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 handsome Red-throated Loon breeds on Arctic tundra and winters on large bodies of water (mostly at sea). Audubon's climate model projects significant shifts during both seasons, but of particular concern is that only just over one-third of the current summer climate space will remain stable by 2080. The small amount of potential new summer space in the high arctic is likely already being used by the species, so this species may experience more pressure than currently projected. Available winter area is projected to increase significantly; in particular, the model projects a large increase in winter suitability for the Great Lakes, which will presumably remain increasingly ice-free as the planet warms.
