Peeta the Parakeet — Richard Taylor

A snake had stolen one of the eggs from Harold and Polly's nest and was thought to have been eaten while they waited eagerly for their other egg to hatch. Peeta, who had hatched a few days later, grew up with three beautiful red feathers on his left wing which his parents had never seen on another parakeet before. A few days later, he happened to meet a pigeon who told him that there was indeed another parakeet in the City who had the same red feathers as he. He then goes to rescue the parakeet just after he realizes that it must be the one who had hatched from the stolen egg!
