Herpetotherinae is a subfamily of falconid birds of prey that includes eight species in two genera Herpetotheres (the laughing falcon) and Micrastur (forest falcons). [1] [2] [3] [4] Both genera are found in South America and the subfamily is basal to the other falconid subfamilies where they split off around 30.2 million years ago in the Oligocene epoch. [4] The two extant herpetotherine genera split around 20 million years ago in the Miocene epoch with the extinct genus Thegornis . [2]
The Cenozoic is Earth's current geological era, representing the last 66 million years of Earth's history. It is characterised by the dominance of mammals, birds and flowering plants. It is the latest of three geological eras, preceded by the Mesozoic and Paleozoic. The Cenozoic started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor.
Felidae is the family of mammals in the order Carnivora colloquially referred to as cats. A member of this family is also called a felid. The term "cat" refers both to felids in general and specifically to the domestic cat.
Falcons are birds of prey in the genus Falco, which includes about 40 species. Falcons are widely distributed on all continents of the world except Antarctica, though closely related raptors did occur there in the Eocene.
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.
The falcons and caracaras are around 65 species of diurnal birds of prey that make up the family Falconidae. The family is divided into three subfamilies: Herpetotherinae, which includes the laughing falcon and forest falcons; Polyborinae, which includes the spot-winged falconet and the caracaras; and Falconinae, the falcons and kestrels (Falco) and falconets (Microhierax).
A harrier is any of the several species of diurnal hawks sometimes placed in the subfamily Circinae of the 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.
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.
The New World vulture or condor family, Cathartidae, contains seven extant species in five genera. It includes five extant vultures and two extant condors found in warm and temperate areas of the Americas. The "New World" vultures were widespread in both the Old World and North America during the Neogene.
The Accipitriformes are an order of birds that includes most of the diurnal birds of prey, including hawks, eagles, vultures, and kites, but not falcons.
A hobby is a fairly small, very swift falcon with long, narrow wings. There are four birds called "hobby", and some others which, although termed "falcon", are very similar. All specialise in being superb aerialists. Although they take prey on the ground if the opportunity presents itself, most prey is caught on the wing; insects are often caught by hawking, and many different birds are caught in flight, where even the quick maneuvering swifts and swallows cannot escape a hobby.
An elanine kite is any of several small, lightly-built raptors with long, pointed wings.
Caracaras are birds of prey in the family Falconidae. They are traditionally placed in subfamily Polyborinae with the forest falcons, but are sometimes considered to constitute their own subfamily, Caracarinae, or classified as members of the true falcon subfamily, Falconinae. Caracaras are principally birds of South and Central America, just reaching the southern United States.
Phorusrhacids, colloquially known as terror birds, are an extinct family of large carnivorous flightless birds that were among the largest apex predators in South America during the Cenozoic era; their conventionally accepted temporal range covers from 53 to 0.1 million years (Ma) ago.
The plumbeous forest-falcon is a bird of prey in the family Falconidae only found in the Chocó region in Colombia and Ecuador. This rare bird has not been often spotted, which makes its study complicated. For a long time, it was considered to be part of the lined forest-falcons but it now known to be a species of its own. It is currently considered a vulnerable species because of the precarity of its habitat that is threatened by deforestation.
The white-throated caracara or Darwin's caracara is a species of bird of prey in the family Falconidae, the falcons and caracaras. It is found in Argentina and Chile.
The carunculated caracara is a species of bird of prey in the family Falconidae, the falcons and caracaras. It is found in Colombia and Ecuador.
The mountain caracara, is a species of bird of prey in the family Falconidae. It is found in puna and páramo in the Andes, ranging from northern Ecuador, through Peru and Bolivia, to northern Argentina and Chile. It is generally uncommon to fairly common. It resembles the closely related Carunculated Caracara and White-throated Caracara, but unlike those species, its chest is uniform black. Juveniles are far less distinctive than the red-faced pied adults, being overall brown with dull pinkish-grey facial skin.
The white-rumped falcon is a species of bird of prey in the family Falconidae native to Indochina. It is placed in its own monotypic genus, Neohierax.
Falconinae is a subfamily of falconid birds of prey that includes 44 species in three genera. It includes Microhierax, Polihierax, and Falco. Molecular data since 2015 has found support in the grouping of these genera, with Polihierax being paraphyletic in respect to Falco. Falconinae and their sister taxon, Polyborinae, split off from Herpetotherinae around 30.2 million years ago in the Oligocene epoch. Falconines split off from the polyborines around 20 million years ago in the Miocene epoch.
David P. Mindell is an American evolutionary biologist and author. He is currently a visiting scholar at the University of California, Berkeley, Museum of Vertebrate Zoology. Mindell's work is focused on the systematics, conservation and molecular evolution of birds, especially birds of prey. He is known for his 2006 book, The Evolving World in which he explained, for the general public, how evolution applies to everyday life.
