Birds of prey are considered those that feed on prey. These birds can be classified into two orders: Falconiformes (vultures, eagles, hawks) and estrigiformes (owls, owls, tawny). The first are diurnal, live mainly in the high peaks, are skillful flying and feed exclusively on meat. Many species are great hunters of birds in flight, like a falcon, while others, like the vulture, can fly for several hours without flapping their wings waiting for their prey die, so jump on it. The condor is the largest bird among the hawks. It has about 3 meters wide, lives in the Andean mountains and high mountain ranges of America and feeds mainly on dead animals. The estrigiformes, however, are nocturnal predators that feed on rodents and insects. The eyes are on the front of his face, as in man, and have adaptations to life at night: the cells that register light pigment rhodopsin contain in abundance, which makes them more sensitive to the light source, the pupil is extremely long and the number of cells five times the vision of man.
While the condor measures 1.60 m in length, the common owl, measuring only 20 cm.
There are several species of hawks. Prominent among them are the velvetleaf (whose favorite food is the lark, but also eats mammals and insects), kestrel (which feeds only on small terrestrial animals, frogs, lizards and insects) and the peregrine falcon (which is migratory and feeds on pigeons, herons, bustards and other birds).
