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 Horned Grebe nests along the margins of lakes and ponds on the northern Great Plains and in the boreal forest of western Canada and Alaska. The species also occurs in the Old World, where it is called Slavonian Grebe. Still, the Horned Grebe may be in grave danger, as Audubon's climate model projects a 100 percent loss of current summer range by 2080. Even for a migratory species, that kind of loss will be too much to adapt to. Winter presents some potential gains, but it is hard to imagine these coming to fruition with such dramatic decline during the summer. This species winters at sea as well, where climate change is expected to influence other variables, such as the quality and availability of food.
