Diego the tortoise, father to hundreds and saviour of his species, finally retires

Giant tortoise, whose reproductive efforts almost single-handedly saved his species, has been moved to an uninhabited island

Diego, the giant Galapagos tortoise whose tireless efforts are credited with almost single-handedly saving his once-threatened species, has been put out to pasture on his native island after decades of breeding in captivity, Ecuador's environment minister said.

Diego was shipped out from the Galapagos national park's breeding program on Santa Cruz to the remote and uninhabited Espanola.
