Meet Moo, the tiniest leader in budgie history, who vows to purge the city of its latest blood sport. Three plucky budgerigars join her. Fudge has a voice from heaven, Barney is tarred but not feathered and Yukey hosts a magical seed. They blaze a trail to the Prime flock. Along the way they meet the shy Night Parrots, the nomadic Wheat budgies, a friendly magpie and a curious bat. But before they can begin to rescue the city’s captive birds, Moo needs to convince the powerful Humblest Guardian that their quest is noble. Will Moo and her companions have the stamina to fly back from Australia’s heartland? And will the captive budgies be rescued in time? The odds are stacked against Moo because, after all, she is only Onebird.
