The Wilson Bulletin 



/s a quarterly journal devoted to 

 the study of the birds as we find 

 them in the fields and woods. 



It is particularly concerned about the study 

 of the whole life-history of each species, 

 amd about the effects of advancing civiliza- 

 tion upon the lives of all birds. It urges 

 the great importance of making a census 

 of our bird population for the purpose 

 of determining accurately what change 

 there may be in numbers due to changing 

 conditions. It is the official organ of the 

 Wilson Ornithological Club, which num- 

 bers among its members some of the 

 most prominent American ornithologists. 

 Carefully selected illustrations appear in 

 each number.
