As a marine commando, Michael Chandler knew all about daunting missions, but in his new role of Ravenmaster at the Tower of London, legend would have it that the survival of the United Kingdom now rests in his hands. King Charles II, who reigned from 1660 to 1685, is thought to have been the first to insist on the protection of the ravens at the legendary 900-year-old Tower. That followed the monarch learning of an ancient prophecy stating that if the ravens ever left the fortress, it would collapse, dooming the kingdom too.

Since then, members of the Yeomen Warders -- the ceremonial guards responsible for securing the tower, in particular the Crown Jewels -- have taken care of the birds. The warders, commonly known as Beefeaters and led by a "Ravenmaster" since the late 1960s, must ensure that at least six birds live in the tower at all times, according to the rules laid down by Charles II. Michael "Barney" Chandler, 57, is only the sixth person to take on this solemn role, starting back in March.

Dressed in his black and red uniform and identifiable by his round flat-brimmed hat, Chandler commands a four-person team responsible for feeding, caring for and monitoring the ravens. Chandler, who served in Iraq and Afghanistan when in the Royal Marines, had no particular interest in birds before arriving at the Tower of London 14 years ago. "Initially, the draw was the legend of the ravens and then being here seeing them, working amongst them.

.. it was just natural," Chandler sa.
