Giraffes filmed in brutal battle
Cannot play media. Sorry, this media is not available in your territory.
A brutal battle between male giraffes has been caught on camera by filmmakers for the landmark natural history series Africa, coproduced by the BBC and Discovery.
Although males are known to fight, their exchanges are rarely this aggressive.
"It took four weeks of waiting to capture about 60 seconds of fight," said cameraman Martyn Colbeck who described the sequence he filmed as "staggering".
Africa begins on BBC One, Wednesday 2 January 2013 at 2100 GMT.
