Amazon Rainforest monkeys

As an essential part of the forest ecosystem, these species of primates are among the most influential animals in the Amazon Rainforest.

While some of these species of monkeys can be found in both Central and South America, for the purposes of this article, I’ll focus on their habits in the South American rainforest.

Without further ado, let’s get to these furry animals!

1. Black-capped capuchin monkey

The tufted capuchin is named after friars dressed in brown robes with hoods covering their heads. These animals are curious and tend to play with anything they find.

This little Amazon mammal has brownish-gray fur, and its belly is a little lighter colored. Beyond that, its thick tail is as long as its body or sometimes slightly longer.

The tufted capuchin diet relies heavily upon eggs, insects, pith, small mammals, birds, squirrels, small reptiles, nuts, and nectar. In addition to other small mammals, tufted capuchins are a confirmed predator of the titi monkey.

2. Black howler monkey

The black Howler is the largest among the Amazon Rainforest monkeys. It has a distinctive neck and a lower jaw having huge vocal cords. This primate also has a prehensile tail used for hanging and gripping on tree branches.

As the name says, this monkey is loud. In fact, it is the loudest animal in the Amazon, with its howl reaching 130 dB. (For reference, an airplane taking off is 140dB).

Males are relatively larger compared to females, who are also buff in color. Black howlers are diurnal social animals who stay in groups of 5 to 19, composed of 1 to 3 mature males and 2 to 4 mature females with their young ones.
