Hoatzin
The **Hoatzin** (*Opisthocomus hoazin*) is a unique and striking bird native to the Amazon and Orinoco basins in South America. Known for its distinctive, prehistoric appearance, the Hoatzin has a spiky crest and a striking blue facial patch. It is often called the "stinkbird" because of its unpleasant odor, which comes from its fermentation of food in a large, specialized crop. Hoatzins are primarily leaf-eaters, feeding on a diet of leaves and fruits. They are notable for their unusual behavior, including the ability of chicks to "walk" using their claws before they can fly.
