GREAT BLACK-BACKED GULL

Larus marinus

Status: Rare casual spring and fall migrant statewide. Rare casual summer and winter visitor Keith and Lincoln Cos.

Documentation: Photograph: 20 Jan-18 Mar 1996, first basic Lake McConaughy , Keith Co (Brogie 1997).

Taxonomy:  No subspecies are recognized.

Changes since 2000: There are no Nebraska records prior to 1988; this species is expanding its North American range, including its first breeding on the Great Lakes in 1954 (Olsen and Larsson 2004). Nebraska observations have increased accordingly; of about 40 records in all (as of Jan 2016), 30 have occurred since 2000.

Spring: Although this species is almost regular in occurrence, we cite all records. Only four of the spring records are of adults. There are 16 accepted records of birds which were not present in winter:

12-17 Feb 2015 first cycle Branched Oak Lake, Lancaster Co (Silcock 2015a)

3 Apr 1996 adult Wagontrain Lake, Lancaster Co (Grzybowski 1996)

5 Apr 2014 first cycle N.P. Dodge Park, Omaha (Silcock 2014b).

Summer: There are two reports from Lake McConaughy of birds which apparently remained for some time. A first basic first noted 20 Jan-18 Mar 1996 (Brogie 1997), was likely the same bird seen there in first alternate 4 Aug 1996 (Brogie 1997), in second basic 15-17 Feb 1997 (Grzybowski 1996), and as a “third year” 12-13 Apr 1997 (not accepted by NOURC, Brogie 1998). Another first cycle bird appeared at Lake McConaughy 19 Jan 2004 (Brogie 2005), and was likely the same bird seen there as a first alternate 15-16 May and 19-20 Jun 2004 (Silcock 2004a, 2004b).

Fall: The earliest seven reports, through 31 Oct, are of adults, whereas nine of the other 10 are of immatures. There are 17 records:

19 Dec 2004 first cycle Lake McConaughy (Silcock 2005a)

31 Dec 2005-2 Jan 2006 second basic Lake McConaughy (Silcock 2006a).

Winter: The six accepted records, including five immatures, are from either Sutherland Reservoir or Lake McConaughy. This species tends to return to or remain at favored winter localities; the 1988 and 1989 records are probably the same individual, as may be a first basic bird at Lake McConaughy 20 Jan-18 Mar 1996, 4 Aug 1996, and 15-17 Feb 1997 (see Summer). The adult at Lake McConaughy 16 Feb 2008 may have been the same adult that was there 14 Sep 2007 (see above).

3-31 Jan 2009 Lake McConaughy (Silcock 2009a)

14 Jan 1989 immature Sutherland Reservoir (Grenon 1990)
