By 2041–2070, rock ptarmigan suitable area falls about 36% on average, while water pipit range is nearly stable.

Key findings

Mean contractions of 35.7% (ptarmigan), 26.1% (accentor), and 24.5% (snowfinch); water pipit +2.1%; temperature was the top predictor; UKESM gave the harshest losses.

Methodology

Fitted MaxEnt models for four Alpine birds using citizen-science records from seven countries, then projected 2041–2070 climates from four GCMs under SSP585.

Limitations

Does not track actual dispersal, hunting, or land-abandonment, and a worst-case SSP585 is not a prediction of policy.
