There are also some raptor representations in the northern Altai, western Mongolia.Frederick II of Hohenstaufen (1194–1250) is generally acknowledged as the most significant wellspring of traditional falconry knowledge.
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 and most significant challenges to Aristotle's often flawed explanations of nature.
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 "hawking" 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.
