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.
Males of this species are raspberry-colored rather than purple. Females, with their bold facial pattern, resemble small female Rose-breasted Grosbeaks. Until the latter half of the 20th century, this was the only small reddish finch found in eastern North America. Audubon's climate model projects large northward shifts away from the current distribution in both summer and winter, but with only 11 percent of summer space and 41 percent of winter space remaining stable. Of particular note is the surge of suitable climate space in Alaska, where the species is not currently found.
