The hoatzin ( Opisthocomus hoazin) lives in the Amazon and Orinoco river basins in South America .

Hatchlings are born with clawed wings — a rare, prehistoric trait — and adults give off a strong, unpleasant smell due to their digestive system.

Unlike most birds, the hoatzins have a foregut fermentation system, similar to the one found in cows.

This digestive process is highly efficient for breaking down cellulose found in leaves.
