They are Ravens.
Beefeaters. Nobody is sure why. Some think it was because they were fed from the king's table in the middle ages, so they would be strong and healthy.
The birds that live at the Tower of London are Ravens and their continued residence at the Tower is assured because legend has it that if the ravens leave the Tower then it will fall along with the monarchy. There is a "Beefeater", or Yeoman Warder who looks after the birds and he is called the Raven Master. There are presently seven birds kept at the Tower each one is named. The legend states that at least six must remain within the Tower. The birds are called Odin, Thor, Hardey, Gwyllum, Hugine, Munin and Cedric. They are fed on a daily basis with raw meat and some dried bird food with the occassional dead rabbit thrown in complete with fur which is good for them. To stop them from escaping they have had one wing clipped which apparently doesn't hurt them but does make them fly somewhat awkwardly. There is somewhat of a history attached to the birds and a visit to the Tower of London will ensure that you learn more.
