Red Howler Monkeys

A bit further along the way, we saw some red howler monkeys huddled together in the heavy rain. We also saw the Birds of Paradise (so called in Bolivia). Here they are called stinking birds. Their actual name is Quatzel. They seem to have not changed at all for mellinia, quite like the crocodile or the armadillo. They feed on leaves and parasites that no other animals feed on. This gives them an evolutionary advantage since they don't have to compere with any other animal for their food. Their stomachs have 3 chambers like the cow. This helps them digest the tough tissue of the leaves they eat. The fermentation of the leaves in their stomach gives them a bad smell which prevents predators from eating them and even humans don't like to eat it due to the bad smell. It still, is a beautiful bird.
We also saw the red headed Red Cap Cardinal. A tiny, beautiful bird with a red head.Read more
