The goal is not only to attract parents who feed bird or bird boys and girls who are engaged in their nests both birds and others. According to Alexander Roulin, zoologist at the University of Bern (Switzerland), puppies are also dedicated to choking when there are no parents, to decide who is hungry and will eat first. In the owl's nest, for example, a puppy will tend to shut up if one of its members tweets more. The quiet child will not thus waste his strength, but when his father, the hungry brood member, has satisfied his father, he will start kicking again to announce his turn.
