I think, all the mountain tapirs youngs looking a little bit diffrent to each other, i've seen pics which very bright youngs. But in this case, the young was loosing his baby fur and changes to the adult colour.
How old is the current baby ? Is the female pregnant again, do you know that ?
The current baby was born in Sep 2007, so he is almost a year old. I have a pic of him in the Los Angeles Zoo gallery. As of right now, I don't know if the female is pregnant again, but I doubt she is.
