Late morning, my son and I were privileged to see two (I'm presuming they were male) Eastern Grey Kangaroos scrapping on the sodden flats between Blue Gum Rd and Birchwood Drive. There was much kickboxing going on. The fight lasted for about ten minutes. I wasn't sure who the victor was - neither animal staggered away dazed and bemused. The pair were part of a mob of about thirteen kangaroos. The females, all nonchalance, weren't paying attention to the males' hullaballoo. I've only witnessed this behavior once before, in a steep north-western stretch of Kangaroo Valley guarded by towering eucalypts.
