62 Proceedings of the 



seen. These birds, probably onl^y a single pair seen on 

 the several occasions, very likely bred in the valley but 

 I found no nests to corroborate this conclusion. This 

 dvtck is known to breed locally in the sandhills. 



9. Nettion carolincnse (Gmelin) — Green-winged Teal. 



A flock of about a dozen were noted on the Loup, August 

 28, 1910, by M. H. Swenk. 



10. Querquedttia discors CLinnaeus) — Bkie-winged Teal. 



The Blue-winged Teal also nests in the sandhills of Ne- 

 braska and had I been near any lakes or ponds I would 

 probably have found breeding pairs of the birds, but the 

 only occasions I saw the species were August 30, 1911, and 

 May 17, 1912, a solitary bird in both cases, the first one 

 on the river, the second on a little brook emptying into 

 the larger stream. M. li. Swenk flushed several from 

 ponds and sloughs near Dunning, June 1, 1911, and R. H. 

 Wolcott noted it in June, 1906. 



11. Spatula clypeata (Linnaeus) — Shoveller. 



This duck is recorded by R. H. Wolcott as occuring dur- 

 ing June, 1906, and doubtfully in July, 1911. It is prob- 

 ably only a migrant at this point. 



12. Dafila acuta (Linnaeus) — Pintail. 



Pintails are recorded by F. M. Chapman as having been 

 seen on the river at the Reserve. The species did not 

 occur during my observations, which, however, took 

 place some time after the normal migration period of 

 these ducks. 



13. Marila affinis (Evton) — Lesser Bluebill. 



A pair of Lesser Bluebills was seen on the Dismal river 

 on May 26, 1912, but neither of the birds was noted on 

 any of the later excursions to that stream. Although 

 evidently mated, these were in all likelihood only migrat- 

 ing individuals. A small flock was noted on the Loup 

 by M. H. Swenk October 28, 1910. 



14. Botaurus lentiginosus (Montagu) — Bittern. 



The only time I saw the Bittern was on August 20, 1911, 

 on which date I flushed a single bird from the margin 

 of the river where it had been half concealed in the tall 

 grass. R. H. Wolcott records it in June, 1906, and July, 

 1908, and F. M. Chapman in May, 1906.
