What does a hoatzin bird eat?
The Hoatzin bird is a herbivore, feeding on a variety of vegetation such as arum leaves, mangroves and other swamp vegetation. They prefer young shoots and leaves. Hoatzin are unusual as their digestive system ferments the vegetation they eat - rather like a cow's digestive system does. Hence, they can be known as the "stink bird" because they exude an unpleasant odour.

Is a hoatzin a herbivore?
If in most of birds' species, food is broken up in the gizzard, the Hoatzin makes it in its well developed muscular crop. Hoatzin feeds on certain marsh plants, such as leaves of arums (Aracea) and mangroves Avicennia, but they eat several other plants' species. They usually choose young leaves, tender shoots and buds. Hoatzin has a digestive system unique among birds, using bacterial fermentation to break down the plant materials they consume. That is the function of the crop, an enlargement of the oesophagus. This microbial fermentation converts plant cellulose included in consumed foliage into simple sugars. Hoatzin has an unpleasant odour, due to aromatic compounds included in their vegetal food. This smell is like fresh cow manure, so, this bird is only hunted for food in extremely rare occasions.
