Specimen: 3.2 km W Prospect, female, November 5, 1935. The 

 Bufflehead is an uncommon and irregular winter resident. Gabriel- 

 son and Jewett (1940) give September 20 (Lake County) for their 

 earliest Oregon date and May 15 (Tillamook County) for their latest 

 date. Buffleheads have been recorded between those dates at Gardner 

 Reservoir, Hoover's Lakes, and at the Game Ponds. They should 

 also be expected at Willow Creek, Hyatt, and Howard Prairie res- 

 ervoirs, and other mountain bodies of water. 



Oxyura jamaicensis. Ruddy Duck. 



Specimen: Ashland, male, April 23, 1960. The Ruddy Duck is 

 a common winter resident from November to March, occurring 

 wherever there is open water. During December at least one in- 

 dividual may be found on almost every body of water north of Med- 

 ford as far as the Rogue River. Of 13 Medford CBCs, this species 

 has been recorded on 10 at an average of 49 individuals per count. 



Lophodytes cucullatus. Hooded Merganser. 



This species is an uncommon late winter resident and spring 

 migrant. Latest, April 5, Shady Cove. This merganser probably occurs

 the Rogue River below Prospect; it is less common on the Lower

This merganser is a rare winter visitor. Two females and a male 

 were observed on the Game Ponds on November 22, 1964, where one

 and Jewett (1940) consider the species a casual inland winter visitor 

 on the basis of late nineteenth century records.
