LOCAL LISTS 



Local List No. 1. 

 FROM WESTERN WYOMING. 



BY ELIOT BLACK-WELDER. 



The observations on which the following list is based were 

 made in the course of two geological expeditions in the western 

 part of the Rocky Mountains. In a good many cases identifications 

 are more or less uncertain, as indicated by the question marks 

 after the names. This arises from the fact that no specimens were 

 collected and in only a. few cases were birds shot for identification. 

 On the other hand, a very strong Zeiss field glass (12 power) was 

 used to great advantage, and this permitted the recognition of many 

 species which with the unaided eye would have remained uncertain.
