 the following localities: Sundance, Sheridan, Buffalo, Otto, 

 Bonanza, near Casper and on the Laramie plains. There are 

 five skins in the University collection that have been taken in 

 Albany and Carbon counties. 



614. Tachycineta bicolor (Vieill.). 



Tree Swallow. 

 Summer resident ; not common. Locally they seem to be 

 plentiful, but are very particular in selecting a breeding place. 

 Drexel reported this species from Fort Bridger in 1858; Bond 

 has taken a few at Cheyenne; Cary has observed them near 

 Newcastle. I have found them breeding on the Little Laramie 

 river, 20 miles west of Laramie, and along Medicine Lodge 

 creek in Big Horn county. 



615. Tachycineta thalassina (Swains.). 



Violet-green Swallow. 



Summer resident and abundant in desirable localities. 

 They arrive on the Laramie plains about the ist of May and 

 by the 15th they are seen in great numbers in the vicinity
