By 2080, this great icon of the north will have only 25 percent of its non-breeding season range and 44 percent of its breeding range remaining, according to Audubon’s climate models. In both seasons the potential to shift northwards in a warming climate is significant. While the bird may be able to keep pace with the rapidly changing world, it looks all but certain that Minnesota will lose its iconic loons in summer by the end of the century.
Each map is a visual guide to where a particular bird species may find the climate conditions it needs to survive in the future. We call this the bird’s “climatic range.”
The colors indicate the season in which the bird may find suitable conditions— blue for winter, yellow for summer (breeding), and green for where they overlap (indicating their presence year-round).
The darker the shaded area, the more likely it is the bird species will find suitable climate conditions to survive there.
The outline of the approximate current range for each season remains fixed in each frame, allowing you to compare how the range will expand, contract, or shift in the future.
The first frame of the animation shows where the bird can find a suitable climate today (based on data from 2000). The next three frames predict where this bird’s suitable climate may shift in the future—one frame each for 2020, 2050, and 2080.
