Approximate distribution of the genus Cathartes. Green indicates that at least one species is resident year-round and yellow shows areas where one species, the turkey vulture, is a summer-only breeding visitor.

The genus Cathartes includes medium-sized to large carrion-feeding birds in the New World vulture (Cathartidae) family. The three extant species currently classified in this genus occur widely in the Americas. There is one extinct species known from the Quaternary of Cuba. [3]

Contents

Cathartes is the Greek word καθαρτής, for "purifier," referring to these vultures' role as "cleansers" that "tidy up" decomposing corpses in nature.

Taxonomy

Description

The first member of this genus to be formally described, the turkey vulture, was named by Linnaeus as Vultur aura in his Systema Naturae in 1758, [4] but was eventually moved to the current genus which had been created by German zoologist Johann Illiger in 1811. [5] The yellow-headed birds first described in 1845 by John Cassin were not split into two species until 1964. [6] [7]

Systematics

Cathartes is one of the five genera of New World vultures. The taxonomic placement of these vultures remains unclear. [8] It is the only genus in its family that is not monotypic. The New World and Old World vultures are similar in appearance and have similar ecological roles, but evolved from different ancestors in widely separated parts of the world. The relationships between the two vulture groups is a matter of debate, with some earlier authorities suggesting that the New World vultures are more closely related to storks. [9]

In 2007 the American Ornithologists' Union's North American checklist moved Cathartidae back into the lead position in Falconiformes, but with an asterisk that indicates it is a taxon "that is probably misplaced in the current phylogenetic listing but for which data indicating proper placement are not yet available". [10] The AOU's draft South American checklist places the Cathartidae in their own order, Cathartiformes. [11] However, recent DNA study on the evolutionary relationships between bird groups also suggests that they are related to the other birds of prey and should be part of a new order Accipitriformes instead, [12] a position adopted in 2010 by the AOU's North American check-list, [13] and shared with the International Ornithological Congress. [14]

Species

The genus Cathartes has three recognized extant species: [15] [3]

One extinct species, Emslie's vulture (C. emsliei) is known from Late Quaternary fossil remains from Cuba, and it likely went extinct following the extinction of the megafauna whose carrion it would have fed on during the Quaternary extinction event, coupled with the subsequent loss of the savanna habitats it would have favored. [19]

Description

All Cathartes species have featherless heads with brightly colored skin, yellow to orange in the yellow-headed vultures, bright red in the turkey vulture. All three species share a well-developed sense of smell, which is rare in birds, that enables them to locate carrion under the canopy.

Distribution and habitat

The vultures of Cathartes mosty occupy forests of the Americas, especially Mexico, Central America, and South America.

Ecology and behaviour

While all species obtain most of their diet by scavenging, the lesser yellow-headed vulture is known to hunt live prey in wetland environments.

<span class="mw-page-title-main">New World vulture</span> Family of birds

Cathartidae, known commonly as New World vultures or condors, are a family of birds of prey consisting of seven extant species in five genera. It includes five extant vultures and two extant condors found in warm and temperate areas of the Americas. They are known as "New World" vultures to distinguish them from Old World vultures, with which the Cathartidae does not form a single clade despite the two being similar in appearance and behavior as a result of convergent evolution.

<span class="mw-page-title-main">Turkey vulture</span> Most widespread New World vulture

The turkey vulture is the most widespread of the New World vultures. One of three species in the genus Cathartes of the family Cathartidae, the turkey vulture ranges from southern Canada to the southernmost tip of South America. It inhabits a variety of open and semi-open areas, including subtropical forests, shrublands, pastures, and deserts.

<span class="mw-page-title-main">Black vulture</span> New World vulture

The black vulture, also known as the American black vulture, Mexican vulture, zopilote, urubu, or gallinazo, is a bird in the New World vulture family whose range extends from the southeastern United States to Perú, Central Chile and Uruguay in South America. Although a common and widespread species, it has a somewhat more restricted distribution than its compatriot, the turkey vulture, which breeds well into Canada and all the way south to Tierra del Fuego. It is the only extant member of the genus Coragyps, which is in the family Cathartidae. Despite the similar name and appearance, this species is unrelated to the Eurasian black vulture, an Old World vulture, of the family Accipitridae. For ease of locating animal corpses, black vultures tend to inhabit relatively open areas with scattered trees, such as chaparral, in addition to subtropical forested areas and parts of the Brazilian pantanal.

The king vulture is a large bird found in Central and South America. It is a member of the New World vulture family Cathartidae. This vulture lives predominantly in tropical lowland forests stretching from southern Mexico to northern Argentina. It is the only surviving member of the genus Sarcoramphus, although fossil members are known.

<i>Gyps</i> Genus of birds

Gyps is a genus of Old World vultures that was proposed by Marie Jules César Savigny in 1809. Its members are sometimes known as griffon vultures. Gyps vultures have a slim head, a long slender neck with downy feathers, and a ruff around the neck formed by long buoyant feathers. The crown of their big beaks is a little compressed, and their big dark nostrils are set transverse to the beak. They have six or seven wing feathers, of which the first is the shortest and the fourth the longest.

The lesser yellow-headed vulture also known as the savannah vulture, is a species of bird in the New World vulture family Cathartidae. It was considered to be the same species as the greater yellow-headed vulture until they were split in 1964. It is found in Mexico, Central America, and South America in seasonally wet or flooded lowland grassland, swamps, and heavily degraded former forest. It is a large bird, with a wingspan of 150–165 cm (59–65 in). The body plumage is black, and the head and neck, which are featherless, are pale orange with red or blue areas. It lacks a syrinx, so therefore its vocalizations are limited to grunts or low hisses.

The greater yellow-headed vulture, also known as the forest vulture, is a species of bird in the New World vulture family Cathartidae. It was considered to be the same species as the lesser yellow-headed vulture until they were split in 1964. It is found in South America in tropical moist lowland forests. It is a fairly large bird, with a wingspan of 166–178 cm (65–70 in), a weight of 1.65 kilograms (3.6 lb) and a body length of 64–75 cm (25–30 in). The body plumage is black, and the head and neck, which are featherless, range in color from deep yellow to pale orange. It lacks a syrinx, and its vocalizations are therefore limited to grunts or low hisses.

Gymnogyps varonai, sometimes called the Cuban condor, is an extinct species of large New World vulture in the family Cathartidae. G. varonai is related to the living California condor, G. californianus and the extinct G. kofordi, either one of which it may have evolved from. The species is solely known from fossils found in the late Pleistocene to early Holocene tar seep deposits in Cuba. G. varonai may have preyed upon carcasses from large mammals such as ground sloths.

Phasmagyps, is an extinct genus of New World vulture in the family Cathartidae, known from one Oligocene fossil found in Colorado. The genus contains a single described species, Phasmagyps patritus which is possibly the oldest New World vulture known, though its placement in the family Cathartidae has been questioned.

Emslie's vulture is an extinct species of vulture in the family Cathartidae. It is only known from a series of fossils found in western Cuba. The fossils were primarily found in caves or Quaternary asphalt deposits. It is significantly smaller than the extant C. aura. It likely became extinct during the Holocene following the extinction of Cuban Pleistocene megafauna whose bodies it would have fed on, coupled with the loss of the open savannas it would have inhabited.
