What does the term "call off" refer to in falconry?

The term "call off" in falconry refers to the process of attracting a hawk by using a specific voice command or signal. This technique is essential for falconers who need to regain their bird's attention or encourage it to return after it has been distracted or has flown away. The effectiveness of this command relies on the bond between the falconer and the hawk, as well as the training that the bird has undergone to respond to vocal cues or signals from its handler.

In this context, the other options do not accurately represent the term "call off." For instance, training a hawk to fly away implies teaching it to leave, which is contrary to the purpose of calling it back. Releasing a hawk from captivity or setting it free in the wild both involve letting the bird go, whereas "call off" is about bringing the bird back to the handler's presence rather than releasing it. Understanding these nuances is vital for effective falconry practice and communication with the hawk.
