Description

Falconry was once called "hawking" and any bird used for falconry could be referred to as a hawk.

Aristotle listed eleven types of ἱέρακες (hierakes, hawks, singular ἱέραξ hierax): aisalōn (merlin), asterias, hypotriorchēs, kirkos, leios, perkos, phassophonos, phrynologos, pternis, spizias, and triorchēs. Pliny numbered sixteen kinds of hawks, but named only aigithos, epileios, kenchrēïs (kestrel), kybindis, and triorchēs (buzzard)

Falconry is the hunting of wild animals in their 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 flies a hawk or an eagle. In modern falconry, the red-tailed hawk, the Harris's hawk, and the peregrine falcon 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 February 2005, Canadian ornithologist Louis Lefebvre announced a method of measuring avian "IQ" by measuring their innovation in feeding habits. Based on this scale, hawks were named among the most intelligent birds.

Hawks have four types of colour receptors in the eye. These give hawks the ability to perceive not only the visible range but also the ultraviolet part of the spectrum. Other adaptations allow for the detection of polarised light or magnetic fields. This is due to the large number of photoreceptors in the retina (up to 1,000,000 per square mm in Buteo, compared to 200,000 in humans), a high number of nerves connecting these receptors to the brain, and an indented fovea, which magnifies the central portion of the visual field.
