Hoatzin

About

The hoatzin is a species of tropical bird found in the swamps, mangroves, and riparain forests of the Amazon and Orinoco basins in South America. Often called the “stinkbird” because of its distinctive, manure-like odor, a result of its unique digestive system — the hoatzin ferments vegetation in its crop, much like cows do. This process helps it break down tough leaves, which make up most of its diet.

Another bizarre feature of the hoatzin is its chick’s claws: young birds have two claws on each wing, allowing them to climb branches — a rare and primitive trait reminiscent of prehistoric birds like Archaeopteryx. Adult hoatzins have a striking appearance, with spiky crests, blue facial skin, and reddish-brown feathers. Though awkward in flight, they’re excellent at clambering through trees, and their distinctive calls — a mix of hisses, grunts, and croaks — add to their prehistoric vibe.
