The Asian palm civet (Paradoxurus hermaphroditus), also called common palm civet, toddy cat and musang, is a viverrid native to South and Southeast Asia. Since 2008, it is IUCN Red Listed as Least Concern as it accommodates to a broad range of habitats. It is widely distributed with large populations that in 2008 were thought unlikely to be declining. In Indonesia, it is threatened by poaching and illegal wildlife trade; buyers use it for the increasing production of kopi luwak.
Characteristics
The Asian palm civet's long, stocky body is covered with coarse, shaggy hair that is usually greyish in colour. It has a white mask across the forehead, a small white patch under each eye, a white spot on each side of the nostrils, and a narrow dark line between the eyes. The muzzle, ears, lower legs, and distal half of the tail are black, with three rows of black markings on the body. Its head-to-body length is about with a long unringed tail. It weighs . Its anal scent glands emit a nauseating secretion as a chemical defense when threatened or upset.
Distribution and habitat
The Asian palm civet is native to India, Nepal, Bangladesh, Bhutan, Myanmar, Sri Lanka, Thailand, Singapore, Peninsular Malaysia, Sabah, Sarawak, Brunei Darussalam, Laos, Cambodia, Vietnam, China, the Philippines, and the Indonesian islands of Sumatra, Java, Kalimantan, Bawean, and Siberut. It was introduced to Irian Jaya, the Lesser Sunda Islands, Maluku, and Sulawesi. Its presence in Papua New Guinea is uncertain.
It usually inhabits primary forests, but also occurs at lower densities in secondary and selectively logged forest.
It is also present in parks and suburban gardens with mature fruit trees, fig trees, and undisturbed vegetation. Its sharp claws allow climbing of trees and house gutters. In most parts of Sri Lanka, palm civets are considered a nuisance since they litter in ceilings and attics of common households, and make loud noises fighting and moving about at night.
Evolution
Palawan and Borneo specimens are genetically close, so the Asian palm civet on Palawan island might have dispersed from Borneo during the Pleistocene. It is possible that people later introduced Asian palm civet into other Philippines islands.
Behaviour and ecology
The Asian palm civet is thought to lead a solitary lifestyle, except for brief periods during mating. It is both terrestrial and arboreal, showing a nocturnal activity pattern with peaks between late evening until after midnight. It is usually active between dawn and 4:00 in the morning, but less active during nights when the moon is brightest.
Scent marking behaviour and olfactory response to various excretions such as urine, feces, and secretion of the perineal gland differs in males and females. Scent marking by dragging the perineal gland and leaving the secretion on the substrate was most commonly observed in animals of both sexes. The duration of the olfactory response varied and depended both on the sex and excretion type. The palm civet can distinguish animal species, sex, familiar and unfamiliar individuals by the odor of the perineal gland secretion.
Feeding and diet
The Asian palm civet is an omnivore feeding foremost on fruits such as berries and pulpy fruits. It thus helps to maintain tropical forest ecosystems via seed dispersal. It eats chiku, mango, rambutan, and coffee, but also small mammals and insects. It plays an important role in the natural regeneration of Pinanga kuhlii and P. zavana palms at Gunung Gede Pangrango National Park. It also feeds on palm flower sap, which when fermented becomes palm wine, a sweet liquor ("toddy"). Because of this habit, it is called the toddy cat.
Reproduction
Due to its solitary and nocturnal habits, little is known about its reproductive processes and behaviour. In March 2010, a pair of palm civets was observed when attempting to mate. The pair copulated on the tree branch for about five minutes. During that period, the male mounted the female 4–5 times. After each mounting, the pair separated for a few moments and repeated the same procedure. After completion of mating, the pair frolicked around for some time, moving from branch to branch on the tree. The animals separated after about six minutes and moved off to different branches and rested there.
Threats
Hunting
In some parts of its range Asian palm civets are hunted for bushmeat and the pet trade. In southern China it is extensively hunted and trapped. Dead individuals were found with local tribes where it is killed for its meat, in Coimbatore, Tamil Nadu, and Agra, Uttar Pradesh, between 1998 and 2003 in India.
