Summary
Description
Complete estimates of waterfowl populations in each of 164 management units through the fortyeight coterminous United States were systematically developed for May 1965 and each month from August 1965 through April 1966. Estimates were made for all duck species except sea ducks, mergansers, Florida, mottled, and Mexican ducks; for all species of geese, except Rosss geese; and for American coots.
