Deep in the Amazon rainforest of southeastern Peru, one of the world’s most elusive wild cats slips silently through the trees. Smaller than a jaguar and far less famous than a tiger, the margay is a master of the canopy, moving through tangled branches with extraordinary agility. For decades, scientists have struggled to understand this mysterious feline because it is rarely seen, mostly active at night, and equally comfortable on the ground and high above it. Now, a new study conducted by Dr. Samantha Zwicker of Hoja Nueva, a conservation nonprofit rooted in Madre de Dios, Peru, and colleagues, is shedding light on the hidden world of the margay in the Madre de Dios region of Peru. By combining ground cameras with lower-canopy cameras placed at natural margay choke points, the team captured both sides of cats moving up and down trees – a practical, lower-cost alternative to labor-intensive upper-canopy surveys.
