Aylmeri jesses are considered safer in falconry because they reduce which risk?

• A. They are cheaper than other jesses
• B. They require less maintenance
• C. They reduce constriction risk
• D. They are stronger and less prone to breakage

Answer: (C)

The safety improvement here is about reducing constriction on the leg. Aylmeri jesses use a small ring worn on the bird’s leg (an anklet) with the jess threaded through that ring rather than forming a tight loop around the leg. Because the strap isn’t wrapped snugly around the limb, swelling, movement, or tension from a snag is less likely to cinch the strap tight against the flesh. The ring acts as a fixed anchor and keeps the jess from wrapping tightly around the leg, which lowers the risk of constriction and related injury. This safety feature is why they’re preferred for reducing constriction risk, rather than for being cheaper, easier to maintain, or inherently stronger.
