Falconidae is a family of diurnal birds of prey and includes caracaras, laughing falcon, forest falcons, falconets, pygmy falcons, falcons and kestrels.They are small to medium-sized birds of prey, ranging in size from the black-thighed falconet, which can weigh as little as 35 grams (1.2 oz), to the gyrfalcon, which can weigh as much as 1,735 grams (61.2 oz).
The largest falcon is the gyrfalcon at up to 65 cm (26 in) in length. The smallest falcon species is the pygmy falcon, which measures just 20 cm (7.9 in). As with hawks and owls, falcons exhibit sexual dimorphism, with the females typically larger than the males, thus allowing a wider range of prey species. [10]
The falcons and caracaras are around 65 species of diurnal birds of prey that make up the family Falconidae (representing all extant species in the order Falconiformes).The family likely originated in South America during the Paleocene [1] and is divided into three subfamilies: Herpetotherinae, which includes the laughing falcon and forest falcons; Polyborinae, which includes the spot-winged ...
The peregrine falcon became an endangered species over much of its range because of the use of organochlorine pesticides, especially DDT, during the 1950s, '60s, and '70s. [18] Pesticide biomagnification caused organochlorine to build up in the falcons' fat tissues, reducing the amount of calcium in their eggshells.

The order Falconiformes (/ f æ l ˈ k ɒ n ɪ ˌ f ɔːr m iː z /) is represented by the extant family Falconidae (falcons and caracaras) and a handful of enigmatic Paleogene species. . Traditionally, the other bird of prey families Cathartidae (New World vultures and condors), Sagittariidae (secretarybird), Pandionidae (ospreys), Accipitridae (hawks) were classified in Falconifo
The genus name is the Late Latin term for a falcon, Falco, from falx a sickle, referencing the talons of the bird. [6] The species name is from the Latin rusticolus, a countryside-dweller, from rus, "country" and colere, "to dwell". [7] The bird's common name comes from French gerfaucon; in Medieval Latin, it is gyrofalco.
