Kolibri has a very beautiful, unusual coloring, which also varies depending on the angle of light from the sun's rays and the angle at which you look at it. And this is not the only feature of these tiny birds. Surprising and their ability to move in space, they are able to fly and head forward and tail may hang in one place, take off almost vertically and fall almost vertically, to fabricate the air loop and plan. But what is most striking about hummingbirds is their tiny size.
