What type of peg may be involved in impinging a Red-tailed Hawk?

Imping is a technique used in falconry to repair a bird's feathers, especially when they are damaged. The type of peg involved in this process is known as an imping peg. An imping peg serves as a support that holds the new feather in place while it affixes itself to the bird. This is essential for ensuring the feather's alignment and stability as the hawk molts or grows in new feathers.

In contrast, other types of pegs mentioned, like glue pegs, are generally not utilized in the imping process because they typically involve adhesive methods that are not suitable for feather restoration on birds of prey. Coping pegs also do not relate to imping, as they are more aligned with trimming or shaping a bird's beak and talons rather than feather care. Therefore, imping pegs are specific to the practice of feather repair in falconry, making them the correct choice for this question.
