The common kestrel, also known as the European kestrel, Eurasian kestrel or Old World kestrel, is a species of predatory bird belonging to the kestrel group of the falcon family Falconidae. In the United Kingdom, where no other kestrel species commonly occurs, it is generally just called "kestrel".
The Neogene is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period 23.03 million years ago (Mya) to the beginning of the present Quaternary Period 2.58 million years ago. It is the second period of the Cenozoic and the eleventh period of the Phanerozoic. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. The term "Neogene" was coined in 1853 by the Austrian palaeontologist Moritz Hörnes (1815–1868). The earlier term Tertiary Period was used to define the span of time now covered by Paleogene and Neogene and, despite no longer being recognized as a formal stratigraphic term, "Tertiary" still sometimes remains in informal use.
Falcons are birds of prey in the genus Falco, which includes about 40 species. Some small species of falcons with long, narrow wings are called hobbies, and some that hover while hunting are called kestrels. Falcons are widely distributed on all continents of the world except Antarctica, though closely related raptors did occur there in the Eocene.
The falcons and caracaras are around 65 species of diurnal birds of prey that make up the family Falconidae. The family likely originated in South America during the Paleocene and 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).
The peregrine falcon, also known simply as the peregrine, is a cosmopolitan bird of prey (raptor) in the family Falconidae. A large, crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed. It can reach over 320 km/h (200 mph) during its characteristic hunting stoop, making it the fastest animal on the planet. According to a National Geographic TV program, the highest measured speed of a peregrine falcon is 389 km/h (242 mph). However, radar tracks have never confirmed this, the maximum speed reliably measured is 184 km/h, but nobody has been able to present unimpeachable measurements of speeds even close to the ‘well-known’ 300 km/h. As is typical for bird-eating (avivore) raptors, peregrine falcons are sexually dimorphic, with females being considerably larger than males. Historically, it has also been known as "black-cheeked falcon" in Australia, and "duck hawk" in North America.
The merlin is a small species of falcon from the Northern Hemisphere, with numerous subspecies throughout North America and Eurasia. A bird of prey, the merlin breeds in the northern Holarctic; some migrate to subtropical and northern tropical regions in winter. Males typically have wingspans of 53–58 centimetres (21–23 in), with females being slightly larger. They are swift fliers and skilled hunters which specialize in preying on small birds in the size range of sparrows to doves and medium-sized shorebirds. In recent decades merlin populations in North America have been significantly increasing, with some merlins becoming so well adapted to city life that they forgo migration; in Europe, populations increased up to about 2000 but have been steady subsequently. The merlin has for centuries been well regarded as a falconry bird.
Edith Falco is an American actress. A prominent figure in American television, she is known for her roles both on stage and screen and has received numerous accolades including four Primetime Emmy Awards, two Golden Globe Awards, and five Screen Actors Guild Awards as well as a nomination for a Tony Award.
The Eurasian hobby or just hobby, is a small, slim falcon. It belongs to a group of similar falcons often considered a subgenus Hypotriorchis.
Eleonora's falcon is a medium-sized falcon. It belongs to the hobby group, a rather close-knit number of similar falcons often considered a subgenus Hypotriorchis. The sooty falcon is sometimes considered its closest relative, but while they certainly belong to the same lineage, they do not seem to be close sister species. The English name and the species name eleonorae commemorate Eleanor of Arborea, Queen or Lady-Judge and national heroine of Sardinia, who in 1392, under the jurisdiction conferred by the Carta de Logu, became the first ruler in history to grant protection to hawk and falcon nests against illegal hunters. The genus name falco is from Late Latin falx, falcis, a sickle, referring to the claws of the bird.
The lesser kestrel is a small falcon. This species breeds from the Mediterranean across Afghanistan and Central Asia, to China and Mongolia. It is a summer migrant, wintering in Africa and Pakistan and sometimes even to India and Iraq. It is rare north of its breeding range, and declining in its European range. The genus name derives from Late Latin falx, falcis, a sickle, referencing the claws of the bird, and the species name commemorates the German naturalist Johann Friedrich Naumann.
