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 Yellow-billed Loon is the larger, pale-billed, tundra-nesting cousin of the Common Loon. Audubon's climate model projects a 64 percent loss of current winter range by 2080. The Canadian Arctic Archipelago, shown by the model to have suitable climate in the winter season, could become a regular wintering area in the future, as a species that migrates long distances and winters on the ocean (as this one does) should not have too much trouble wintering in new areas should that become necessary. Due to its remote breeding habitat, the model does not have enough data to construct projections regarding the future suitability of areas for its summer range.
