8 BIRDS IN THEIR RELATIONS TO MAN. 



tain amount of excellent food. This game might also easily 

 become a source of revenue to many other people in the 

 town by attracting city visitors for the shooting season. 



In the following pages we have attempted to discuss in a 

 broad yet specific way the relations of birds to man as illus- 

 trated in temperate North America. The book has been 

 made possible only through the labors of such investigators 

 as Forbes, Merriam, Beal, Barrows, Fisher, Palmer, Judd, 

 Warren, Herrick, Montgomery, and many others, upon whose 

 published results we have freely drawn. The need of the 

 book was first shown when the senior author undertook to 

 teach a college class the subject of economic ornithology, and 

 its first draft consisted of the lectures prepared for that class. 

 When later the junior author — a life-long student of birds — 

 became associated with him, a joint study of the whole sub- 

 ject was undertaken, the results of which are here presented. 



A considerable proportion of the illustrations in this book 

 are from original photographs — chiefly of mounted specimens 

 — by the authors. The others have been gleaned from vari- 

 ous sources, which are credited beneath the pictures.
