Each map is an animated guide to where a particular bird species may find the climate conditions it needs to survive in three future time periods (2020, 2050, and 2080). We call this the bird’s “climatic range.”

The shaded areas indicate where the bird may find suitable climate conditions for each time period. They are color-coded by season: blue for winter, yellow for summer (breeding season), and green for where they overlap (indicating the bird’s presence year-round). The darker the shaded area, the more likely it is the bird will find suitable climate conditions in that area. 

The first frame of the animation shows where the bird can find a suitable climate today (based on data from 2000). 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 map above shows the projected range of the Common Loon. By 2080, the call of the loon may disappear from Minnesota in the summer as its breeding range moves north. Its winter range is even more heavily affected, declining 62 percent by 2050.
