Falconry training and technique the jesses lying on the scale can change the reading, so the falconer has to be careful to lift them up while the bird is being weighed. Above that range of weight, the bird will be unresponsive in the field, lacking in motivation to hunt or return to the falconer in timely fashion. Gauntlets or gloves are used by the falconer to turn the arm into a suitable perching surface. Falconry gloves may only cover the fist and wrist, while gauntlets for larger species extend to the elbow. An eagle glove may cover the entire arm and a portion of
Falconry are kept for purposes of rehabilitation (for which a licence must still be held), and in such circumstances it may be possible for a competent falconer to teach a bird to hunt and kill wild quarry, as part of its regime of rehabilitation to good health and a fit state to be released into the wild. In New Zealand, falconry was formally legalised for one species only, the swamp/Australasian harrier ("Circus approximans") in 2011. This was only possible with over 25 years of effort from both Wingspan National Bird of Prey Centre and The Raptor Association of New Zealand (RANZ).
