The Brown Falcon, Falco berigora, is a member of the Falcon Genus found in the drier regions of Australia Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates Birds ( class Aves) are bipedal endothermic ( Warm-blooded) Vertebrate animals that lay eggs. The order Falconiformes is a group of about 290 Species of Birds that include the diurnal birds of prey. Nicholas Aylward Vigors (1785 &ndash October 26, 1840) was an Irish Zoologist and Politician.

The falcons and caracaras are around 60 species of diurnal birds of prey that comprise the family Falconidae. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank. In Biological classification, family ( Latin The family is divided into two subfamiles, Polyborinae, which includes the caracaras and forest falcons, and Falconinae, the falcons, kestrels and falconets. Caracaras are birds of prey in the family Falconidae They are principally birds of South and Central America, just reaching the southern USA Forest falcons are members of the Genus Micrastur, part of the family Falconidae. A falcon (fɔlkən or fælkən is any Species of raptor in the Genus Falco. The name kestrel is given to several different members of the Falcon genus Falco. They differ from other Falconiformes in killing with their beaks instead of their feet. They have a "tooth" on the side of their beak for the purpose. The family has a cosmopolitan distribution across the world, absent only from the densest forest of central Africa, some remote oceanic islands, the high Arctic and Antarctica. In Biogeography, a Biological category of living things is said to have cosmopolitan distribution if this category can be found almost anywhere around the world The Arctic is the Region around the Earth 's North Pole, opposite the Antarctic region around the South Pole. Some species have exceptionally wide ranges, particularly the cosmopolitan Peregrine Falcon, which ranges from Greenland to Fiji and has the widest natural breeding distribution of any bird. The Peregrine Falcon ( Falco peregrinus) also known simply as the Peregrine, and historically as the "Duck Hawk" in North America is a Greenland (Kalaallit Nunaat meaning "Land of the Greenlanders" Grønland is a self-governing Danish Province located between the Fiji (Matanitu ko Viti फ़िजी officially the Republic of the Fiji Islands (Matanitu Tu-Vaka-i-koya ko Viti फ़िजी द्वीप समूह गणराज्य Other species have more restricted distributions, particularly island endemics like the Mauritius Kestrel. Endemism is the Ecological state of being unique to a place Endemic species are not naturally found elsewhere The Mauritius Kestrel ( Falco punctatus) is a Bird of prey from the family Falconidae endemic to Mauritius. Most habitat types are occupied, from tundra to rainforest and deserts, although they are generally more birds of open country and even forest species tend to prefer broken forest and forest edges. In physical Geography, tundra is an area where the Tree growth is hindered by low temperatures and short growing seasons Rainforests are Forests characterized by high Rainfall with definitions setting minimum normal annual rainfall between 1750–2000 mm (68-78 inches A desert is a Landscape or region that receives very little precipitation. Some species, mostly in the genus Falco, are fully migratory, with some species in Eurasia and wintering entirely in Africa, other species may be partly migratory. The Amur Falcon has one of the longest migrations, moving from East Asia to southern Africa. The Amur Falcon ( Falco amurensis) formerly Eastern Red-footed Falcon, is a small raptor of the Falcon family

Falcons and caracaras are small to medium sized birds of prey, ranging in size from the Black-thighed Falconet, which can weight as little as 35 g, to the Gyrfalcon, which can weigh as much as 1735 g. The Black-thighed Falconet ( Microhierax fringillarius) is one of the smallest birds of prey. The Gyrfalcon ˈdʒɜrˌfɔlkən or ˈdʒɜrˌfælkən ( Falco rusticolus) also spelled Gyr Falcon, sometimes Gerfalcon, is the largest They have strongly hooked bills, sharply curved talons and excellent eyesight. The plumage is usually composed of browns, whites, chestnut, black and grey, often with barring of patterning. Plumage refers both to the layer of Feathers that cover a Bird and the pattern colour and arrangement of those feathers There is little difference n the plumage of males and females, although a few species have some sexual dimorphism in boldness of plumage. Sexual dimorphism is the systematic difference in form between individuals of different Sex in the same Species.

