THE BIRDS OF COLORADO 
BIRDS of THE ROCKIES 
WITH CHECK LIST OF COLORADO BIRDS 
BY 
DR. LEANDER S. KEYSER 
Author of ‘* In Bird Land” 
With eight full-page bird portraits (four in color) by 
Louis Agassiz Fuertes; thirty-three text drawings by 
Bruce Horsfaul; eight photographic views of moun- 
tain scenery showing the habitats of the birds, and an 
elaborate index. 
In Mr. John Burroughs’ recent paper in The Atlantic Monthly, 
on ** Real and Sham Natural History,” he said: ‘* Mr. Leander 
S. Keyser’s ‘ Birds of the Rockies’ tells me just what I want to know 
about the Western birds — their place in the landscape and in the 
season, and how they agree with and differ from our Eastern spe- 
cies. Mr. Keyser belongs to the noble order of walkers and tramp- 
ers, and is a true observer and bird-lover.” 
‘* The book is beautifully illustrated. . . . Mr. Keyser is an intel- 
ligent observer and has a good general knowledge of his subject. 
. . A book that is well worthy of extended sale, and which occu- 
pies a hitherto somewhat neglected field in the list of popular bird 
books.”— Dr. J. A. Allen, in The Auk, New York. 
‘*Mr. Keyser abandoned himself to the fascination of bird-study 
on plains and foothills, mountain parks and peaks, and his recountal 
of his experiences cannot fail to arouse the spirit of desire in the 
minds of those who follow his pages. The book possesses scientific 
as well as literary value.”— Frank M. Chapman, in Bird-Lore, New 
York.
