How long can a peregrine falcon stay in the cold?

Peregrine falcons are well-adapted to cold environments and can tolerate freezing temperatures for extended periods. They possess a layer of insulating feathers and a unique blood circulation system that helps maintain body heat. While they can endure cold weather, their ability to hunt and find food may be more limited in severe conditions, affecting how long they can remain active in the cold. Generally, they can survive in cold climates as long as they have access to food.
