How long do young peregrines stay in the nest?
Approximately 6 weeks. The downy white feathers the nestlings have when they hatch are gradually replaced by juvenile feathers in about three to five weeks. At about 6 weeks of age, young falcons will make their first attempts at flying. After they fledge (take their first flight) they are referred to as fledglings and will be dependent on the adult falcons until they can hunt for themselves (about 4 weeks later).
