The Sri Lankan leopard (Panthera pardus kotiya) is a leopard subspecies native to Sri Lanka. It was first described in 1956 by Sri Lankan zoologist Paules Edward Pieris Deraniyagala.
Since 2020, the Sri Lankan leopard has been listed as Vulnerable on the IUCN Red List, as the population is estimated at less than 800 mature individuals, and is probably declining.The Sri Lankan leopard has a tawny or rusty yellow coat with dark spots and close-set rosettes. 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 1.04 m (3 ft 5 in) with a 77.5 cm (2 ft 6.5 in) long tail, the largest being 1.14 m (3 ft 9 in) with a 84 cm (2 ft 9 in) long tail; 11 males averaged 56 kg (124 lb), the largest being 77 kg (170 lb), and measured 1.27 m (4 ft 2 in) with a 86 cm (2 ft 10 in) long tail, the largest being 1.42 m (4 ft 8 in) with a 97 cm (3 ft 2 in) long tail.[3] The Sri Lankan leopard has possibly evolved to become a rather large leopard subspecies, because it is the apex predator in the country. Large males have been suggested to reach almost 100 kg (220 lb), but evidence for this is lacking.
Melanistic leopards are rare. Few records exist, including from Mawuldeniya, Pitadeniya, and Nallathanniya. In October 2019, the Department of Wildlife Conservation recorded live footage of a melanistic individual for the first time, a male.
The Sri Lankan leopard is still found in all habitats throughout the island in both protected and unprotected areas.
In Yala National Park, the Sri Lankan leopard as in other locations, is a solitary hunter, with the exception of females with young. Male's ranges typically overlap the smaller ranges of several females, as well as portions of the ranges of neighboring males, although exclusive core areas are apparent. They are more active and prefer hunting at night, but are also somewhat active during dawn, dusk, and daytime hours. They do not usually store their kills in trees, perhaps because similarly-sized or larger carnivores are absent in Sri Lanka. In 2001 to 2002, adult resident leopard density was estimated at 12.1 mature individuals and 21.7 individuals of all ages per 100 km2 (39 sq mi) in Block I of Yala National Park.
The Sri Lankan leopard hunts by silently stalking its prey, until it is within striking distance, when 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. Like most cats, it is pragmatic in its choice of diet, which can include small mammals, birds, and reptiles, as well as larger animals.[1] Sri Lankan axis deer make up the majority of its diet in the dry zone. The animal also preys on sambar, barking deer, wild boar, and monkeys.
No birth season or peak is apparent, with births occur across the year. Its lifespan ranges from 12 to 15 years in the wild, and up to 22 years in captivity.
The leopard is sympatric with the Sri Lankan sloth bear.
