What is a common description of the young bird in the brancher stage?

In the brancher stage, a young bird is characterized by having left the nest but still depending on its parents for food and guidance. This stage occurs after the initial fledging phase, where the bird has developed enough to leave the confines of the nest and may be experimenting with short flights and exploring its surroundings. Even though it is mobile and can perch on branches, it continues to rely on adult birds for nourishment and learning essential survival skills such as hunting and foraging.

The other stages described in the options refer to different developmental phases. A bird that has just hatched is in the nestling stage, while a bird still in the nest has not yet experienced its first flight and is still learning to fly. Similarly, a bird that is learning to hunt on its own would be in a later stage of development, having gained some independence from its parents.
