‘They were beckoning to him, calling shrilly.’ Why did the seagull’s father and mother threaten him and cajole him to fly?

The young seagull was frightened. It was afraid to fly. Even though it saw its parents helping and teaching its brothers and sisters flying, it could never gather enough courage to make the first flight. This was the reason why its father and mother were calling to it shrilly and scolding it. They threatened to let it starve on its ledge if it did not fly. They did so because they wanted it to leave its fear behind and learn the art of flying.
