Two male king penguins who didn’t quite live up to their keepers’ plans for them to go forth and multiply have been moved from Berlin to Hamburg zoo.

“They’re gay, as far as we know,” said Berlin Zoo spokeswoman Christiane Reiss of penguins Stan and Olli.

“They never bred. And when it came to courtship, they only mated with one another.”

Stan and Olli were brought to Berlin under the European Conservation Programme (EEP) in a bid to bring more baby king penguins into the world and ensure the future of the species.
