pp. 27, figs. 23, February 13, 1915. 
In this bulletin are discussed the food habits of 59 species of birds. 
The bulletin was prepared to take the place of Farmers’ Bulletin 54 origi- 
nally issued in 1897 which contains summaries of the food habits of 28 
species and brief references to the nature of the food of 8 others. The 
revised edition (1904) contains 40 specific summaries and notes on 14 
species. Farmers’ Bulletin 630 is the one article on bird food to have if 
the complete series of bulletins and other publications of the Biological 
Survey is inaccessible. Many of the food summaries, though brief, are 
important, being based on the examination of large numbers of stomachs. 
Farmers’ Bulletin 630 and its forerunners have been reprinted more 
than 50 times and a total of over a million copies have been distributed.
