The last piebald I purposely ambushed at the feed zone where I'd seen it (my original spot was right when it was taking off and wind was not in my favor). Cool thing about these hunts though is that in all 3 cases I've been unable to get the animal on my first encounter with it, but have managed to find it again, either at a later time the same day, or on the next day.
Not sure how excited I should get about seeing and hunting the rare fur animals. I'm wondering because I've only come across one diamond so far (lvl 9 coyote) which I was unable to kill, but I've now found and killed 3 rare fur deer, and I've seen what I think was a rare fur bear (had blonde color to it).
