Hoatzin
Opisthocomus hoazin
Where is it found?
Forests, swamps and mangroves
Diet and foraging method
Key adaptations
Hoatzin chicks have claws on their wings to help them move around the tree canopy while they can't fly. This is crucial as many Hoatzin chicks fall out of their nests into the water below and without claws, chicks would not be able to climb out of the water back into a tree.
Social organisation and mating system
Live in family groups
Hoazins form socially monogamous pairs for breeding
Did you know that...?
Hoatzins are sometimes called "stinkbirds"!
Hoatzins have special bacteria in their stomachs to help them digest leaves, but an unfortunate consequence is that bad smells are produced during digestion, hence the nickname.
