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 handsome species lives on cold, Pacific coastlines. In the U.S., it mostly breeds on uninhabited coastal marshes and tundra in western Alaska, so there are no breeding data. Audubon’s climate model predicts a significant shift and reduction in winter climate space, with only 3% of the current winter range remaining stable by 2080. Most individuals currently winter on the rocky shores of the Aleutian Islands, but many may shift to spend the winter further north near their current breeding range. That may make the species’ irregular incursions to the West Coast—celebrated by birders—somewhat less frequent.
