raised " green heads " saying that the migrants that come in the fall are a 

 much finer race of birds and easily recognizable by their superior size. 



16.* Chaulelasmus streperus. Gadwall. — An adult and brood of 

 newly hatched young seen and four of the latter collected between Camps 4 

 and 5, July 9. Dippie found it common on Buffalo Lake in 1896 and 

 Horsbrough reports nests in 1914. 



17.* Mareca americana. Baldpate. — At least two pairs observed 

 on Brock's Lake near Camp 1, and a male collected, June 28. Horsbrough 

 noted it near Alix and records nests at Buffalo Lake. 



18.* Nettion carolinense. Green- winged Teal. — Common and 

 with young on some of the smallest sloughs on the prairie level but not 

 often seen on the river itself. The only specimens obtained were flying 

 juveniles at Camp 11, August 15 and 23 where Young reported them as not 

 common. 



19.* Querquedula discors. Blue-winged Teal. — Common on the 

 lakes and sloughs on the prairie level but not seen often in the river valley. 

 Specimens taken at Camps 1 and 11 August 24. 



20.* Spatula clypeata. Shoveller. — Only seen at Camp 11 on 

 the Little Sandhill Creek, August 17 and 18 when specimens were taken. 



21.* Dafila acuta. Pintail. — This species did not seem to be very 

 common. A female was seen swimming in the river between Tolman 

 Ferry and Drumheller and acted as if it had young nearby. Young saw 

 one large flock near the Little Sandhill Creek and took specimens of juvenile 

 birds August 3 and 4. We have another specimen taken by Horsbrough 

 at Buffalo Lake, May 1915, who records nests at Buffalo Lake and vicinity. 



22.* Marila marila. Greater Scaup. — Though we did not specifi- 

 cally identify Greater Scaups we have one taken by Horsbrough, October 

 1915, at Alix, who reports nests at Buffalo Lake. 



23.* Marila afiinis. Lesser Scaup. — Numbers of Scaups were seen 

 on the ponds on the prairie level near Camp 1 and near Nevis. Most 

 seen were males. The few females seen acted as if they had nests nearby 

 but none were found. Our only specimen was taken at Camp 1 and is of 

 this species. The Lesser Scaup is not mentioned by Horsbrough. 



24.* Marila valisineria. Canvas-back. — Two downy young in our 

 collections taken by Horsbrough June 1914 at Buffalo Lake, who records 

 several nests. 



25.* Clangula clangula. American Golden-eye. — The commonest 

 duck on the upper river but not seen below Tolman's Ferry. The absence 

 of the Golden-eye on the lower river is probably due to the lack of large 

 timber supplying nesting holes. Most of the birds seen were females and it 

 seems probable that the sexes separate before reproductive duties are fin- 

 ished. We surmise that the males might be found in numbers on the larger 

 lakes in the vicinity. None were seen closely enough to detect Barrow's 

 Golden-eye, though they were looked for carefully, and Horsbrough does 

 not mention it. Our only adult specimen is a female and an undoubted 

 American Golden-eye. Several broods of young were met with on the
