Owl is a very mysterious and charismatic bird of prey that prefers night life. Owls have better hearing then all other birds and mammals in the world. Owls are able to make the most various sounds. Brushes on the head of owls are not ears. The real ears of owls are well hidden and located asymmetrically. One ear is higher, and another one is lower in order that the owl could hear well. Owls can eat prey which surpasses them in size. Flight of an owl is absolutely silent therefore a prey of an owl often suspects nothing about its attack. In spite of the fact that the owl is a night bird, it can see well also in daytime.
