The Yeoman Warder Ravenmaster (also known as the Ravenmaster for short) is one of the Yeomen Warders who has the responsibility to maintain the welfare of the ravens of the Tower of London. The ravens are fed raw meat which is bought at Smithfield Meat Market by the Ravenmaster.
It is believed ravens have been living in the Tower of London since at least the time of King Charles II and legend maintains that should the ravens ever leave the Tower, the Tower and the monarchy will crumble. When he received complaints that the ravens interfered with observatory work, Charles ordered the re-siting of the Royal Observatory to Greenwich rather than remove the ravens. In order to prevent the ravens from flying away, their flight feathers are trimmed, so that they cannot fly in a straight line for any appreciable distance. The ravens are free, however, to roam the tower grounds.
The current Yeoman Warder Ravenmaster in the Tower of London is Chris Skaife who took over from Ray Stones in April 2011. The warders comment that the "real beefeaters" at the Tower of London are the ravens, which receive a daily ration of beef.
