As the zoo has only three orangs now, they are easy to ID when you're there. Wousan is obviously a male with developing cheek flanges and big shoulders and arms. Chinta is clearly an adult female, quite small and slow moving. Natalia is a gangly juvenile, often playful.
@The Hedgehog You've given me an almost impossible task here. I'm afraid none of your photos is distinct enough to be sure. I think I identified another one as possibly being Wousan. Presumably you saw all three orangs and took a photo of each one? I imagine with your knowledge of orangs you were able to ID them while you were there? Can you not remember which one was which? In the end, does it really matter - the main thing is that you saw them in real life. There are plenty of photos of them in this Gallery.
