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.
You can play or pause the animation with the orange button in the lower left, or select an individual frame to study by clicking on its year.
This large, plump, and unwary finch is a favorite at winter feeders in Canada and the northern U.S. Audubon's climate model predicts that only 13 percent of the summer range will remain stable, and the total amount of appropriate summer climatespace is forecast to contract by 44 percent. Of particular concern is the population that nests in the mountains of the lower 48 states. As is the case with many high-altitude breeders, climate change is projected to cause a significant contraction of the Pine Grosbeak’s range. The winter range seems more (64 percent) stable, with only a small (15 percent) contraction. Pine Grosbeaks are also found across most of northern Eurasia.
