Dear Jigsaw: WTF, over?
Kangaroos Slug It Out on Suburban Street
I understand that such displays are perfectly normal in nature. Makes sense, even. However, the fact that they're doing it outside of nature (i.e., in a subdivision) makes me wonder. I'm guessing the 'roos are on a par with the deer and turkeys around here; i.e. they've gotten so used to humans that they don't scurry on sight.
Of course, that means in a pinch, you've got a handy mobile food source...
That is all.
