The Tower of London is beefing up its pest control measures after two of its resident ravens were killed by foxes - putting the future of the Royal Family in jeopardy according to legend.
The birds are known as "Guardians of the Tower" following superstition that there should always be six of them or the monarchy, the kingdom and the Tower itself will fall. King Charles II took the myth so seriously that he made the need for six ravens into a royal decree, which still stands today.
However, it's emerged that two of the ravens were attacked and killed by foxes earlier this year - but luckily the Tower keep eight of them just to be extra safe.
The ravens, named Jubilee and Grip, were snatched just before they were due to be locked in their cages overnight.
Tower of London staff say they are now looking into their measures to protect the ravens, and have since replaced them with two others of the same name.
