Micen Island.

Nature Marion Island’s plague of mice:

"When the cat’s away, the mice will play – and that old adage is unfortunately also true for Marion Island, one of two islands making up South Africa’s Prince Edward Island sub-Antarctic archipelago deep in the “Roaring Forties” of the Southern Ocean.

"The house mouse Mus musculus was accidentally introduced to Marion Island by sealers as long ago as the beginning of the 19th century, and because of its physical adaptability – it’s able to survive temperatures ranging from below freezing to hot desert conditions – this little alien mammal has thrived in the pristine island environment where it has no natural predators."

A breakfast warning. Your stomach may find some of the images distressing...
