Fun Facts About the Howler Monkey

1. There are 15 species of howler monkey and they’re all found in Central and South America. 
2. The howler monkey is the loudest primate on the Earth. Its call – a gruff, resounding roar – can be heard even 3 miles away. You can listen to it here.
3. Not just their voice, but the howler monkey’s sense of smell is unbelievably acute  – they can smell food from 2 miles away. 
4. Howler monkeys aren’t herbivores, they’re folivores – they are specialists in eating leaves.  
5. Howler monkeys are one of the few primates (including humans), who possess trichromatic colour vision. This means their eyes are sensitive to the three primary colours – green, blue & red – and they can make out the differences between colours. This helps them pick and choose the best (read – the ripest & safest) leaves to eat.
6. A particular species of howler monkey – the Mantled Howler – uses sticks as tools to drive away intruders and scare away predators. This is extremely unusual to the species as a whole; since this type of tool usage is considered the speciality of higher-order primates like chimps and humans. 
7. Howler monkeys are the second laziest animals of the planet, right after sloths. They spend 80% of their time on treetops just resting. The other 20% of the time? Well, they pee on, poop on and scream at other monkeys, animals and birds.
8. Howler monkeys are an Endangered species, because of excessive hunting and habitat loss. Save them.