Falcons and caracaras are carnivores, feeding on birds, small mammals, reptiles, insects and carrion. In popular imagination the falconids are fast flying predators, and while this is true of the genus Falco and some falconets other species, particularly the caracaras are more sedentary in their feeding. The forest-falcons of the Neotropics are generalist forest hunters. In Biogeography, Neotropic or Neotropical refers to one of the world's eight terrestrial Ecozones This ecozone includes South and Central America the Several species, particularly the true falcons, will stash food supplies in caches. [1] They are solitary hunters and pairs guard territories, although they may form large flocks during migration. Bird migration refers to the regular seasonal journeys undertaken by many species of Birds Bird movements include those made in response to changes in food availability Some species are specialists, the Laughing Falcon specialises in snakes, others are more generalist. The Laughing Falcon, Herpetotheres cachinnans, also called the Snake Hawk, is a medium-sized Bird of prey in the falcon family, the only member A snake is an elongate Reptile of the suborder Serpentes Like all reptiles snakes are covered in scales.

The falcons and caracaras are generally solitary breeders, although around 10% of species are colonial, for example the Red-footed Falcon. A bird colony is used to refer to large aggregations of individuals of one or more Species of Bird that roost or nest in close proximity at a particular location The Red-footed Falcon ( Falco vespertinus) formerly Western Red-footed Falcon, is a Bird of prey. [2] They are monogamous, although some caracaras may also employ alloparenting stratergies, where younger birds help adults (usually their parents) in raising the next brood of chicks. Monogamy is the custom or condition of having only one mate in a Relationship, thus forming a Couple. In Biology and Sociology, alloparenting is where individuals other than the actual parents act in a parental role Nests are generally not built (except by the caracaras), but are co opted from other birds, for example African Pygmy-falcons nest in the nests of weavers, or on the ledges on cliffs. The African Pygmy-falcon ( Polihierax semitorquatus) is a Falcon that lives in eastern and southern Africa, the smallest Raptor of the continent Around 2-4 eggs are laid, and mostly incubated by the female. Incubation is the process by which Birds hatch their eggs, and to the development of the Embryo within the egg Incubation times vary from species to species and are correlated with body size, lasting 28 days in smaller species and up to 35 days in larger species. Chicks fledge after 28-49 days, again varying with size. Fledge is the stage in a young Bird 's life when the feathers and wing muscles are sufficiently developed for flight

Falcons and caracaras have a complicated relationship with humans. In ancient Egypt they were deified in the form of Horus, the Sky and Sun God, and was the ancestor of the Pharaohs. This article is about the country of Egypt For a topic outline on this subject see List of basic Egypt topics. Caracaras also formed part of the legends of the Aztecs, and are today the national emblems of Mexico. Aztec is a term used to refer to certain ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language and who achieved political The United Mexican States ( or commonly Mexico (ˈmɛksɪkoʊ () is a federal constitutional Republic in North America. Falcons were important in the (formerly often royal) sport of Falconry. Falconry or hawking is an Art or Sport which involves the use of trained raptors (birds of prey to hunt or pursue game for humans They have also been persecuted for their predation on game and farm animals, and that persecution has led to the extinction of at least one species, the Guadalupe Caracara. The Guadalupe Caracara, Caracara lutosa or lotusos, is an extinct Bird of prey belonging to the Falcon family (Falconidae Several insular species have declined dramatically, none more so than the Mauritius Kestrel, which at one time numbered no more than four birds. The Mauritius Kestrel ( Falco punctatus) is a Bird of prey from the family Falconidae endemic to Mauritius. Around four species of falcon are considered vulnerable to extinction by the IUCN, with one species, the Saker Falcon, listed as endangered. The Saker Falcon ( Falco cherrug) is a very large Falcon. This species breeds from eastern Europe eastwards across Asia to An endangered species is a population of an organism which is at risk of becoming Extinct because it is either few in numbers or threatened by changing environmental or predation
