ADDENDUM 



The Fourth Edition of the Check-List of North American Birds, pre- 

 pared by a committee of the American Ornithologists' Union and pub- 

 lished in 1 93 1, was used as one of the basic references in preparation of 

 the ornithological check-list of this book. 



Subsequent to the time when the manuscript was submitted to the 

 printer, the Fifth Edition of the A. O. U. Check-List appeared. Some of 

 the changes occurring in this edition have been incorporated within the 

 body of this book. Other essential changes could not be made feasibly, 

 so these changes are indicated in this section. Entries, as they occur in 

 this book, are listed alphabetically in the left-hand column. Changes 

 present in the Fifth Edition of the A. O. U. Check-List are given in the 

 right-hand column.
