Which of the following is essential falconry equipment in the field?

In falconry, the lure is an essential piece of equipment in the field because it plays a crucial role in training and recalling birds of prey. The lure, typically made of leather and filled with some type of edible material, serves as a method for attracting the falcon back to the handler after it has been flown free. This is particularly important during training sessions and when encouraging the bird to return from flight.

While bells and jesses are also important equipment in falconry, they each serve different purposes. Bells help in locating the bird when it is in flight, especially in areas where visibility is poor. Jesses are used to secure the bird to the falconer’s glove and allow for controlled movement. Although these items are vital for safety and communication, the lure is unique in its direct application for hunting and recalling the bird, making it particularly indispensable in the field. Thus, the option stating the lure is essential accurately emphasizes its primary role in falconry practice.
