According to ornithologists, representatives of some types combine eating of fresh food with carrion. For example, the fish eagle, as well as a number of closely related birds mainly feeding on live production can quite be fed also on corpses of mammals.
Who such deathbirds and what they are
Among birds predators there are representatives of specialized forms which eat practically only drop now. It is possible to distinguish an ordinary Egyptian vulture, a white-headed vulture, the Indian big-eared signature stamp and also the bearded man or a yagnyatnik from the most striking examples of deathbirds - all of them meet in the territory of Eurasia and Africa. In America carry a condor to similar birds, a royal signature stamp and a signature stamp to an urub, known also as the American black katarta.
Many birds in the past were predators, having replaced this type of food with the use of drop over time.
Birds of all these a look possess quite big bearing surface, they are very well adapted for long flights - quite so they look for corpses of large animals. Claws in the course of evolution became at them stupid and weak, having made their paws almost unsuitable for hunting for live production.
Having found the purpose, deathbirds begin to eat away internals, continuing then to peck out drop from within. According to scientists, these it is possible to explain them very long, and sometimes as, for example, at the American signature stamps, a naked neck. It is supposed that in the course of evolution the plumage does not prevent deathbirds to peck out carcass of the died animal, and on their neck there are no decaying food remains. Among deathbirds there are those who prefer already quite decayed corpses of animals (for example, a white-headed vulture), and such as bearded man which choose exclusively fresh meat. Also process of absorption of food differs - if the vulture, eating away drop from within, as a result does not touch skin, tendons and a skeleton, then brodach eat generally bones. It is interesting that the stomach of these birds perfectly copes with such at first sight heavy food. Even bearded men bring up the baby birds bones which can reach in length up to 20 cm.
Way of life of birds deathbirds
Representatives of many species of deathbirds can gather at production in packs. Usually they unite in the course of search of hulks, together soaring in air. In a different way signature stamps to an urub behave - these birds sit on the top branches of trees more often, trying to catch a smell therefore at them, in comparison with other deathbirds, the sense of smell and the olfactory device is very well developed.
The eagle buffoon living in the territory of Africa prefers to be fed mainly with snakes and lizards, however willingly eats also drop. Cases when they attacked on signature stamps are known, forcing them to otrygivat eaten.
Deathbirds differently approach the production: to an urub, for example, it is capable to fall literally to hulk, having noticed it from height. Only over the earth it slightly opens the huge wings, and bearded men, on the contrary, are capable to turn long enough in air, gradually decreasing. Having fallen at some distance from the production, they sit down on the earth, and then without hurrying begin to walk to it.
