PROJECT LX. How to Study Bird Life (Independent Project) 



Three bulletins of the United States Department of Agriculture 

 make a very good introduction to the study of the common birds : 



"Fifty Common Birds," Farmers' Bulletin No. 513 (15). 



"Bird Houses and How to Build Them," Farmers' Bulletin No. 

 609. 



"The English Sparrow as a Pest," Farmers' Bulletin No. 493. 



Among the most reliable and usable manuals for the identification 

 of North American birds are the following : 



"What Bird Is That?" Frank M. Chapman. D. Appleton & 

 Co., 1920. This is the most usable handbook of birds for the United 

 States east of the Rocky Mountains. Every land bird in that section 

 is pictured in color. The color plates group the birds according to 

 season, and indicate the relative sizes of birds. The accompanying 

 text is simple but thoroughly adequate. This is not an expensive 

 book. 



"Color Key to North American Birds," Frank M. Chapman. 

 D. Appleton & Co., 1912. The title indicates the character of this 

 book. It is a guide to bird study throughout the North American 

 continent. 



" Birds of the Rockies," Leander S. Keyser. A. C. McClurg & Co. 



" Birds of California," Irene Grosvenor Wheelock. A. C. McClurg 

 &Co.
