“The Fwooper is an African bird with extremely vivid plumage; Fwoopers may be orange, pink, lime green or yellow. The Fwooper has been long been a provider of fancy quills and also lays brilliantly patterned eggs. Though at first enjoyable, Fwooper song will eventually drive the listener to insanity and the Fwooper is consequently sold with a Silencing Charm upon it, which will need monthly reinforcement. Fwooper owners require licences, as the creature must be handled responsibly.”
