General Comments The Canvasback has experienced continental population declines for several decades. It was formerly a locally common to very common winter resident to bays/sounds and coastal and Tidewater impoundments in the state; our highest counts were in the 1970's. Fortunately, the species is still locally numerous, but flocks number mostly in the hundreds now. The species is found in wide open waters of shallow bays as well as the larger lakes and impoundments.

Coastal Plain Winter resident; declining. Uncommon to locally common, mainly along the northern coast and Tidewater area, south to the lower Neuse River; rare to locally uncommon along the southern coast. Rare to locally uncommon inland. Mainly late Oct to early Apr. Peak counts:
Piedmont Winter visitor/resident; declining. Rare to locally uncommon, most numerous along the eastern edge of the province. Mostly mid-Nov to late Mar. Peak counts: 1,300 to maybe 3,000, Roanoke Rapids Lake, 27 Dec 2008; 300, Lake Benson (Wake), 25 Nov 1966; 300, Brier Creek Reservoir (Wake), 15 Feb 2009.
Mountains Very rare winter visitor, with only about 7 records, all from the southern mountains (Buncombe, Haywood, Henderson, Transylvania). Dates range from 24 Nov to 18 Feb. Peak count: 4, WTP along NC 191 (Henderson), 29 Dec 2013. Considering that it is hardly rare in the rest of the state, and considering the many records for Redhead in the mountains, this species is mysteriously scarce in the province.
Finding Tips This species can be somewhat difficult to find in many areas. It is usually easily found, particularly from mid-Nov to mid-Jan, from the Lake Mattamuskeet causeway. Other good sites are the Swan Quarter ferry, North Pond at Pea Island, and the lower Cape Fear River.
