WHITE-WINGED SCOTER

Melanitta fusca deglandi

Status:  Rare casual spring migrant statewide. Rare regular fall migrant statewide. Rare casual winter visitor.

Documentation: Specimen: SUI 18764, 14 Oct 1903 Crystal Lake, South Sioux City, Dakota Co.

Taxonomy: There are three subspecies currently recognized (for example, Clements et al 2016): M. f. fusca, Velvet (European) Scoter, M. f. stejnegeri, Asiatic White-winged Scoter, and M. f. deglandi American White-winged Scoter. Some authors (Gill and Donsker 2017, Sangster et al 2005), treat these as two species, Velvet Scoter M. fusca, and White-winged Scoter M. deglandi, the latter with two subspecies, M. d. stejnegeri of central and eastern Siberia, and M. d. deglandi of Alaska and northern Canada. It has further been suggested that all three taxa deserve species status (Garner et al 2004). Nebraska birds are presumed deglandi.

SpringMar 25, 26, 26 <<<>>> Apr 30, May 1, 4

This scoter appears much more often in spring than the others, with 28 reports. There are earlier dates than those above: 14 Feb 1916 Clay Co (cited above), 24 Feb 2002 Holmes Lake, Lincoln, Lancaster Co, 4-9 Mar 2007 Gavin’s Point Dam, Cedar Co, 10-17 Mar 2012 Lake Ogallala, Keith Co, 14 Mar 1981 Washington Co, and 19 Mar 2007 Lakes North and Babcock, Platte Co.

Fall:  Oct 15, 16, 17 <<<>>> Dec 19, 19 ,20

There is an earlier report 7-20 Oct 1965 Adams Co, and several later reports: one was on the DeSoto NWR CBC 23 Dec 2007, first winter birds were at Lake McConaughy, Keith Co 31 Dec 2004, a juvenile male was at Lake McConaughy 31 Dec 2011, a female was there 31 Dec 2016-1 Jan 2017, a single was at Gavin’s Point Dam 3-8 Jan 2005, one at Lake Ogallala 29 Dec 2016-8 Jan 2017, and 1-2, including an adult female and a juvenile male were at Lake Ogallala 1-8 Jan 2011. In addition to these reports is a specimen taken 18 Dec 1900 near Kearney (HMM 2531; Brooking, Notes).

White-winged Scoters are far more common in Nebraska than the other scoter species in fall as well as in spring. Since the 1990s, colonization of Lake Michigan by zebra mussels (Dreissena polymorpha) has caused a significant increase in use of the lake by this species (Baldassarre 2014).

  • High counts: 10 in Lancaster Co 2 Nov 1986, 7 in Lancaster Co 18-31 Oct 1984, and 7 at Summit Lake, Burt Co 12 Nov 2017.

WinterThere are three mid-winter records, and one of over-wintering. Two, a male and a female, wintered at Lake Ogallala 2015-2016.  Tout (1947) saw a flock of seven on the North Platte River near North Platte 14 Jan 1926. A single bird was at Lake Ogallala 13 Jan-28 May 1985 (Rosche 1994); the date of its final occurrence has been incorrectly reported as 25-28 Jun 1985 (Loren and Babs Padelford, pers. comm., Cortelyou 1985). One was at Gavin’s Point Dam 11 Jan 2009.

There is a relatively small wintering population on the Great Lakes (Baldassarre 2014).
