Big Brains and Big Ranges Might Not Save Birds from Climate Change

April 22, 2025 • by Marc Airhart

Global bird sightings from citizen scientists and a view into “climate niches” reveal unexpected risks for some birds.

Two birds perched on branches. The left bird has sleek brownish-gray feathers, a black eye mask, a crest on its head, and yellow-red wing markings. The right bird features speckled brown-gray plumage with bright yellow wing patches and a reddish-brown head.

Four panels illustrating bird species geographic ranges and climate conditions.

(a) The breeding range for the Bohemian waxwing (purple) extends over a large swath of the Arctic, while the chestnut-crowned laughingthrush (red) inhabits a much smaller arc in Asia centered on Nepal and Bhutan. (d) Yet the waxwing inhabits a much smaller and more extreme range of climate conditions than the laughingthrush, suggesting the waxwing may be at greater risk from climate change than previously thought.
