The word “eagle” is generally used to describe the large diurnal gliding raptors. Eagles belong to the family Accipitridae.
The eagle family (or Accipitridae) encompasses most species of diurnal raptors: bazas, falcons, buzzards etc. Eagles are birds that vary considerably in size ranging from 20 to 150 cm. They have a hooked beak that is trimmed at the base with thick wax. They also have powerful legs and a sharp vision.
The eagle is represented in France by several species such as the Golden eagle, Bonelli’s eagle, the Booted eagle and the Short-toed eagle, etc. With low reproductive potential, these species are unfortunately excessively hunted and poisoned by pesticides or these endangered species are legally protected.
Eagles are diurnal gliding birds of prey that are considerably different from hawks and falcons (Falconidae). They can be differentiated from other raptors of the same family by the fact that their legs are feather-covered up to their toes.
Like all raptors, eagles have powerful legs with large claws to seize their prey. They also have an acute sense of vision, which enables them to identify and observe their prey from a distance of more than 2 km.
Eagles reach speeds of 50-70 km / h when gliding and of about 28 km / h when flying while carrying a fish. These animals can dive at speeds of about 120-160 km / h, but rarely dive vertically.
Geographically we can find eagles in all regions of the world except Antarctica. These animals inhabit all habitat types, ranging from forests to urban areas. Eagles are partial migrants. If the areas where eagles are found are located close to open water, the animals tend to remain on site all year round. However, if the water bodies freeze in winter, the eagles are unable to find food and are consequently forced to migrate south or to the coast. The eagle chooses its migration routes according to the thermal currents and the availability of food resources. To go upwards they use the rising updrafts created by the wind hitting against the cliffs and other land feature. Migrations usually take place during the day, when thermal currents are produced by the sun.
