Pied Tamarin (Saguinus bicolor)
I consider this to be the most valuable photo in my collection. Not for its technical quality, which is quite poor. It is the rarity, the bizarre specie, and the extreme case of luck I had capturing it.
The night before, our guide spoke of a mystical "bat monkey", half monkey, half bat. As he was drinking, I thought he was kidding, but I decided to push my luck anyway and got up real early the next morning to visit an area of fruit trees, where there'd be a tiny chance to spot them.
There was no need for that though. A troup of five was right above me as I got out of our lodge. They were travelling across the high tree tops very fast and I got frustrated for only shooting blurry photos and the leafs and trees blocking a good view.
Until I got lucky, almost out of sight, for a split second one of them turned around to look back at me. Here it is, the bat monkey, or Pied Tamarin. Extremely rare and almost extinct. Furry, a bat's face and claws and a long tail. Zoom in to see its bizarre face.
The pied tamarin is an endangered primate species found in a restricted area in the Brazilian Amazon Rainforest.
