 Contains conslse descriptions ot every species of biids known io North America. 

 Profusely Illustrated with 4(>4 outlii'e cuts of iht gtnerlc claracteis, and a poitnilt of 

 ihe late Spencer F. Balrd. 



The classification, numeration and nomenclature conform strictly with the Check 

 List of North American Birds recently published by the A. O. P. For ihe benefit of ob- 

 servers along our southern border, a s>nopsls of all Mexican. Cuban and Bahaman spe-

THE ANALYTICAL KEYS 

 Are unlike those previously used for any ornithological work in America, ana are mod- 

 els of conciseness and utility. Taken with the accurate outline cuts, giving the bills, 

 claws, etc., no one can fall to use them with absolute certainty of satisfactory results. 



Every genus has been worked up exactly :is If it were the subject of a special mono- 

 graph, based on all the material available, and not a single page, or part of a page, as 

 printed, has been previously published in anything like the same f >rm. 



Not only are the essential characters of every species and sub-species given, with 

 measurements, but the various plumage of each, depending on sex, age and season, are 

 carefully dlstlngulshel. The nest and eggs are concisely described. 



No active ornithologist, cologlst or sportsman can afford to be without this book, as 

 It will be the 



STANDARD AUTHORITY 

 on North American Birds for many years to come.
