Takahē are an endangered, flightless bird found only in New Zealand. They were presumed extinct in the 1930s but were rediscovered by Dr Geoffrey Orbell in a remote valley in the Murchison Mountains in 1948. Despite a few examples like this, when a species becomes extinct, it is almost always gone forever.
