Appendix B. Subspecies 



Because the potential exists tor one or more of the subspecies listeci in this appendix to be 

 elevated to species status m the future, detailed observation reports of these birds are requested. 

 Information on specific locatK)n, habitat, and breeding habits is especially helpful, and may be 

 particularh- xaluable for subseciucnt editions. The species know n previoush' as the Solitary Vireo is an 

 example. Since the last edition the Solitary Vireo was split into three species: Plumbeous Vireo, Cassin's 

 \'ireo, and Blue-headed Vireo, each of which appears in this edition. 



*(Note: we elected to continue to include maps in this edidon for the Solitary Vireo and Northern 

 Oriole (now Bullock's Oriole and Baltimore Oriole), because the database contains important historic 

 information on the distribution of these previously named species). 



Where information is a\'ailable, distribution maps are presented for the subspecies listed in this 

 appendix. These maps are included to encourage bird watchers to submit future records at this 

 taxtinomic le\el. Although nt) maps appear for Eurasian Green-winged Teal, White-winged and 

 Grav-headed subspecies of the Dark-eyed Junco, and Gray-crowned and Gray-headed (Hepburn's) 

 forms of the Grav-crowned Rosy-Finch because of current lack of data, they may be included m future 

 editions of this publication.
