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 colorful species is common in the pine forests of western North America. Audubon's climate model projects a 70 percent loss of current summer range by 2080. Part of the area to be vacated is a section of central and eastern Canada, identified by the model as having suitable climate, but not currently occupied by the species. Taking this out of the equation, the loss of breeding area would be less severe. Predicting the Western Tanager’s future is also complicated by potential interbreeding and competition with the closely related Scarlet Tanager. By 2080, the model shows that the two may broadly overlap in range.
