Melanitta deglandi. White-winged Scoter. Rare transient. Nine specimens from Douglas and Leavenworth counties, taken from 1927 to 1938; several sight records from eastern Kansas.
Subspecies in Kansas: M. d. deglandi (Bonaparte).
Melanitta perspicillata (Linnaeus). Surf Scoter. Rare transient. Eight known specimens (three of which are now in University of Kansas collection), all taken in autumn, seven in Douglas County, one in Sedgwick County; several sight records from eastern Kansas.
No subspecies recognized.
Oidemia nigra. Common Scoter. Accidental. The two preserved specimens from Kansas supposedly of this species are actually Surf Scoters. L. B. Carson, however, identified an adult male Common Scoter killed by a hunter at Horton Lake, Brown County, in the early 1930's. Others have been seen by reliable field observers. Every effort should be made to secure specimens from Kansas.
Subspecies in Kansas: O. n. americana Swainson, on geographical grounds.
* Oxyura jamaicensis. Ruddy Duck. Common transient throughout state, rare winter resident. One breeding record: Frank Robl saw an adult female with one small young at Cheyenne Bottoms, Barton County, in approximately 1929.
Subspecies in Kansas: O. j. rubida (Wilson).
Lophodytes cucullatus (Linnaeus). Hooded Merganser. Uncommon transient and winter resident throughout state. Probably nests occasionally (two specimens at KU taken in east in June), but no proof of this available.
No subspecies recognized.
