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 Eurasian Wigeon is an Old World species that is currently a rare but regular winter visitor along the Pacific Coast of Canada, Washington, Oregon, and northern California. Audubon's climate model projects that over half of the winter range will shift and that the total amount of climatically suitable area for wintering will sligntly decrease by 2080, both of concern. Projections for breeding range are not reported by the model because the species does not breed in North America.
