LIST OF BIRDS OF CHEYENNE AND VICINITY. 



By Fkank Bond. 



Cheyenne; is located in the midst of the Great Plains resion, a 

 little over 6000 feet above the ocean, with an annual rainfall of 

 thirteen inches. The plains around Cheyenne are drained b}' streams 

 fringed by cottonwoods and willows Avhicli attract the migrants. 

 One of these streams flows through the city, whicli by persistent 

 arboriculture has been made an immense grove of trees, an oasis in 

 the desert. Five small lakes, from within the city limits to a mile 

 and a half bc3'ond, offer resting places to waterfowl of all descrip- 

 tions. Tlie mountain range twenty miles west of the city, acting 

 as a barrier to flight, completes the conditions which give Cheyenne 

 a peculiar and diversifled avifaima. The list covers a radius of about 

 three miles from the eily limits
