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 Common Goldeneye is, like the closely related Bufflehead, exclusively a cavity nester, so it’s no surprise that this species breeds only in wooded places. It’s apparent that—along with the boreal forest—the Common Goldeneye may face a potentially strong shift in climate space as is forecast by Audubon’s climate model. In summer, 39% of the current core range will remain stable by 2080, and a large decline in the boreal forest could be devastating for the species. The species’ winter prospects are similar to most other ducks’: a fair shift in range and an increase in potential areas with suitable climate conditions.
