Brown palm civet

The brown palm civet (Paradoxurus jerdoni) is a medium‑sized member of the family Viverridae, a group of small carnivorous mammals native to Asia. Endemic to the Western Ghats of India and the island of Sri Lanka, it inhabits evergreen and semi‑evergreen forests, often at elevations from sea level up to 2,000 m. Its dense, brown‑grey pelage with a faintly mottled pattern provides camouflage among the canopy. Primarily arboreal and nocturnal, the species spends daylight hours in hollow trees or dense understory thickets, emerging at dusk to forage. The brown palm civet is listed as Least Concern on the IUCN Red List due to its relatively wide distribution and presumed large population, although local declines have been recorded. Conservation actions focus on preserving forest corridors, mitigating road mortality, and monitoring population trends across its fragmented range.

Brown palm civets are solitary for most of the year, coming together only briefly during the breeding season. They are strictly nocturnal, with peak activity occurring between 1900 and 2300 h. Individuals maintain exclusive home ranges that can span 2–5 km² in continuous forest, marked by scent glands on the throat and anal region. Territorial boundaries are reinforced through vocalizations—soft growls, hisses, and a characteristic chirrup—and by rubbing their bodies against branches. While primarily arboreal, they descend to the forest floor to cross gaps or to exploit ground‑level fruiting trees. Their communication is limited to scent marking and brief calls, reflecting a low‑density social structure that reduces direct competition for food resources.

The brown palm civet is an opportunistic omnivore. Its diet is dominated by ripe fruits such as figs (Ficus spp.), berries, and drupes, which can constitute up to 70 % of intake during the fruiting season. In addition to fruit, it supplements its nutrition with insects (beetles, moth larvae), small vertebrates (birds, rodents, amphibians), and occasional nectar from flowering lianas. Feeding usually occurs in the canopy, where the civet uses its keen sense of smell to locate fruiting trees and its dexterous forepaws to pluck prey. Daily food consumption averages 150–250 g, varying with seasonal availability. The species plays a crucial role in seed dispersal, often defecating viable seeds far from the parent tree, thereby facilitating forest regeneration.

Sexual maturity is reached at about 18–24 months for both sexes. Breeding in the brown palm civet is seasonal, typically occurring from November to February, coinciding with the peak fruiting period of many forest trees. After a gestation period of 60–70 days, females give birth to litters of one to three altricial young. The neonates are blind and weigh approximately 80–120 g. Maternal care is intensive; the mother nurses the kits for 8–10 weeks and teaches them climbing and foraging skills before they become independent at around 4–5 months of age. Males do not participate in parental care and may disperse to establish their own territories after reaching maturity.

Although classified as Least Concern by the IUCN, the brown palm civet faces growing pressures from habitat loss and fragmentation due to agricultural expansion, tea and coffee plantations, and infrastructure development in the Western Ghats. Road mortality is a significant source of adult mortality, with an estimated 5–10 % of local populations killed annually on highways intersecting forest patches. Illegal hunting for bushmeat and the pet trade, while not widespread, adds localized pressure. Population surveys suggest a modest decline of 10–15 % over the past two decades, prompting calls for enhanced protected‑area connectivity and community‑based monitoring programs to ensure long‑term viability.

• The brown palm civet is one of the few viverrids that rely heavily on fruit, making it an important seed disperser in tropical forests.
• It possesses a well‑developed scent gland on its throat, which it uses to mark territory and communicate with conspecifics.
• Unlike many carnivores, it can tolerate a high proportion of dietary sugars without apparent metabolic issues.
• Its nocturnal activity pattern aligns with the peak fruiting times of many canopy trees, reducing competition with diurnal frugivores.
• Genetic studies indicate that Paradoxurus jerdoni diverged from its closest relative, the Asian palm civet (Paradoxurus hermaphroditus), approximately 2.5 million years ago.
