What does the term "to break in" refer to in falconry?

In the context of falconry, "to break in" specifically refers to the process of training a bird of prey to respond to the handler's commands and become accustomed to hunting and being flown. This involves various techniques that ensure the bird can successfully engage in falconry activities.

While the option regarding breaking through a kill's skin might seem relevant to hunting behaviors, it does not accurately capture the essence of "breaking in" as it pertains to the handler's training and the bird's adaptation to falconry. The correct interpretation ties directly into developing a working relationship where the bird learns to associate commands with actions, a vital part of establishing effective communication between the falconer and the bird.

Introducing a young bird to the wild and adjusting a harness are also important aspects of bird care and management in falconry, but they do not encompass the term's primary meaning related to the training process.
