A falconry bird is taught to do its job by the falconer and is rewarded with food. All of these birds must be kept at a certain weight while being flown, known to falconers as flying weight, this is when the bird is hungry enough to respond to the falconer but not so hungry that the bird is starving. If the bird is not at flying weight when flown, the bird is usually not interested and if it gets away from the falconer, is usually lost. Falconers fly falcons, buteos, accipiters, owls, and eagles, all of which are flown by people with different experience. For example, a begginer is advised not to fly accipiters, most owls and falcons, or eagles. So buteos are usually looked upon as the ideal 'begginers' birds by most falconers. Although they are called 'begginer's' birds even the most experienced falconers fly them. The Harris Hawk is one of the most commonly used birds in present falconry.  All birds used in falconry catch different quarry or 'prey'. Some small birds such as kestrels rarely take any game at all, while others, such as a female Red-tail will be able to bring down rabbits and pheasants. Falconry birds also require a lot of equipment. Scales, hawking bags, leashes, jesses, anklets, bells, hoods, the glove, swivels, lures, creance, and perches are all vital equipments to falconers. The birds also require a weathering or a place to stay and sleep. Falconers take extremeley good care of their birds and many times put the birds needs ahead of their own. U.S. falconers have to pass a written exam and have their hawk's living quarters checked before they can become legal falconers. They must also undergo an apprenticeship. As far as preparing for the written exam, the Arizona Falconers Association's website has an online test to test your knowledge.
