A Census of the Birds of the United 

 States. 



During the summer of 1914, the 

 Biological Survey took initial steps 

 toward a census of the birds of the 

 United States for the purpose of as- 

 certaining approximately the number 

 and relative abundance of the different 

 species. In view of the recognized 

 value of birds to agriculture, such in- 

 formation cannot fail to be of great 

 value. The census will need to be re- 

 peated for several years before a satis- 

 factory basis can be obtained for safe 

 generalization. 



It is estimated that there are 

 100,000,000 robins east of the Missis- 

 sippi or fifty pairs to the square mile. 



There are one thousand pairs of 

 birds to the square mile east of the 

 great plains, and in the Montana for- 

 ests there is one bird pair to each 

 three acres. 



One of the principal values of the 

 census will be its use for various so- 

 cieties which undertake to protect 

 bird life. 



Twenty-seven states lack hunters' 

 license laws, and there is but a min- 

 ority with efficient game commissions. 

 In some Southern states the killing 

 of the bobolinks is still permitted. —
