On the Trail of Borneo’s Clouded Leopards
Borneo is home to five species of wild cats, including the endangered Sunda clouded leopard, Neofelis diardii. I was privileged to spend time with several teams studying this elusive creature using camera traps, radio telemetry, and fecal DNA analysis. Despite several trips there, I never had a glimpse of a cloudie, but was lucky to see a marbled cat and experience life in the tropical Asian forest.
Clouded leopards are endangered in part due to poaching for their stunning coats. Researchers are studying the impact of habitat alteration and loss, including both logging and the wide-scale conversion of forest to oil palm plantations.

When not resting like zoo-born Raja, clouded leopards are climbing champions. Able to run down trees headfirst and balance with crazy long tails, this arboreal acrobat hunts monkeys, small deer and anything it can get its giant canine teeth on. Their cloud-like spots provide perfect camouflage in the Asian forest but make studying this seldom seen cat extremely difficult.

Learning how clouded leopards use their habitat will help determine ways that wild cats can co-exist with all the other uses of Borneo's forests.
