Falconry is the hunting of wild quarry in its natural state and habitat by means of a trained bird of prey. There are two traditional terms used to describe a person involved in falconry: a falconer flies a falcon; an austringer (German origin) flies a hawk (Accipiter and some buteos and similar) or an eagle (Aquila or similar). In modern falconry, the red-tailed hawk (Buteo jamaicensis), the Harris's hawk (Parabuteo unicinctus), and the peregrine falcon (Falco perigrinus) are some of the more commonly used birds of prey. The practice of hunting with a conditioned falconry bird is also called "hawking" or "gamehawking", although the words "" and "hawker" have become used so much to refer to petty traveling traders, that the terms "falconer" and "falconry" now apply to most use of trained birds of prey to catch game. Many contemporary practitioners still use these words in their original meaning, however.
In early English falconry literature, the word "falcon" referred to a female falcon only, while the word "hawk" or "hawke" referred to a female hawk. A male hawk or falcon was referred to as a "tiercel" (sometimes spelled "tercel") as it was roughly one third less than the female in size.
Evidence suggests that the art of falconry may have begun in Mesopotamia, with the earliest accounts dating to approximately 2,000 BC. There are also some raptor representations in the northern Altai, western Mongolia. The falcon was a symbolic bird of ancient Mongol tribes. There is some disagreement about whether such early accounts document the practice of falconry (from The Epic of Gilgamesh and others) or are misinterpreted depictions of humans with birds of prey. During the Turkic Period of Central Asia (7th century AD), concrete figures of falconer on horseback were described on the rocks in Kyrgyz. Falconry was probably introduced to Europe around AD 400, when the Huns and Alans invaded from the East.Frederick II of Hohenstaufen (1194–1250) is generally acknowledged as the most significant wellspring of traditional falconry knowledge. He is believed to have obtained firsthand knowledge of Arabic falconry during wars in the region (between June 1228 – June 1229). He obtained a copy of Moamyn's manual on falconry and had it translated into Latin by Theodore of Antioch. Frederick II himself made corrections to the translation in 1241 resulting in De Scientia Venandi per Aves. King Frederick II is most recognized for his falconry treatise, De arte venandi cum avibus ("The Art of Hunting with Birds"). Written himself toward the end of his life, it is widely accepted as the first comprehensive book of falconry, but also notable in its contributions to ornithology and zoology. De arte venandi cum avibus incorporated a diversity of scholarly traditions from east to west, and is one of the earliest challenges to Aristotle's explanations of nature.
