PREFACE. 
Tuts volume has been written to fill a place hitherto vacant 
in ornithological literature. The works of Wilson,! Audubon,? 
and Nuttall,3 are costly, and rarely offered for sale, having 
been in a great measure superseded by modern authors. The 
recent and most complete work on American Ornithology.t that 
of Messrs. Baird, Brewer, and Ridgway, is also costly. Mr. 
Samuels’ book on the ‘Birds of New England and Adjacent 
States”> has been thought too expensive to be within the reach 
-of all, and more or less inaccurate and incomplete. Dr. Coues’ 
admirable ‘‘ Key to North American Birds,”® which is probably 
the best book of reference for collectors, and students of inani- 
mate birds, treats merely of structure, classification, and spe- 
cific descriptions. The same author's * Field Ornithology.”* 
and Mr. Maynard’s *‘Naturalist’s Guide,”® have also been
