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.
Striped flashily with black and white above and glowing-flame orange below, a male Blackburnian Warbler engenders surprise and awe in all who see it for the first time, and it remains a perennial favorite of even jaded birders. Like many other warblers, this species depends on coniferous (especially spruce) forest to breed in. Audubon’s climate model projects a nearly total shift in summer climate space for this species, so it will likely need to adapt to new regions well north of the current breeding areas. Most Blackburnian Warblers winter in South America, some as far south as the Bolivian Andes, making this one of the most southerly migratory warbler species.
