In an attic where Cipur's nest was in, Cipur tells Willy that he wanted to read and write like a human because he was fascinated by their knowledge and technology, but he keeps this as a secret in fear of being shunned by the other sparrows. He makes a deal with Willy that if he teaches the young sparrow how to fly, Willy will teach Cipur how to read. As the flying lesson was underway, Sissy finds Willy and Cipur and attacks. Before she could eat Willy, Cipur intervenes and lures an angry Sissy atop the roof where he trapped her head under the weight of a ceiling hatch. Under Cipur's care, Willy is taught how to fly. In return, Willy teaches Cipur how to read and write. One day, when Cipur went to find some food, Willy decides to venture out in the open to explore the outside world after learning how to fly properly. He flies back to the park and joins a flock of young sparrows, led by Red. They decided to show Willy the barn they used to hang out, until it was taken over by a big, black cat named Blackie.
