The Hoatzin (Opisthocomus hoazin), also known as the stinkbird, or Canje pheasant, is a species of tropical bird found in swamps, riparian forests, and mangroves of the Amazon and the Orinoco Delta in South America. It is notable for having chicks that possess claws on two of their wing digits.
Hoatzin have a huge range over most of tropical South America. You are most likely to see them when you visit jungle lodges in the Amazon such as Napo Wildlife Center, Tambopata Research Center, Manu Peru, Cristalino, etc. I only saw them well in Ecuador at Napo. They are really cool looking birds even if the locals do think they stink!
