One of the smallest monkeys that we can find in Manu is the Saddleback Tamarin.. "Saguinus Fuscicollis)".
The Saddleback Tamarin is a species of tamarin from South America and occupy an extensive area of Amazonia. It can be found in Bolivia, Brazil, Colombia, Ecuador, and #Peru (in Manu & Tambopata areas.)
It is so small that weighs less than a pound (0.4 kg). and gets its name from the “saddle” of black, yellow or orange-brown colors on its back.
They have a small tail which is used to regulate its balance, this tail is not prehensile therefore is not used to move by the trees.
It food is based on small fruits, nectar and from insects that are extracted from small holes and cracks that Manu’s larger monkeys cannot reach.
Saddlebacks travel in family groups that consist of a fertile female, one or more adult males, and their puppies.
They are less active in the day than most primates, because in the morning leave the rest relatively late and retire earlier than other species (before sunset).
They spend their nights sleeping in dense thickets of canopy vines or else deep within the holes of trees.
A walk through the forests of Manu will allow you to listen to their characteristic sounds of chirping, trills and screeches and even. find them at the top of the trees.
