How would it look if a bird has claws on its wings? Wing claws were a common feature of prehistoric birds. Hoatzins have managed to maintain their wing claws even after generations of evolution. Baby hoatzins are born with wing claws that are shed as they mature.
Flying is a difficult task for hoatzins and walking impossible. Even a 300m long flight would be a huge achievement for them. They usually prefer to live in swamps and waterside homes though they cannot swim well. However, young hoatzins can jump into water and swim when faced with danger. Their maroon eyes pop out of their blue, featherless skin around their head and their brown plumage is largely kempt.
