Mid-winter Waterfowl Survey

Metadata Updated: May 11, 2018

The Mid-winter Waterfowl Survey is a nationwide effort to survey waterfowl in areas of major concentration on their wintering grounds and provide winter distribution and habitat affiliations. 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.Survey design and field procedures are determined by individual states. The Mid-winter Survey is, today, conducted primarily by fixed-wing aircraft, although some states use helicopters and/or conduct counts from automobile or boat in certain areas. The Mid-winter Survey is known as a “cruise” survey, in that specific predefined transects are not defined. Instead, an aerial crew determines the best and most practical means to conduct a complete count of all waterfowl within a predefined unit area. The exact means of coverage may vary from year to year; however, the objective is to obtain a complete count of all waterfowl within the survey unit. The survey is conducted annually and typically starts the first week of January. Cooperators then enter data into a data entry application and the data is sent directly to the respective Flyway office where an annual report is produced and data are stored.
