Ornithologists said they were surprised the great spotted woodpecker could fly, let alone feed, because of the size of its bill.

Tony Richardson, of the RSPB, said the woodpecker had a "serious beak deformity".
"It's probably 120% bigger than it should be," he said. "A beak grows much like hair and nails on a human, but natural wear and tear should keep it in check. Many birds wouldn't be able to survive with this handicap - but luckily woodpeckers have enormous tongues, so this one is still able to gather food."
