470 ZOOLOGY— BIRDS. 



when undisturbed in and out of the rushes, and showing in their close 

 fellowship the utmost good will to each other and the other occupants 

 of their watery domain. They very quickly learned that certain demon- 

 strations made by our party boded no good to themselves, and, quietly 

 betaking themselves to the middle of the pond, they there swam about, 

 viewing us with the utmost unconcern, always, however, taking good care 

 that the interval between us should exceed by a little the range of our shot- 

 guns. The lakes and ponds of Utah are sometimes in the fall fairly covered 

 Avith the Coots that swarm in from their northern summer resorts, make 

 a brief stay of one or two days, and then with renewed strength stretch 

 their wings for the south. I think they always migrate by night.

Immense numbers of this goose were noticed at Rush Lake, Utah, in 

 early November. They throng through the Territory during the fall months, 

 retiring farther south only as the lakes become covered with ice. Accord- 

 ing to Dr. Coues, they winter in great numbers in Arizona along the Colo- 

 rado ; and, from all I could learn, I judged that the Upper Rio Grande in 

 Colorado also attracted large numbers at this season.
