Reclusive David Huntington writes rigorously meaningless poetry to great acclaim. But he lives fearfully, sleeping and working with earplugs, rarely going outside, drawing his life more closely around him every day. A wild parrot, a gift from his father, becomes the breach in the dike: Little Wittgenstein has a jungle shriek, fierce eyes, and a beak that wreaks havoc. David finally throws the bird out the window-and follows it into the world. His guilty search for the parrot takes him first to Telegraph Hill, where the parrot may have found others of its kind. Then David is lured to South America by rumors of an ancient flock in the mangrove swamps. There he meets the lovely levelheaded Fern, an American scientist who has her own reasons for searching for the birds. Will he retreat or follow the parrots' call?
