If a trained bird "carries," what does it do?

When a trained bird "carries," it refers to the behavior of the bird flying away with its catch after successfully capturing prey. This is a crucial aspect of falconry as it showcases the bird's skill in hunting and its ability to provide food for itself or the falconer. In many cases, a bird in this context might carry its prey to a designated location where it can be safely consumed. This behavior is essential for demonstrating the effectiveness and training of the bird, highlighting its instinctual hunting capabilities.

The other options, while related to a trained bird's interactions with the falconer, do not accurately describe the action of "carrying." Returning to the falconer, circling above them, or staying perched on the falconer's arm all describe different behaviors that signify different interactions and stages of the hunt but do not capture the essence of what it means for a bird to "carry."
