A PARTIAL BIBLIOGRAPHY OF THE ECONOMIC 
RELATIONS OF NORTH AMERICAN BIRDS 
BY CLARENCE M. WEED 
The importance of birds as checks upon the undue increase 
of noxious insects has long been recognized by observing men 
scattered here and there throughout the United States. But a 
general appreciation of the value of these feathered allies is of 
comparatively recent development, and in some regions they 
are still unappreciated. 
The literature which has led to a wider knowledge of the 
value of birds has been scattered through many publications, 
much of which is inaccessible to the general reader, and some 
of it difficult to obtain even by the specialist. In the follow- 
ing pages I have attempted to bring together a bibliographic 
list of the more important articles treating of the economic 
relations of our birds. In compiling it I have had the help 
of Messrs. A. F. Conradi, W. F. Fiske, and R. A. Cushman, 
wdiile assistants in the entomological department of this station. 
For a number of citations of articles in Forest and Stream I 
am indebted to the pages of The Auk , while a few others have 
been gleaned from various other sources. It has been im- 
practicable to include citations of the great mass of literature 
treating specifically of game birds, or their acclimation and 
domestication, as well as of the thousands of references to the 
English sparrow, and of the many general bird books of recent 
years.
