Eeismatura rubida, (Wils.) Bp. 

 Buddy Duck. 



Rather common alonjij the Missouri during its migrations. One that I obtained 

 from Sarpy County, in October, 1874, had 31 locusts, 20 other insects, and some small 

 fresh-water mollusks in its stomach. 



There are still other ducks frequenting the waters of Nebraska, but as I have not 

 examined the contents of tbeir stomachs I will not enumerate them here. Evidently, 

 however, all the ducks will destroy more or less locusts and vast numbers of aquatic 

 insects.

Family LAEID^. 



Some members of this family I did not succeed in identifying, and they are therefore 

 left out of this list. The numbers present in Nebraska vary a great deal in different 

 years. 



Stercorarius pomatorhinus, (Temm.) Vieill. 



The Pomarine Jaeger. 



I only saw this bird alive once. It was on the Missouri, in Dakota County, in May, 

 1869. One that was shot on the Platte near Fremont in May, 1873, was sent to me to , 

 .be identified. It had a few grasshoppers and a mass of the remains of crawfish, frogs, 

 and a fish in its stomach. 



Larus marinus, Linn. 



Ch^eat Black-hacked Gull. 



I only saw this bird once in Nebraska, and then it was dead. Some Winnebago' In- 

 dians brought one to Dakota City in May, 1871. They had shot it on the Missouri.
