Branta bernicla hrota, B. b. nigricans
Status: Rare casual spring and fall migrant statewide.
Documentation: specimen: nigricans, HMM 2557, 10 Nov 1916 Phillips, Hamilton Co; photograph: hrota, 29 Oct 2017, Burt Co.
Taxonomy: Taxonomy has been controversial, especially in North America, where 3-4 distinct breeding populations occur that are not easily assigned to current subspecies concepts. A conservative position is taken by most authorities, who recognize three subspecies, one in Eurasia (bernicla) and two in North America, hrota and nigricans (Lewis et al 2020, Gill et al 2020, Clements et al 2019). Lewis et al (2020) describe four “stocks” of Brant breeding in North America, each of which has separate ranges; some of these stocks may at some point be elevated to species status.
The subspecies and associated stocks are: hrota, including two stocks, one (“Atlantic Brant”) breeding in eastern North American mid- and low Arctic, wintering on the US Atlantic coast, and the other (“Eastern High Arctic Brant”) breeding on Canadian High Arctic Islands and wintering in Ireland, and nigricans, also including two stocks, one (“Black Brant”) breeding in the Canadian Low Arctic and northwestern Alaska, wintering on the Pacific Coast from Alaska to Mexico, and the other (“Gray-bellied” or “Western High Arctic Brant”) breeding on the Parry Islands in the High Arctic of western Canada and wintering at Puget Sound on the Pacific Coast. Genetically and geographically, Gray-bellied Brant may be intermediate between hrota and nigricans (Lewis et al 2020).
Spring: There are six documented records as well as eight additional reports that fit the pattern of the documented reports. All are in the period 2 Feb-22 Apr, and include two documented reports of nigricans, both possibly referable to the same individual. See Comments.
