What is the primary purpose of an Aylmeri jess?

The primary purpose of an Aylmeri jess is to provide safety during flight. These jesses are specifically designed to attach the falcon to its falconer and allow for a level of secure restraint while still facilitating the bird's ability to fly freely. This safety feature is crucial as it enables the falconer to maintain control over the bird, preventing it from flying away while ensuring the bird can also maneuver effectively in the air.

While comfort, securing the tail bell, and enabling quick release may have their roles, they are secondary to the core function of ensuring the hawk’s safety during flight. The Aylmeri jess allows for a connection that balances freedom and safety, which is vital in the practice of falconry.
