Two large male Eastern Grey kangaroos are sparring and kicking each other is a display fight and then the very large dominant male from their mob comes over and shows a display of dominance. These three males are from the same mob and live together, the two sparing in the video are the alpha males offsiders and help him protect his mob from other males. This type of sparing is practice for the real thing when they have to fight of males trying to steal females or trying to take over the mob. Eastern Grey Kangaroos are endemic to the South Eastern seaboard of Australia and this video was take in central Southern New South Wales, just South of Canberra, Australia's capital city in February (late summer), close to the end of the main breeding season.
