middle Park and South Park. 
Breckenridge is at an altitude of 9,500 feet, while Middle and 
South Parks are from 7,500 to 8 , 500 , so that Mr. Carter’s collec¬ 
tion is especially valuable as showing the bird life of the 
mountains and mountain parks. Breckenridge is on the western 
slope of the main range, and this collection furnishes several new 
records for the Pacific side of the mountains as well as a higher 
range than before known for more than thirty species. The 
Carter collection contains 184 species of birds, of which 127 are 
known to breed in Middle and South Parks. Mr. Carter has also 
taken 16 species that are not now in the collection. The collection 
adds two new birds to the state, Ammodramus leconteii and Falco 
sparverius deserticolus, and one new breeding record, Wilso 7 iia 
pusilla pileolata. 
Much space is given to notes from this collection, because 
the recent death of Mr. Carter makes the collection complete so 
far as his work is concerned. No catalogue or summary of this 
collection has ever been published. The present writer made 
three visits to Breckenridge, and has studied every bird in the 
collection at least twice. The last visit was but a few days before 
Mr. Carter left home on that last trip from which he was not to 
return alive. On this visit a complete investigation was made of 
all Mr. Carter’s records of birds he had taken that are not now in
