We are terrified with horror, as a siest, all surrounded by insects, ruins their nests. But fears behind the bird are in vain: it has perfectly adapted to ensure that various inhabiting insects do not give her disadvantages.
Osoed is a medium-sized birds predable in Europe and Asia. This feathered can be easily confused with another winged predator if it were not for his unusual diet. Actually, the name "Osoed" in this case speaks for itself: the bird is looking for the nests of the OS and bees and eats their larvae. Typically, during the meal, the swollen swarm flies around the siege, but nothing can do with it.
It's all about the unusual structure of the plumage of sieces. Detailed studies of feathers from various parts of the body of the bird showed their distinctive features. It turned out that they are much tougher, denser and at the same time less than those of predatory birds. But the feathers themselves are much more and they grow tightly to each other - so the sieved is as if in armor, which is not so easy to get. OS sting and bees can not penetrate through the dense and thick cover from feathers, and insects fly around in powerless malice.
But this is not all the protection of the siege. In addition, the bird feathers - especially in less protected areas of the neck and eye, are covered with a special lubricant, which is designed to scare off, bees and bumblebees.
