(d) The fourth edition of the Check-list gave common names for sub- 
species (e.g., Eastern Robin, Southern Robin, Northern Robin, etc.). These 
subspecies, based on differences evident in a series of study skins, usually 
cannot be distinguished in the field. Therefore, common names of subspecies 
are eliminated in the current Check-list; subspecies are designated by 
scientific names only. Now the name Robin refers to all geographical races 
of the species no matter where they are found. 
(e) Hyphens have been dropped except when two or more words form a 
single adjective preceding a noun. 
Following are corrections to the common names of birds recorded in
