The birds were unable to move their wings or use their dangling legs.Įleonora’s falcons have been seen building up larders of up to 20 dead birds during migration season, when prey is plentiful. Researchers came across small birds trapped in deep cavities, their flight and tail feathers removed. They hunt migrating warblers, hoopoes and other birds. Today the island is a nature reserve, where Eleonora’s falcons nest among the ruins. Mogador has the ruins of a fortress, a mosque and a prison. On the Moroccan island of Mogador, falcons seem to imprison small birds by trapping them in crevasses, presumably saving them to eat later. Most falcons eat small mammals that they hunt using eyesight, although some species hunt other birds, which they take in flight. Falcons are widely distributed on all continents of the world except Antarctica, though closely related raptors did occur there in the Eocene. It was nearly wiped out in North America by the use of pesticides, but has since made a recovery.įalcons are birds of prey in the genus Falco, which includes about 40 species. The peregrine falcon is found over most of the world and is famous for hunting birds by diving down on them at 320 km/h (200 mi/h). Peregrine falcons have been recorded diving at speeds of 320 km/h (200 mph), making them the fastest-moving creatures on Earth the fastest recorded dive attained a vertical speed of 390 km/h (240 mph). Vision and speedĪs is the case with many birds of prey, falcons have exceptional powers of vision the visual acuity of one species has been measured at 2.6 times that of a normal human. Falcons are not closely related to other birds of prey, and their nearest relatives are parrots and songbirds. The oldest fossils tentatively assigned to this genus are from the Late Miocene, less than 10 million years ago. Some small falcons with long, narrow wings are called "hobbies" and some which hover while hunting are called " kestrels".Ĭompared to other birds of prey, the fossil record of the falcons is not well distributed in time. 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. The smallest falcon species is the Pygmy falcon which measures just 20 cm. The largest falcon is the gyrfalcon at up to 65 cm in length. All these birds kill with their beaks, using a tomial "tooth" on the side of their beaks-unlike the hawks, eagles, and other birds of prey in the Accipitridae, which use their feet. The falcons are the largest genus in the Falconinae subfamily of Falconidae, which itself also includes another subfamily comprising caracaras and a few other species. Like hawks, most falcons have dark gray or brown backs and wings, with white undersides. This makes flying easier while learning the exceptional skills required to be effective hunters as adults. Fledgling falcons, in their first year of flying, have longer flight feathers, which make their configuration more like that of a general-purpose bird such as a broad wing. Long ago this was a way for people to get more food but today it is a sport.Īdult falcons have thin, tapered wings, which enable them to fly at high speed and change direction rapidly. This means people catch the birds and make them hunt for them. In some countries falcons are used in falconry. They usually have pointed wings and long tails.
