What is the implication of a hawk being described as sharp-set?

A hawk being described as sharp-set indicates that it is in a state of hunger, which puts it in a heightened readiness and alertness for hunting. This term reflects a physical condition where the bird may appear leaner due to having not eaten recently, thus intensifying its drive to seek food. It emphasizes the hawk's instinctive behavior to hunt when food is required for its energy and survival.

In the context of falconry, recognizing this behavior is critical, as it signifies that the hawk is motivated to engage in hunting activities. Understanding this physical state helps falconers determine the right time to take their hawk out for hunting, ensuring effective training and success in capturing prey.

The other options imply conditions that do not correspond with the term "sharp-set" – being tired, well-fed, or injured presents a different set of behaviors and responses that are not conducive to the hunting readiness that being sharp-set suggests.
