Loons — the birds, which in size is slightly less than an ordinary goose. The peculiarity lies in the fact that their legs are completely not adapted for movement on the ground. Escaping to shore, the bird is forced almost to crawl a belly on the surface, but traces of this method of movement is almost gone. Therefore, the whole life of the Loon is on the water — mating games, food, sleep and rest. There are several types of loons — red-breasted, belasana, Balaklava, but the most common of these — black-throated.
