Mid-winter Surveys Complete

Since 1935, pilot-biologists have been flying the winter skies to count birds. Known as the Mid-winter Survey, this coordinated, federal-state survey of wintering waterfowl provides information about species distribution and abundance. For some species, particularly those that breed in inaccessible regions of the arctic, the Mid-winter Survey provides the primary annual index to species abundance and is used to guide the establishment of hunting regulations.
