The Queen's Beasts are ten heraldic statues representing the genealogy of Queen Elizabeth II, depicted as the Royal supporters of England. 
The falcon was first used by Edward III of the House of Plantagenet as his badge. It descended to Edward IV, who took it as his personal badge, the falcon standing within an open fetterlock. Originally closed, the slightly open fetterlock is supposed to refer to the struggle Edward IV had to obtain the throne — "he forced the lock and won the throne".
