Gaur Fights
 

Gaur - scientific name Bos gaurus - are the world's largest wild cattle. They are often mistakenly called as Bison. Adult males weighing more than 2000 lbs and 6 feet at shoulder. Sharing a short clip. This was filmed with a Canon 1D Mark IV, with Canon 400mm f2.8 IS at 2.8 during dawn a couple of years back. Wish I had the C300 in those days.
