What does the phrase "rake away" signify in falconry?

The phrase "rake away" in falconry actually refers to abandoning a hunt or the act of pulling back from an ongoing pursuit. This is a specific term used by falconers to indicate that the bird has been commanded or has chosen to disengage from the hunting scenario, whether due to lack of prey, distraction, or other reasons.

The other options do not accurately reflect the meaning of "rake away": flying at low altitude is a distinct behavior and does not imply abandonment, catching prey in flight pertains to a successful hunt rather than disengagement, and "none of the above" suggests that there is no correct interpretation among the given choices, which is not the case here since "abandon a hunt" accurately captures the meaning of the phrase. Thus, the answer aligns with the terminology used in falconry to describe a specific action taken during hunting.
