The Brant is a small, dark sea-goose that winters almost exclusively in coastal estuaries and bays where eelgrass grows. It migrates in low, winding flocks along coastlines rather than the classic V-formation of Canada Geese. When eelgrass beds were devastated by wasting disease in the 1930s, Atlantic Brant populations collapsed by over 85%.
