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.
Nesting populations of this species have increased dramatically in the eastern portion of its summer range in recent decades, but the climate space for summering range is forecast to shift dramatically northward and contract for the future. Also, most of the world’s American White Pelicans winter in Mexico, and while Audubon's climate model predicts that the species’ winter range in the U.S. will be likely able to expand and shift northward, further research is needed for a better understanding of whether American White Pelicans may be able to adapt to the shifting available winter range or take advantage of the changing climate suitability for the species as a whole.
