On the wing of the modern bird, there is not the nail. It is thought that the bird evolved from the reptiles which are near to a dinosaur in the times of the dinosaur. Therefore there was a nail on the wing of the ancient bird. A nail matches the wing of the young bird of Hoatzin and clings to a branch. On this account it is said to leave the old figure of the bird Hoatzin.
