What kind of animal behavior is defined as "fledging"?

Fledging refers specifically to the process by which a young bird develops enough feathers and strength to leave its nest and begins its life outside of parental care. This critical stage in a bird's life marks the transition from dependency on adult birds for food and protection to an independent existence where the young bird must find food and navigate the world on its own.

Understanding fledging is crucial in wildlife management and conservation, especially when dealing with breeding and nesting birds. It often involves recognizing the signs of bird maturation and the timing of when juvenile birds leave the nest, which can help in identifying appropriate measures to protect these young birds during this vulnerable phase. The other options reflect different life stages or behaviors that are not specific to the fledging process.
