| The Distribution of the Sri Lankan Leopard | |
The Sri Lankan leopard (Panthera pardus kotiya), colloquially known as Kotiya (කොටියා) in Sinhala and Puli in Tamil, is a subspecies of leopard native to Sri Lanka. Classified as Endangered by IUCN, the population is believed to be declining due to numerous threats including poaching for trade and human-leopard conflicts.[1]

The Sri Lankan leopard has a tawny or rusty yellow coat with dark spots and close-set rosettes, which are smaller than in Indian leopards. Seven females measured in the early 20th century averaged a weight of 64 lb (29 kg) and had a mean head-to-body-length of 3 ft 5 in (1.04 m) with a 2 ft 6.5 in (77.5 cm) long tail, the largest being 3 ft 9 in (1.14 m) with a 2 ft 9 in (84 cm) long tail; 11 males averaged 124 lb (56 kg), the largest being 170 lb (77 kg), and measured 4 ft 2 in (1.27 m) with a 2 ft 10 in (86 cm) long tail, the largest being 4 ft 8 in (1.42 m) with a 3 ft 2 in (97 cm) long tail.[2]
The Sri Lankan leopard is the country's top predator. Little has been known about it in the past, but ongoing studies in the framework of The Leopard Project, run by The Wilderness and Wildlife Conservation Trust, indicate that they are still distributed throughout the island both inside and outside of protected areas. The leopard has been observed in a variety of habitats including dry evergreen monsoon forest, arid scrub jungle, low and upper highland forest, rainforest, and wet zone intermediate forests.
A recent study has shown that Yala National Park has one of the highest recorded densities of leopards in the world, although this animal is still considered to be endangered. The Wilpattu National Park is also known as a good place to watch leopards. Leopards tend to be more readily observed in parts of Sri Lanka than in other countries where they share their habitat with more dominant competitors, such as lions or hyaenas.
A study in Yala National Park indicates that Sri Lankan leopards are not any more social than other leopard subspecies. They are solitary hunters, with the exception of females with young. Both sexes live in overlapping territories with the ranges of males overlapping the smaller ranges of several females, as well as overlapping the ranges of neighbouring males. They prefer hunting at night, but are also active during dawn and dusk, and daytime hours. They rarely haul their kills into trees, which is likely due to the lack of competition and the relative abundance of prey. Since leopards are the apex predators they don't need to protect their prey.[3]
Like most cats, the Sri Lanka leopard is pragmatic in its choice of diet which can include small mammals, birds, reptiles as well as larger animals. Axis or spotted deer make up the majority of its diet in the dry zone. The animal also preys on sambar, barking deer, wild boar and monkeys.[3]
The cat has been known to tackle almost fully grown buffalos.
The Sri Lankan leopard hunts like other leopards, silently stalking its prey until it is within striking distance where it unleashes a burst of speed to quickly pursue and pounce on its victim. The prey is usually dispatched with a single bite to the throat.
There appears to be no birth season or peak, with births scattered across months.[3] A litter usually consists of 2 cubs.
The survival of the Sri Lankan leopard is threatened due to poaching, habitat loss, and persecution. Despite these threats, the animal is highly adaptable and is able to live in close proximity to human settlements.
Further research into the Sri Lankan leopard is needed for any conservation measure to be effective. The Leopard Project under the Wilderness and Wildlife Conservation Trust (WWCT) is working closely with the government of Sri Lanka to ensure this occurs. The Sri Lanka Wildlife Conservation Society will also undertake some studies. The WWCT is engaged in the central hills region where fragmentation of the leopard's habitat is rapidly occurring.
As of December 2011, there are 75 captive Sri Lankan leopards in zoos worldwide. Within the European Endangered Species Programme 27 male, 29 female and 8 unsexed individuals are kept.[4]
Panthera pardus kotiya is the kotiyā proper.[5] But due to a nomenclature mishap that occurred in the late 1980s, "kotiyā" has now become the colloquial Sinhala term for tiger, and "diviyā" (දිවියා) is used for the leopard. In late 80s and early 90s, the word 'kotiya' was being frequently incorrectly translated into English as "tiger" in Sri Lankan media due to incorrect information that was received from the then head of the Wildlife Department in Sri Lanka. He had allegedly said that "there are no kotiyas (tigers) in Sri Lanka but diviyās", misinterpreting Panthera pardus kotiya as "diviyā", the Sinhala term used for small wild cats. Although it is correct that there are no tigers in Sri Lanka, the formal Sinhala word for tiger is "viyagraya" and not "kotiyā".
Sri Lankans started to use "kotiyā" to mean "tiger", so "diviyā" was chosen for "leopard".
The term "diviyā" has been used for centuries in Sri Lanka to refer to smaller wild species of the cat family such as "Handun Diviyā" or "Kola Diviyā" (both names are used interchangeably for the Fishing Cat and the Rusty-spotted cat).
A further complicating factor is that the Liberation Tigers of Tamil Eelam (Tamil Tigers) were colloquially known to the Sinhala-speaking community as 'Koti', the plural form of 'Kotiyā'.
