What does 'hacking' a raptor achieve?

Hacking a raptor refers to a training method where a captive bird is allowed to fly free in a controlled environment before being fully trained for hunting and falconry. This practice is aimed at developing the bird's physical fitness, specifically its lungs and muscles. By allowing the bird to fly freely, it engages its muscles and enhances its cardiovascular health, which is crucial for hunting and sustained flight.

This method not only prepares the raptor for its role in the field but also helps the bird become more acclimated to its environment. The physical activity associated with flying improves overall strength and endurance, which are essential traits for a successful hunter.

While other practices may influence a raptor's behavior or physical state, hacking is fundamentally about developing the natural abilities of the bird through increased physical activity and exposure, making option B the most accurate in describing the outcome of this training method.
