Is the common dog-leash snap-swivel reliable for attaching the jesses of a hawk to its leash?

The common dog-leash snap-swivel is not reliable for attaching the jesses of a hawk to its leash due to several factors. These snap-swivels are typically designed for use with dogs, which have different movement patterns, strengths, and needs compared to hawks.

For falconry, jesses are crucial for controlling and securing birds of prey, and the attachment method must ensure the safety and security of the bird during both flight and handling. A snap-swivel may not provide a secure hold due to its design, which can lead to accidental release or failure under the strain of a bird in flight. Additionally, the material and strength of the snap-swivel often do not match the demands of a hawk's strength and agility.

Falconers typically prefer more specialized equipment that is specifically designed for birds of prey, ensuring that it can withstand the unique stresses involved with handling and training these birds. This focus on reliability preserves the welfare of the hawk and minimizes the risk of escape or injury. Therefore, the answer is that it is not reliable for this purpose.
