I find these mid-sized species every bit as charismatic as great apes.It never ceases to amaze me how incredibly little studied and terribly little understood they are.Well done to all those zoos making a serious effort on their behalf- this work in not going unnoticed.
They are a lovely group. There was a 'teenage' boy throwing his weight around, the females kept putting him back in his place, so he decided to display at us instead!
