Sharp-shinned hawk, a small member of the Accipitrinae subfamily

Hawks are birds of prey of the family Accipitridae. They are very widely distributed and are found on all continents except Antarctica.[1]

The terms accipitrine hawk and buteonine hawk are used to distinguish between the types in regions where hawk applies to both. The term "true hawk" is sometimes used for the accipitrine hawks in regions where buzzard is preferred for the buteonine hawks.

All these groups are members of the family

Accipitrid that is not an eagle.[3]

The common names of some birds include the term "hawk", reflecting traditional usage rather than taxonomy. For example, some people may call an

History

Falconry was once called "hawking" and any bird used for falconry could be referred to as a hawk.[4]

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).[5]

Groups

Accipiter group

The accipitrine hawks generally hunt birds as their primary prey. They are also called "hen-hawks", or "wood-hawks" because of their woodland habitat.

The

Megatriorchis (Doria's goshawk). Melierax
(chanting goshawks) may be included in the subfamily, or given a subfamily of its own.

Erythrotriorchis (the red and chestnut-shouldered goshawks) is traditionally included in Accipitridae, but is possibly a convergent genus from an unrelated group (see red goshawk taxonomy).

Buteo group

The "Buteo group" includes genera Buteo, Parabuteo, Geranoetus, and most of Leucopternis. Members of this group have also been called "hawk-buzzards".[6]

Proposed new genera

Rupornis, and Pseudastur are formed from members of Buteo and Leucopternis.[7]

The "Buteogallus group" are also called hawks, with the exception of the solitary eagles. Buteo is the type genus of the subfamily Buteoninae. Traditionally this subfamily also includes eagles and sea-eagles. Lerner and Mindell (2005) proposed placing those into separate subfamilies (Aquilinae, Haliaaetinae), leaving only the buteonine hawks/buzzards in Buteoninae.

IQ" by measuring their innovation in feeding habits.[8]
Based on this scale, hawks were named among the most intelligent birds. The hawk is very intelligent towards humans and other hawks.[9]

Eyesight

Hawks, like most birds, are

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.[12][13][14] Hawks additionally have two foveae (depressions in the retina with high photoreceptor density) in each eye, one centrally-placed, and the other temporally-placed.[15]

Migration

Like most birds, the hawk migrates in the autumn and the spring. Different types of hawks choose separate times in each season to migrate. The autumn migrating season begins in August and ends mid-December. It has been studied that there are longer migration distances than others. The long-distance travelers tend to begin in early autumn while the short distance travelers start much later. Thus, the longer the distance the earlier the bird begins its journey. There have been studies on the speed and efficiency of the bird's migration that show that it is better for a hawk to arrive at its destination as early as possible.[16] This is because the first bird that arrives has the first pick of mates, living area, food, and survival necessities. The more fat a bird has when it starts its migration, the better chance it has of making the trip safely. Kerlinger states that studies have shown that a bird has more body fat when it begins its migration, before it leaves, than when has arrived at its destination.[17]

One of the most important parts of the hawk's migration is the flight direction because the direction or path the bird chooses to take could greatly affect its migration. The force of wind is a variable because it could either throw the bird off course or push it in the right direction, depending on the direction of the wind.[17] To ensure a safer journey, a hawk tries to avoid any large bodies of water in the spring and fall by detouring around a lake or flying along a border.[18]

Hawkwatching is a citizen scientist activity that monitors hawk migration and provides data to the scientific community.

Habitat and distribution

The red-tailed hawk is probably the most common hawk in North America.[19] Past observations have indicated that while hawks can easily adapt to any surrounding, hawks prefer a habitat that is open. Hawks usually like to live in places like deserts and fields, likely as it is easier to find prey. As they are able to live anywhere, they can be found in mountainous plains and tropical, moist areas. Hawks have been found in places such as Central America, the West Indies, and Jamaica.

Behavior

Starting in the hawk's early life, it is fed by its parents until it leaves the nest.

predator, some are gentle and quiet.[citation needed] When it flies, the hawk flaps its wings rapidly, and then uses that momentum to glide smoothly and gracefully through the air.[18]

The idea of flocking during migration has been closely analyzed, and it has been concluded that it is a commutative tool used by birds and other animals to increase survival. It has become clear to observers that a hawk traveling in a flock has a greater chance of survival than if it travelled alone. Another word used in the United States that has the same meaning as "flock", particularly in terms of groups of hawks, is "kettle".[17]: 215–16 

Reproduction

Hawks are known for their unique

reproduce is different from most. The male and female will fly together in a circular motion. Once they reach a certain height, the male will dive toward the female and then they will raise back to the height again. The two birds will repeat this until finally the male latches onto the female and they begin to free-fall down to earth. In one year, a female hawk will lay about five eggs. Both the male and the female will cater and take care of the eggs for about a month until they hatch.[20] The male and the female create their nest before the mating season and improve it together during the nesting season. The two birds usually make their nest prior to mating. Some species of hawks tend to be monogamous and stay with the same mating partner their whole lives.[18]

In culture

A war hawk, or simply hawk, is a term used in politics for somebody favoring war. The term reportedly originated during the 1810 debates in Congress over a possible war with Great Britain when Congressman John Randolph called the pro-war faction led by Henry Clay, the 'war-hawks'.[21]

Numerous sporting clubs, such as the

Hawthorn Hawks and the Malmö Redhawks
, use the bird as an emblem. Miami University in Oxford, Ohio officially became known as the RedHawks in 1997 after formerly being known as the Redskins.

Hawks are highly associated with Guru Gobind Singh in the Sikh community. According to ornithologists, he is believed to have kept a white Northern Goshawk. This is reflected in that the Northern Goshawk was made the official state bird of Punjab, India.[22][23][24][25]
