What role was played by the family of the seagull to train him in the art of flying?

To train the young seagull in the art of flying, the entire family helped out. His sister and brothers encouraged him to muster up courage and try to fly. The parents called out in a shrill voice, along with cajoling and scolding him in turn. Then they threatened to let him starve. When all this proved unsuccessful, his mother tempted him by flying close to his ledge with a piece of fish in her mouth. Maddened by hunger, he dived forward to get that piece and fell into space. To save himself, he spread his wings and found that he was able to fly. Thus, the entire family helped him in making him to learn the art of flying. His parents and his brothers and sister had landed on the green surface of water ahead of him. They were calling him to do the same thing. They were flying around him. They were roaring and diving. When he was tired and weak with hunger, he could not rise. Then his family came around him crying and praising him. They offered him scraps of dog-fish because he had made his first flight successfully.
