A harrier is a member of the genus Circus in the a bird of prey family Accipitridae. Harriers characteristically hunt by flying low over open ground, feeding on small mammals, reptiles, or birds. The young of the species are sometimes referred to as ring-tail harriers. They are distinctive with long wings, a long narrow tail, the slow and low flight over grasslands and skull peculiarities. The harriers are thought to have diversified with the expansion of grasslands and the emergence of C4 grasses about 6 to 8 million years ago during the Late Miocene and Pliocene. [1]

Taxonomy

The genus Circus was introduced by the French naturalist Bernard Germain de Lacépède in 1799. [2] The type species was subsequently designated as the western marsh harrier. [3] [4] Most harriers are placed in this genus. The word Circus comes from the Ancient Greek κρέξ (kréx) referring to a long legged bird, and is possibly ultimately derived from an onomatopoeia. [5] The name harrier is thought to have been derived either from Harrier (dog), or by a corruption of harrower , or directly from harry . [6]

The genera Circus has in the past been placed in the subfamily Circinae but molecular phylogenetic studies have shown that such a grouping is polyphyletic for Accipitrinae. [7] [8] The harrier-hawks in the genus Polyboroides are not closely related and are placed in their own subfamily Polyboroidinae [8]

Ring-tails

Ring-tail is an informal term used by birders for the juveniles and females of several harrier species when seen in the field and not identifiable to an exact species. [9] Ring-tail harriers include the juveniles and females of Montagu's harrier (Circus pygargus), hen harrier (Circus cyaneus), and pallid harrier (Circus macrourus).

Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates. In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species also scavenge and eat carrion.

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

The hen harrier is a bird of prey. It breeds in Eurasia. The term "hen harrier" refers to its former habit of preying on free-ranging fowl.

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

The northern harrier, also known as the marsh hawk or ring-tailed hawk, is a bird of prey. It breeds throughout the northern parts of the northern hemisphere in Canada and the northernmost USA.

<i>Accipiter</i> Genus of birds

Accipiter is a genus of birds of prey in the family Accipitridae. Most species are called sparrowhawks, but there are many sparrowhawks in other genera too, such as Tachyspiza.

<span class="mw-page-title-main">Buteoninae</span> Subfamily of birds

<span class="mw-page-title-main">Circaetinae</span> Subfamily of birds

Circaetinae is a subfamily of the family Accipitridae which contains a group of medium to large broad-winged birds of prey. The group is sometimes treated as tribe Circaetini. These birds mainly specialise in feeding on snakes and other reptiles, which is the reason most are referred to as "snake-eagles" or "serpent-eagles". The exceptions are the bateleur, a more generalised hunter, and the Philippine eagle, which preys on mammals and birds.

<span class="mw-page-title-main">Accipitrinae</span> Subfamily of birds

The Accipitrinae are the subfamily of the Accipitridae often known as the "true" hawks. The subfamily contains 73 species that are divided into 11 genera. It includes the genus Accipiter which formerly included many more species. The large genus was found to be non-monophyletic and was split into several new or resurrected genera. The birds in this subfamily 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.

Milvus is a genus of medium-sized birds of prey. The genus was erected by the French naturalist Bernard Germain de Lacépède in 1799 with the red kite as the type species. The name is the Latin word for the red kite.

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

The Réunion harrier, also known as Réunion marsh harrier, is a species of bird of prey belonging to the marsh harrier group of harriers. It is now found only on the Indian Ocean island of Réunion, although fossil material from Mauritius has been referred to this species. It is known locally as the papangue or pied jaune. The Malagasy harrier of Madagascar and the Comoro Islands was previously treated as a subspecies of this bird but is increasingly regarded as a separate species. The Réunion harrier appears to be declining in numbers and it is classed as an endangered species.

<i>Buteogallus</i> Genus of birds

Buteogallus is a genus of birds of prey in the family Accipitridae. All members of this genus are essentially neotropical, but the distribution of a single species extends slightly into the extreme southwestern United States. Many of the species are fond of large crustaceans and even patrol long stretches of shore or riverbank on foot where such prey abounds, but some have a rather different lifestyle. Unlike many other genera of raptor, some members are referred to as "hawks", and others as "eagles".

<span class="mw-page-title-main">Long-winged harrier</span> Species of bird

The long-winged harrier is a common bird of prey species endemic to South America. They are members of the family Accipitridae, under the genus Circus which encompasses other harrier species. Its range encompasses most of South America, in grassland and wetland all across the continent. The long-winged harrier is a carnivorous bird, and will feed on many different animals found in its habitat. Like owls and other harrier species, the long-winged harrier has a distinctive facial disc, which is used to triangulate the bird's hearing while it is hunting.

<span class="mw-page-title-main">Harpiinae</span> Subfamily of birds
