THE 



Warblers of North America 



In treating the fifty-five species and nineteen subspecies of War- 

 blers, which have been found north of Mexico, I have followed the 

 order of arrangement adopted by Mr. Ridgway in his 'Birds of North 

 and Middle America', uniformity of method being in my estimation, 

 of more importance than the expression of individual opinion. In the 

 belief, however, that in the work just mentioned, Seiurus was 

 inadvertently inserted between Oporornis and Geoihlypis, I have 

 here placed it before these closely related genera. 



The inclusion in this book of one hundred and twenty-four 

 colored figures of Warblers is thought to make the presentation of an 

 analytical key to species superfluous. The appended summary of 

 their more striking generic characters and habits may, however, 

 prove useful :
