The Accipitrinae are the subfamily of the Accipitridae often known as the "true" hawks, including all members of Accipiter and the closely related genera Erythrotriorchis , and Megatriorchis . The large and widespread genus Accipiter includes goshawks, sparrowhawks, the sharp-shinned hawk and others. They are primarily woodland birds that hunt by sudden dashes from a concealed perch, with long tails, broad wings and high visual acuity facilitating this lifestyle. In light of recent genetic research, the kites of the traditional subfamily Milvinae may also belong to this group.

Hawks, including the accipitrines, are believed to have vision several times sharper than humans, in part because of the great number of photoreceptor cells in their retinas (up to 1,000,000 per square mm, against 200,000 for humans), a very high number of nerves connecting the receptors to the brain, and an indented fovea, which magnifies the central portion of the visual field.

The genus level cladogram of the Accipitrinae shown below is based on a molecular phylogenetic study of the Accipitridae by Therese Catanach and collaborators that was published in 2024. [1] The number of species in each genus is based on the list maintained by Frank Gill, Pamela C. Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC). [2]

Micronisus – gabar goshawk

Urotriorchis – long-tailed hawk

Melierax – chanting goshawks (3 species)

Kaupifalco – lizard buzzard

Tachyspiza – goshawks, sparrowhawks (27 species, formerly in Accipiter)

Erythrotriorchis – goshawks (2 species)

Species in taxonomic order

Several genera or species formerly classified in this subfamily, such as Micronisus , Urotriorchis , Microspizias , and Circus , have since been moved out of Accipitrinae following phylogenetic studies. In contrast, other genera such as Lophospiza have since been reclassified into Accipitrinae. [3] [4]

Hawks and humans

Hawks are sometimes used in falconry, a sport in which trained birds of prey are flown at small game for sport.

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

<span class="mw-page-title-main">Accipitridae</span> Family of birds of prey

The Accipitridae is one of the three families within the order Accipitriformes, and is a family of small to large birds of prey with strongly hooked bills and variable morphology based on diet. They feed on a range of prey items from insects to medium-sized mammals, with a number feeding on carrion and a few feeding on fruit. The Accipitridae have a cosmopolitan distribution, being found on all the world's continents and a number of oceanic island groups. Some species are migratory. The family contains 255 species which are divided into 70 genera.

<i>Accipiter</i> Genus of birds

Accipiter is a genus of birds of prey in the family Accipitridae. With around 50 recognized species it is the most diverse genus in its family. Most species are called goshawks or sparrowhawks, although with the exception of the American goshawk almost all New World species are simply known as "hawks". They can be anatomically distinguished from their relatives by the lack of a procoracoid foramen. Two small and aberrant species usually placed here do possess a large procoracoid foramen and are also distinct as regards DNA sequence. They may warrant separation in the old genus Hieraspiza.

<span class="mw-page-title-main">Shikra</span> Species of bird

The shikra is a small bird of prey in the family Accipitridae found widely distributed in Asia and Africa where it is also called the little banded goshawk. The African forms may represent a separate species but have usually been considered as subspecies of the shikra. The shikra is very similar in appearance, as well as behavior, at least to some degree, to other Accipiter species including the Chinese goshawk, Eurasian goshawk and Eurasian sparrowhawk. They have a sharp two note call and have the typical flap and glide flight. Their calls are imitated by drongos and the common hawk-cuckoo resembles it in plumage.
