In the story, His First Flight, the seagull was afraid to fly until his intense hunger made him forget his fear.
The young seagull was desperate for food as he had not eaten since the previous night.
He observes his family members flying and catching fish and enjoying their food. The sight of his siblings and parents successfully feeding themselves intensifies his hunger.
As his hunger deepens, his fear of flying becomes secondary to his overpowering desire to find food. This is why when his mother offers him a piece of fish he musters the courage to jump off the cliff and dive at the food, and thus take his first flight.
