Sury escapes from his cage to search for the Kingdom of the Birds. In his quest, he encounters mentors to encourage him, and forms unusual friendships. He also meets some seedy characters, like Madame Lafolle who lures him into a gilded cage.
Why is he willing to go through all the trouble, all the hardship, when he's not even certain the Kingdom exists? In the end he understands what his father's friend Greybird was trying to tell him all along.
Kaliki can't understand why his mother treats him so badly when he does the same things as his brothers and sisters.
An old dog tells him it's because his feathers are yellow, whereas his siblings' feathers are red. The dog and two cats help him leave the island on a boat, and he ends up on another island where the priests, because of his unusual golden feathers, make people believe he's a deity.
