Golden-handed Tamarins are small agile monkeys living in groups. When noticed they move quite fast before you even noticed them. So when you want to take a picture of them, you must always be prepared for the worse. When I noticed a group of Golden-handed Tamarins I was already too late. This one just gave me a quick glance before departing. So it looks like it was peeking through and I didn't manage to get a full body shot.
