The darker the color, the more favorable the climate conditions are for survival. The outlined areas represent approximate current range for each season. More on reading these maps.
This powerful Arctic falcon flourishes in mainly open terrain where large prey—especially ptarmigans and seabirds—abound. The Gyrfalcon disperses south a bit, but not much, in winter; winter sightings even in the northern tier of U.S. states are uncommon. Audubon’s climate model predicts considerable shifting of climate space for Gyrfalcons in the future, and less than half of the present range remains stable. Additionally, many of the Gyrfalcon’s favored prey species are forecast to decline in the same region. As is so often the case with climate change, the most severe effects may be the indirect ones.
