Jesses

Jesses are slender straps fitted to the legs of raptors used in falconry to restrain and control the bird when it is not in flight. They form part of the standard equipment for handling, training, and housing. In typical setups, one jess is worn on each leg and is secured to a leather anklet around the bird’s tarsus. The free end of the jess bears a ring, stud, or clip to which a leash or creance can be attached, allowing the handler to guide or restrain the bird as needed.

Materials and construction: Traditional jesses are crafted from leather—often cowhide, goatskin, or kangaroo hide—but synthetic options are common. They are narrow and lightweight to minimize hindrance, with sizes chosen to fit the individual bird. Some designs include safety features such as quick-release mechanisms or breakaway components to reduce injury risk if the bird becomes snagged.

Fit and maintenance: A proper fit is snug but not constrictive, enabling adequate blood flow and wing movement. Jesses should be inspected regularly for wear, cracking, or rough edges and replaced when compromised. They are cleaned and dried after use and removed when the bird is unrestrained under supervision.

Regulatory context: Falconry is typically regulated, and jesses are part of standard compliance. Laws and club rules often specify permitted materials, sizing, and training requirements, with welfare guidelines guiding their use.
