What does "to fly at mark" mean for a hawk?

The phrase "to fly at mark" specifically refers to a hawk perching above the location where it has spotted its quarry. This behavior signifies that the bird has a target in mind and is prepared to pursue it from its vantage point. By flying at mark, the hawk remains alert and ready to take action, either by diving down to capture its prey or by observing the movements of the animal below. This strategy increases the bird’s success rate during hunting by allowing it to utilize its excellent vision and reflexes effectively.

The other options focus on different aspects of hunting or flying that do not accurately describe the specific action represented by "to fly at mark." For instance, hunting in a specific area or soaring at high altitudes encompasses broader behaviors, while transitioning from a perch to the ground is a more generic action that does not convey the hunting strategy implied by the term. Understanding this distinction helps falconers effectively communicate and apply techniques in the field.
