The Hoatzin is a mysterious bird in a category by itself all on its own.
It has been called "unique" because some of its characteristics are so unusual scientists are uncertain of it's origin and relationship to other birds.
These birds are strange and exotic.
They look like mystical birds because of their dark red eyes, bright blue faces and large spiky crest of feathers on their heads.
They are the size of a pheasant and have small heads, long necks and beautiful earthy-coloured feathers which camouflage them well.
