What are jesses used for in falconry?

Jesses serve a critical function in falconry, as they are straps typically made of leather or other durable material that are attached to the legs of a raptor. Their primary purpose is to securely attach the bird to its perch or leash, ensuring that the falconer has control over the bird when it is not in flight. This connection helps prevent the bird from flying away or escaping when it is being managed outside of its natural environment. Additionally, jesses allow for safe handling of the bird during training sessions or health checks, as they provide a reliable means of restraint.

While immobilizing a bird for training, measuring weight, and assisting with feeding are important aspects of falconry practice, they are not the main function of jesses. The design and use of jesses prioritize the safety and control of the raptor in conjunction with the falconer's practices.
