About Waterfowl Populations Over Time

Migration Station’s “Waterfowl Populations Over Time” application is an interactive view which takes a combination of data collected by the United States Fish and Wildlife Service (USFWS) from the the Breeding Population and Habitat Surveys and their Mid-Winter Waterfowl Surveys.

The Mid-Winter Waterfowl Survey is a nationwide effort organized by the United States Fish and Wildlife Service (USFWS) to survey wintering waterfowl populations to assess the size of wintering waterfowl populations and the characteristics of their migrations. 

The Breeding Population and Habitat Survey is an aerial survey during the late spring to assess the potential breeding population size of over 20 waterfowl species, their liklihood for brood success due to climate conditions, and the estimates of fall flight populations.
