Giraffes Fight For Territory In Epic Battle Captured On Camera (VIDEO)

In a sneak peek at its upcoming seven-part history series "Africa," Discovery revealed what's being billed as the "most violent giraffe fight ever filmed."

The clip from the "Kalahari" episode shows two male giraffes vying for territory in Namibia. The extraordinary giraffe fight, which lasts less than 90 seconds, took the film crew more than four weeks to capture, according to the BBC, which partnered with Discovery to produce the segment.

The documentary crew camped out along the Hoanib River in Namibia in order to film animals in their natural habitats. However, it wasn't until cameraman Martyn Colbeck and his associate got their "lucky break" and were able to capture a giraffe fight on film.

"Even though we were following the oestrous female and the consorting male, the fight came out of nowhere," Colbeck told the BBC, describing a female giraffe's state of sexual receptivity. "Suddenly the challenger came around the corner of a bend in the river and immediately challenged the dominant male in the most brutal way."

During the video, the two giraffes stand side-by-side and swing their 6-foot-long necks -- estimated to weigh around 500 pounds -- at each other.

"It's extremely rare to catch a giraffe fight on film," narrator Forest Whitaker says during the clip. "Most of the time they're gentle vegetarians. But to protect precious territory, they will fight."

While filmed giraffe fights are uncommon, they're not entirely out of the ordinary. In 2007, some lucky tourists stumbled upon a giraffe fight in Tanzania during a safari.

According to the World Wildlife Fund, a giraffe's kick can be powerful enough to kill a lion. Today, the "main threats to giraffes are habitat loss and poaching for meat and hides."
