The Gyrfalcon – A Circumpolar Raptor

Gyrfalcons are circumpolar, nesting in the far north of Asia, North America, and Europe, including Iceland and Greenland. They evolved as a distinct species in the Pleistocene Era, around 100,000 years ago. Their large size and warm feathering gave them an edge for nesting high in the Arctic. Gyrfalcons reuse the same nesting site year after year, and some nests have been occupied for 2,500 years!
