A giant tortoise whose legendary libido has been credited with saving his species from extinction is to return to the wild on the Galápagos Islands.
Diego was among 14 male tortoises selected to take part in a breeding programme on Santa Cruz Island.
The programme has been a success, producing more than 2,000 giant tortoises since it began in the 1960s.
Diego's sex drive was said to be one of the main reasons.
The 100-year-old tortoise has fathered hundreds of progeny, around 800 by some estimates.
The programme has now finished, and Diego will be returned to his native island of Española in March, the Galápagos National Parks service (PNG) said.

He will join a 1,800-strong tortoise population, at least 40% of which park rangers believe he has fathered.
"He's contributed a large percentage to the lineage that we are returning to Española," Jorge Carrion, the park's director, told AFP news agency.
