What do Muggles call a Diricawl?

Diricawl - (Mauritius, Madagascar) This plump, flightless bird escapes danger by vanishing in a burst of feathers. Muggles knew this bird as the "dodo" and believe that it is extinct, being unaware of its ability to vanish at will.
Wizards have encouraged this belief among Muggles (and the associated guilt) because it has spurred more enlightened attitudes toward the animal world.
