Prince William and Kate adopt baby penguin

Prince William and Kate have adopted a baby Humbolt penguin called Acorn.

According to Chester Zoo, the Humbolt penguins are an endangered species. Acorn was given to the newly married couple as a wedding present, though he will stay at the zoo with the other penguins.

"It's a real honour to be able to boast Prince William and Kate as penguin adopters," said a spokesman for the zoo. "Hopefully, the happy couple will come and see little Acorn playing in his pool very soon."

As part of the adoption pack, William and Kate can visit their baby penguin for free. The spokesman added: "They would also be able to watch Acorn being fed, and we'd be delighted if they chose to renew the adoption at the end of 12 months."

Chester Zoo chose to let the pair sponsor the Humbolt penguin after fans voted on social networking websites. The penguin won out of 400 different species, picking up 20% of the votes.

Late last month, a zoo in Rio de Janeiro named its two tigers William and Kate after the couple.
