Why can narrow jess bracelets be dangerous?

Narrow jess bracelets can indeed lead to leg sores on birds of prey. When the jesses are too narrow, they can cause excessive friction or pressure against the bird's legs as it moves and interacts with its environment. This continuous rubbing can result in irritation, abrasions, or sores, which can become infected if not properly managed. Careful consideration of jess width, fit, and material is essential for the comfort and health of the bird, making it crucial to select jesses that are appropriately sized and constructed to prevent such health issues.

While the other options mention potential concerns for falconry equipment, they do not directly relate to the specific threat of leg sores caused by narrow jess bracelets. It's important for falconers to be aware of these risks to ensure the well-being of their birds during training and hunting activities.
