The Gyrfalcon - A Circumpolar Raptor
Their feathers give them an edge for nesting high in the Arctic

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 2500 years!

The Gyrfalcon - A Circumpolar Raptor
Written by Bob Sundstrom
This is BirdNote.
[Gyrfalcon calls, https://macaulaylibrary.org/asset/138146, 1.14-1.18]
Gyrfalcons are majestic birds. At two feet tall, they’re the largest of all falcons. And these powerful raptors can dive on prey at 130 miles per hour.

Gyrfalcons are circumpolar, nesting in the far north of Asia, North America, and Europe, including Iceland and Greenland. The Gyrfalcons that nest in northern Greenland are especially eye-catching -- their feathers are a bright, snowy white.

Gyrfalcons 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. Some spend the entire winter on frigid sea ice, hunting other birds. Others travel south during the coldest parts of the year, sometimes even into the northern United States.

Gyrfalcons reuse the same nesting site year after year. Some nests have been occupied for 2500 years! Imagine! That means that Gyrfalcons were feeding chicks at these nest sites when Sparta was just going to war with Athens.
