Fledging
Fledging is a hazardous time for young ospreys. From about 5 or 6 weeks old they will start exercising their wings perching on the edge of the nest, furiously flapping their wings and helicoptering above the nest for a few seconds.
The youngsters typically take their first flight when they are about 7 weeks old, leaving the nest for a short while before returning again. The young birds have to master flight and, just as important, learn how to land. They could face trouble if they are not able to return to the nest.
