Nyctibius griseus Potoos, a relative of nightjars and nighthawks, are masters of camouflage. They sit entirely motionless on snags or branches, expertly matching the bark color and pattern to that of their plumage. They are incredibly difficult to spot, even when looking right at them. Napo River, Ecuador
Lagothrix poeppigii Woolly Monkeys are one of the larger neotropical primates, though not quite as big as some howlers. A large male Woolly is a formidable foe though. These are thick-bodied monkeys with noticeable muscle definition. They also possess a prehensile tail for hands-free movement through the trees. You can see that specialized tail in action here. Napo Province, Ecuador
Pionites melanocephala These small but very pretty parrots were moving through the rainforest canopy but stopped briefly on this perch. This is a popular species in the pet trade. Yasuni National Park, Ecuador
