Ostrich
From Tardis Wiki, the free Doctor Who reference
The Ostrich is a large, flightless bird native to Earth. By 5,000,000,000, it had long been extinct. All that remained was an ostrich egg in the possession of Lady Cassandra. Myths had also spread that it had a 50-foot wingspan and could shoot fire out of its nostrils. (DW: The End of the World)
