What does 'impping' refer to in falconry?

Imping refers specifically to the practice of using a feather to replace a broken or damaged feather on a raptor. This technique involves attaching the new feather to the bird’s wing or tail, which is crucial for maintaining the bird's flying ability and overall health. Proper imping can help ensure that the bird retains its aerodynamic integrity, which is essential for effective hunting and flight. This process allows falconers to manage the feather condition of their birds, as damaged feathers can hinder a raptor's performance and well-being.

The other options pertain to different practices in falconry but do not capture the essence of imping as accurately. Training raptors in specific patterns is an aspect of training but is not related to feather care. Feeding raptors with live prey describes their nutritional needs rather than feather maintenance. Restoring raptors to a state of wildness is involved in the rehabilitation process and relates to the bird's behavior rather than addressing feather issues directly.
