APPENDIX IV. 



A PARTIAL BIBLIOGRAPHY OF THE ECONOMIC RELATIONS OF 

 NORTH AMERICAN BIRDS. 1 



BY CLARENCE M. WEED. 



The importance of birds as checks upon the undue increase of 

 noxious insects has long been recognized by observing men scat- 

 tered here and there throughout the United States. But a general 

 appreciation of the value of these feathered allies is of com- 

 paratively 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 diffi- 

 cult to obtain even by the specialist. In the following 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 E. A. Cushman, while assistants in the ento- 

 mological 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 impracticable 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.
