Differential Distribution of Wintering Brant by Necklace Type

Abraham et al. (1983) demonstrated that positive assortative mating by necklace type, the white feather pattern around the neck, occurs among Brant (Branta bernicla hrota ) breeding at East Bay, Southampton Island, N.W.T. They also suggested that differential distribution of Brant by necklace type a...

Description
Summary:Abraham et al. (1983) demonstrated that positive assortative mating by necklace type, the white feather pattern around the neck, occurs among Brant (Branta bernicla hrota ) breeding at East Bay, Southampton Island, N.W.T. They also suggested that differential distribution of Brant by necklace type also may occur on the wintering grounds. The authors tested the "differential distribution" hypothesis by collecting Brant on three major wintering areas along the Atlantic Coast: 1) Nassau County, Long Island, New York; 2) Cape May County, New Jersey; and 3) Chincoteague National Wildlife Refuge and near Folley Creek, Accomac County, Virginia. Brant were shot in bays and estuaries in the three locations, except for 18 birds that were cannon-netted on golf courses on Long Island. Collections were made during a 2-week period in late January 1984 so that Brant movements among the three locations were minimal.
