The American Ornithologists’ Union 
CHECK-LIST OF NOBTH AMERICAN BIRDS, 
Second Edition, 1895, Thoroughly Revised. 
The preface to this work defines its scope and object and includes selections from 
the A. O. U. Code of Nomenclature, of special importance in the present connection. 
The table of contents consists of a systematic list of orders, sub-orders and families of 
North American birds. The check-list proper gives the scientific and common name, 
number in previous list, and geographical distribution of the 1,068 species and sub- 
species, constituting the North American Avifauna. This is followed by a list of birds 
of doubtful status, and a list of the fossil birds of North America. 
This new edition has been carefully revised; the recent changes in nomenclature 
and species and sub-species described since the publication of the first edition in 1886 
are included, while the portion relating to geographical distribution has been much 
amplified.
