Oh my! This is stunning. I'm fond of the Puma/ Cougar/Mountain Lion, which can still be found in Arizona and the American Southwest. I also never really thought of a caribou as 'retty' but this one is very well wrought.
I was wondering the same thing....gonna check it up somewhere... *flicks into wikipedia* well don't ya know...if you now trust wikipedia both sexes has antlers but females "sheds" them in the summer while old males it is December and young ones in early spring.
