General Comments The Ross's Goose is a regular winter resident, in very small numbers, amid large flocks of Snow Geese near the northern half of the coast. Also, the species has an unusual proclivity of turning up far inland with very small numbers of other geese, often at small ponds and other unlikely places for a rare goose. Records of this winter visitor have been greatly increasing in the 2000's, both near the coast and inland, probably owing to a range-wide population increase, but also helped by more vigilant study of large flocks of Snow Geese.

Coastal Plain Winter resident. Rare to locally uncommon but increasing in winter -- regular at a few sites -- in the northeastern portion of the province, south to Pea Island, Lake Mattamuskeet, Pungo refuge, and central Washington; late Oct through late Feb. Casual south of Dare and Hyde, with only five records: Beaufort (Carteret), 17-23 Dec 1999; Southport (Brunswick), 5-12 Jan 2002; Veterans Park (New Hanover), 15-19 Dec 2014; Ocean Isle Beach (Brunswick), 24 Nov 2015; and Veterans Park, 15-18 Jan 2017. Away from the tidewater area, there are but three records: one at Garysburg (Northampton), 27 Dec 2001; one at River Park North in Greenville (Pitt), 27 Dec 2013 - 2 Jan 2014; and one in Cumberland on 19 Dec 2013. Peak counts: 21 at Pungo refuge on 11 Jan 2015; 17 at that refuge on 19 Jan 2014; 16 at that refuge on 10 Feb 2019.
Piedmont Winter visitor. Formerly casual; now rare but greatly increasing, with about 40 records. Scattered across most of the province, though more frequent in the western half of the province. Extreme dates -- 21 Oct to 21 Mar, plus one lingering to 1 May, and an out of season record on 3 Jun (2005). Peak counts: 5, eastern Alexander, 6 Dec 2015; 4, Mid-Pines Road south of Raleigh (Wake), 1 Jan 2017; 4, along Shopton Road (Mecklenburg), 30 Nov - 3 Dec 2017; 3, Southern Lake Norman CBC, 19 Dec 2010.
Mountains Winter visitor. Rare, but greatly increasing, in the southern counties, with about 36 records. All are from the southern counties, except for two records in Watauga. Dates range between 12 Nov and 2 Apr, plus a very late bird in Watauga from 30 Apr - 10 May 2014. Peak count: 5, Mills River Wastewater Treatment Plant (Henderson), 9 Nov 2017; 4, at a wastewater treatment plant along NC 191 (Henderson), 4 Dec 2016; 3 in Henderson in Nov - Dec 2007.
Finding Tips In the past few winters, the species has been seen, generally with Snow Geese, in fields near Pungo Lake (especially along Pat's Road) and Phelps Lake, and at a pond/fields where US 64 meets Beasley Road (Washington). Over the last few decades, most were picked out of Snow Goose flocks along NC 12 at Pea Island, but the white geese flocks are declining there. In any case, patience is the key to finding the species. Normally, you must be willing to examine hundreds to a thousand or more Snows to find a Ross's. Fortunately, Ross's is quite a bit smaller than a Snow Goose, and most tend to be immaculately white in plumage. The species is difficult to pick out when feeding in marsh grasses or resting on water; some are picked out in flight amid flocks of Snow Geese by their obviously smaller size. Farther inland, they turn up mainly at farm ponds and other small isolated lakes and ponds, and not at the larger lakes/reservoirs.