The saker falcon is a large falcon species. It breeds from Central Europe eastwards across the Palearctic to Manchuria. It is a partial migrant, which means that some part of the population is migratory, some part is not. In Europe, for example, a part of the juveniles are migrating, while adults are mostly resident. The European and West Asian migratory sakers spend the winter in the Sahel region. On migration, they cross the Middle East, the Arabian Peninsula, and Pakistan, where they are exposed to illegal trapping. The migratory birds to the east from Altai Mountains spend the winter in the Qinghai-Tibet Plateau.
The aplomado falcon is a medium-sized falcon of the Americas. The species' largest continuous range is in South America, but not in the deep interior Amazon Basin. It was long known as Falco fusco-coerulescens or Falco fuscocaerulescens, but these names are now believed to refer to the bat falcon. Its resemblance in shape to the hobbies accounts for its old name orange-chested hobby. Aplomado is an unusual Spanish word for "lead-colored", referring to the blue-grey areas of the plumage – an approximate English translation would be "plumbeous falcon". Spanish names for the species include halcón aplomado and halcón fajado ; in Brazil it is known as falcão-de-coleira.
The term kestrel is the common name given to several species of predatory birds from the falcon genus Falco. Kestrels are most easily distinguished by their typical hunting behaviour which is to hover at a height of around 10–20 metres (35–65 ft) over open country and swoop down on ground prey, usually small mammals, lizards or large insects, while other falcons are more adapted for active hunting during flight.
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.
Quaternary science is the subfield of geology which studies the Quaternary Period commonly known as the ice age. The Quaternary Period is a time period that started around 2.58 million years ago and continues today. This period is divided into two epochs – the Pleistocene Epoch and the Holocene Epoch. The aim of Quaternary science is to understand everything that happened during the Pleistocene Epoch and the Holocene Epoch to be able to acquire fundamental knowledge about Earth's environment, ecosystem, climate changes, etc. Quaternary science was first studied during the nineteenth century by Georges Cuvier, a French scientist. Most Quaternary scientists have studied the history of the Quaternary to predict future changes in climate.
The wildlife of Cyprus includes its flora and fauna and their natural habitats. Cyprus has a rich flora and a diverse fauna albeit with relatively few mammals. Like most modern countries, the natural habitats in Cyprus have been steadily disappearing, currently retaining only 20% of its original habitat due to rapid urbanization, usage of forests for commercial purposes, tourism and various other reasons. One of the features of Cyprus' habitats is the wild and sharp differences in elevations and habitats on the island as well as climate, all of which supply a diverse habitat for an array of fauna and flora. Terra Cypria was established as a trust in 1992 to conserve the Cypriot environment and its biodiversity.
The gyrfalcon, also abbreviated as gyr, is a bird of prey from the genus Falco and the largest species of the family Falconidae. A high-latitude species, the gyrfalcon breeds on the Arctic coasts and tundra, the islands of northern North America and the Eurosiberian region, where it is mainly a resident species. Some gyrfalcons disperse more widely after the breeding season or in winter, and individual vagrancy can take birds for long distances. Its plumage varies with location, with birds being coloured from all-white to dark brown. These colour variations are called morphs. Like other falcons, it shows sexual dimorphism, with the female much larger than the male.
The shaheen falcon is a non-migratory subspecies of the peregrine falcon found in southern Asia from India and Sri Lanka east to southeastern China. It has also been described as a migratory subspecies. Other common names for the subspecies include the black shaheen. The word shaheen in these names may also be spelled as shahin. This species was termed as the black shaheen by falconers to separate it from the true shaheen of Persian literature. Scholars of Persian and the Russian ornithologist Georgi Petrovich Dementiev have noted that the name shaheen in Persian literature actually referred to Falco peregrinus babylonicus.
The Cuban kestrel was a species of small falcon in the family Falconidae that was formerly endemic to the island of Cuba. It was described from fossil remains from late Quaternary deposits from several sites throughout the island.
