From this it is apparent that the center of black duck dis- 
tribution on the wintering grounds in the Atlantic Flyway is in the 
coastal region bounded on the north by Long Island and on the south 
by North Carolina. 
Long Island should be considered an integral part of the 
Middle Atlantic region because diverse migration routes converge there 
and because it has similar ecological conditions. The winter population 
remaining in New England is but a minor portion of the Atlantic Flyway 
population, the bulk of which occurs in the Middle Atlantic States. 
The trend from year to year of the Long Island and New England 
population does not always follow the trend of the entire Atlantic Flyway 
black-duck population (fig. 7). If the northeastern states were delin- 
eated as a separate region for regulation purposes, and their relatively 
small wintering black-duck population given primary consideration, there 
would be years in which a low mid-winter count in this region would ne- 
Cessitate unwarranted restrictions on the northeastern gunner. The black 
ducks of the Northern Atlantic States are actually closely associated 
with black duck populations farther south. The percentage of the north-— 
eastern black-duck population remaining along coastal New England during 
the winter is apparently not a constant one and may be influenced by 
climatic conditions and other factors.
