It was far away and the hope that popped into my head was that it was an elderly Japanese Serow that they used to have on exhibit. Looks more like a goral, although I cant remember them having them on exhibit in the last decade.
@TeaLovingDave Its weird because they havnt had gorals on exhibit in at least 15 years so it must have gone off exhibit young and lived unusually long.
@TeaLovingDave -- Surprisingly enough, @DelacoursLangur is actually correct (or at least mostly correct, as I do not know when it would have gone off exhibit). This individual was born at the park and will be 24 years old this year.
