True or false: The common dog-leash snap-swivel is reliable for attaching jesses to a leash.

The correct answer is that using a common dog-leash snap-swivel for attaching jesses to a leash is false because these snaps are not designed with the specific safety and reliability needs of falconry in mind. Falconry involves working with birds of prey that can exert significant force and may perform unexpected movements. Snap-swivels typically associated with dog leashes may not hold securely under such conditions, risking the bird's control or safety.

In falconry, it is vital to use specialized equipment that is engineered for the specific weight and behavior of birds of prey. Reliable attachments like those designed specifically for jesses ensure that the connections are secure and durable, resisting failure during use. This is crucial for both the falconer’s safety and the well-being of the bird.
