The Birds of Wyoming. 39 



169. Chen hyperborea (Pall.). 

 Lesser Snow Goose. 

 Migratory ; rare. Grinnell reports having seen a flock 

 of these birds on the Yellowstone river near the lake, 1875. 

 Bond has taken a few at Cheyenne. I have seen several flocks 

 of white geese about Hutton's lakes which I anticipate were 

 of this species ; but since none were killed the record is ques- 

 tioned. 



171a. Anser albifrous gambeli ( Hartl. ). 

 American White-fronted Goose. 

 Accidental ; very rare. Bond reports this species as fol- 

 lows : "I have mounted a fresh specimen which was said to 

 have been killed at the Cheyenne lakes." 



172. Branta canadensis (Linn.). 

 Canada Goose. 

 Summer resident ; rather common. During migration 

 thev are rather abundant about lakes, and often remain until 

 the 1st of December. Dr. Tesurun has found them nesting 

 in dead trees along the North Platte river near Douglas. The 

 nests were usually from 18 to 25 feet from the ground. They 

 also breed about the lower mountain lakes. I have seen sev- 

 eral flocks of this species at the head of Green river and along 

 the Snake river about the middle of August and have also 

 seen several broods just large enough to fly near the mouth of 

 the Grand Canon of the North Platte. Williston found them 

 breeding at Lake Como, and remarks: "Nest was found in 

 marsh May 2, built up securely with weeds and sticks about 

 18 inches above the water, eggs fresh." Grinnell reports them 

 numerous on Yellowstone lake in 1875. Drexel found them at 

 Fort Bridger, 1858. Jesurun reports them common at Doug- 

 las and Bond at Cheyenne. Coues reports the Canada goose 

 from Yellowstone river and Sweetwater river. 



172 a. Branta canadensis hutchinsii (Rich.). 

 Hutchin's Goose. 

 Migratory. I am inclined to believe that this species is
