Mid-Winter Waterfowl Survey [MWS]
Description / purpose
Some geese and ducks are not adequately monitored during the spring and summer because they nest in areas not well covered by breeding population surveys. Abundance indices for these species are obtained from surveys on wintering areas. Most of these surveys are targeted at specific species or populations. A nationwide effort to survey all waterfowl is conducted annually in January. This, the Mid-winter Waterfowl Survey, provides information on population trends for some species, distribution on the wintering grounds, and habitat use. The Mid-Winter Waterfowl Survey is conducted cooperatively by the states and the U.S. Fish and Wildlife Service.
