What is a common specification for a perch in falconry facilities?

A common specification for a perch in falconry facilities is that it must have a nonslip surface. This feature is essential because it helps to prevent the bird from slipping while perched. A nonslip surface provides better stability and comfort for the bird, which is crucial during rest periods. It allows the raptors to maintain a firm grip, which is especially important when they are transitioning between movements or when they need to quickly take off.

This characteristic of a perch contributes to the overall welfare and safety of the birds, as it reduces the chances of injuries that could occur from slipping. While other specifications like being suitable for outdoor use or being padded could also be advantageous, the nonslip feature directly addresses the functional needs of the bird on the perch, making it a primary consideration in falconry practices.
