How do you search for the world’s smallest monkey? Earlier this year, Nicolás Schuldt Durán took on this task after he was approached by members of an Indigenous community in Ecuador. Ever since, he’s been tapping into the knowledge of the Siekopai people and combining it with passive acoustic monitoring technology to look for pygmy marmosets. Spoiler alert: They’re still looking for this elusive species. Working in the Siekoya Remolino community in Ecuador, Durán is collaborating with Indigenous community members to track pygmy marmosets (Cebuella pygmaea), locally called leoncillo, and gather data on where they live and how they’re faring. “The community has already been setting up camera traps and running a territorial monitoring program to catch hunters and loggers,” Durán, founder of conservation technology organization Neblina Labs, told Mongabay in a video interview. “This is just adding one more tool to their toolkit to monitor biodiversity.” Pygmy marmosets are threatened by the illegal pet trade as well as deforestation in the Amazon Rainforest.

Pygmy marmosets, native to the western Amazon Basin, are so small that an adult weighs only 140-150 grams (about 5 ounces), or the weight of a small apple. They live high up in trees and are known for their high-pitched calls, including whistles that are often in the ultrasonic range and which they use to communicate with one another. Classified as vulnerable to extinction, these primates are threatened by the illegal pet trade as well as deforestation…This article was originally published on Mongabay
