What can happen to a bird if jess bracelets are too narrow?

When jess bracelets are too narrow, they can create excessive pressure on a bird's legs. This constriction can lead to irritation and injury, resulting in leg sores. The material of the jess can rub against the skin, especially as the bird moves, which could damage the sensitive skin around the legs. Providing proper sizing is crucial to ensure the bird remains comfortable and to prevent any health issues related to circulation or skin integrity.

Choosing appropriate jess sizes helps prevent complications like sores, allowing the bird to maintain its natural behavior and well-being while in the care of a falconer. This highlights the importance of proper equipment in the practice of falconry, where the health and safety of the bird are paramount.
