VALEDICTORY 



This book, begun six years ago, has 

 greatly exceeded in number of pages the 

 original intentions of the author, but this 

 will not, he trust, prove disadvantageous 

 to the reader. 



As the title indicates, all the birds, 

 excepting perhaps a few very recently 

 described forms, which occur between the 

 North Pole and the Gulf of Mexico, east of 

 the Mississippi River, are given. As the 

 natural geographical western avifaunal 

 boundaries are the Great Plains, most of the 

 species which occur east of them are herein 

 included. 



In its scope as an exponent of field 

 characters it may be regarded as a com- 

 panion to my Directory to the Birds of 

 Eastern North America.
