The darker the color, the more favorable the climate conditions are for survival. The outlined areas represent approximate current range for each season. More on reading these maps.
The national symbol of the United States is projected to have only 26 percent of its current summer range remaining by 2080, according to Audubon’s climate model. However, it could potentially recover 73 percent of summer range in new areas opened up by a shifting climate. Its success isn’t guaranteed in the new areas—the majestic raptor will still have to find suitable food and nesting habitat.

The country’s most iconic bird is found throughout most of the United States and Canada, and locally south into Mexico. It dines primarily on fish, but will also feed on birds and mammals, and often eats carrion. Highly territorial during the breeding season, it is sociable the rest of the year, often gathering at communal roosting or feeding spots. The raptor has complex migration patterns; some are residents, while immature birds may roam nomadically for years, and adults breeding in the northern interior migrate far south for the winter. Bald Eagles experienced widespread population declines in the 20th century, largely as a result of pesticides and hunting. It rebounded after DDT was outlawed, and the Bald Eagle was removed from the Endangered Species List in 2007.
