Like the mainland clouded leopard, Diard’s clouded leopard has impressive tree climbing abilities, and is capable of running head-first down tree trunks, climbing about on the underside of branches, and hanging upside down by its hind feet with the tail providing balance. The ability to climb trees allows it to forage for food in the canopy although it mainly uses the tree branches for resting (5). Interestingly, it appears to spend less time in the trees in regions where tigers and leopards are absent (1). It was originally thought that the long canines were for preying on large ungulates (7), though recent studies show that this species feeds on a variety of terrestrial and arboreal prey including proboscis monkeys, grey leaf monkeys, young sambar deer, barking deer, mouse deer, bearded pigs, palm civets, fish and porcupines (1). Prey is either stalked on the ground or ambushed from above (6) (9).
Clouded leopards are believed to be solitary, except when breeding or accompanied by cubs (10). Most information about clouded leopard reproduction comes from captive individuals (6), but as these generally comprise the mainland species, very little is known about the reproductive biology of Diard’s clouded leopard (3).
