These are mainly woodland birds with long tails and high visual acuity, hunting by sudden dashes from a concealed perch.
- More generally (especially in North America) to mean small to medium-sized members of (often) the Falconidae, Pandionidae (the Osprey) and the Accipitridae - the family which includes the "true hawks" (Accipiters) as well as eagles, kites, harriers and buzzards. The falcons and caracaras are around 60 Species of diurnal birds of prey that comprise the family Falconidae. The Osprey (Pandion haliaetus, also called Sea Hawk, is a diurnal, fish-eating Bird of prey. The Accipitridae is one of the two major families within the order Falconiformes (the diurnal birds of prey) The genus Accipiter is a group of birds of prey in the family Accipitridae, mostly consisting of birds known as Goshawks and Sparrowhawks Eagles are large birds of prey which are members of the Bird order Falconiformes and family Accipitridae, and belong to several genera Kites are raptors with long wings and weak legs which spend a great deal of time soaring A Harrier is any of several species of diurnal birds of prey which fly low over meadows and marshes and hunt or harry small animals or birds (hence their common Buteo ( Etymology: Buteo is the Latin name of the Common Buzzard) is a Genus of medium-sized wide-ranging raptors

The common names of birds in various parts of the world often use hawk in the second sense. For example, the Osprey or "fish hawk"; or, in North America, the various Buteo species (e. g. , the Red-tailed Hawk, B. The Red-tailed Hawk ( Buteo jamaicensis) is a medium-sized Bird of prey, one of three species colloquially known in the United States as the " jamaicensis).
In February 2005, Canadian ornithologist Louis Lefebvre announced a method of measuring avian "IQ" in terms of their innovation in feeding habits. Country to "Dominion of Canada" or "Canadian Federation" or anything else please read the Talk Page Ornithology (from Greek ὄρνις ὄρνιθος ornis, ornithos, "bird" and λόγος logos, "knowledge" is the branch of An Intelligence Quotient or IQ is a score derived from one of several different Standardized tests attempting to measure Intelligence. [1] Hawks were named among the most intelligent birds based on his scale.
Hawks are widely reputed to have visual acuity several times that of a normal human being. This is due to the many photoreceptors in the retina (up to 1,000,000 per square mm for Buteo, against 200,000 for humans), an exceptional number of nerves connecting these receptors to the brain, and an indented fovea, which magnifies the central portion of the visual field. Photoreceptor can refer to In anatomy/cell biology Photoreceptor cell: a photosensitive cell most commonly referring to a specialized type of neuron The vertebrate retina is a light sensitive part inside the inner layer of the Eye. Neurons (ˈnjuːɹɒn also known as neurones and nerve cells) are responsive cells in the Nervous system that process and transmit information The brain is the center of the Nervous system in animals All Vertebrates and the majority of Invertebrates have a brain The fovea, also known as the fovea centralis, is a part of the Eye, located in the center of the Macula region of the Retina. The term visual field is sometimes used as a Synonym to Field of view, though they do not designate the same thing
