What is meant by 'hack' in falconry?

In falconry, the term "hack" refers to the temporary release of a raptor for training purposes. This practice allows a falconer to condition and train a bird in a controlled environment, where the bird can learn to hunt and seek food. The primary goal during this phase is to develop the bird's instinctual hunting skills while still allowing it the freedom to return to the falconer's presence.

This method benefits both the bird and the falconer, as it provides the raptor with real hunting experiences without completely removing it from the falconer's care and training regimen. Proper management during hacking ensures the bird becomes acclimated to its environment while still learning important skills that will aid in successful hunting when fully trained.

The other choices refer to different concepts in falconry. Permanent release is not in line with hacking since it implies a final decision rather than a training tactic. Capturing a wild raptor involves a completely different set of skills and considerations and isn't related to training. Feeding a raptor, while essential for care, does not encapsulate the training aspect that hacking represents.
