What is the primary use of a bewit?

The primary use of a bewit is indeed to attach bells to the bird's leg. This traditional device consists of a strap, usually made from leather or a similar material, that is used to secure bells, which serve multiple purposes in falconry. One of the key functions of the bells is to help the falconer monitor the bird's movements while it is flying or during training sessions. The sound of the bells provides auditory feedback, allowing the falconer to keep track of the bird's location and activities, which is particularly useful in open fields or during hunting.

While attaching bells is the main function of a bewit, it's important to note that the other options describe different aspects of falconry equipment. The training of a falcon, for example, is usually aided by various other tools and techniques, and while certain equipment may support the weight of the bird or secure it in place, these functions do not specifically pertain to the bewit.
