Wilpattu Wildlife: What You Will Actually See

Wilpattu is the largest national park in Sri Lanka and the quietest of the big ones. Its character comes from the villus, natural sand-rimmed lakes scattered through dry lowland forest, which draw everything to a handful of predictable edges. You will wait longer here than at Yala and you will usually wait alone, which for a lot of people is the whole point.

This is the better sloth bear park, and the reason is fruit. When the palu trees ripen in June and July the bears climb into them in daylight, which is the one time of year a sloth bear stops being a rumour. Leopard is here too and is genuinely harder than at Yala, because the forest is taller and the animal has cover.

The villus carry mugger crocodiles, wild water buffalo standing with only heads and horns showing, spot-billed pelicans and grey-headed fish eagles on the dead branches. In the forest behind them sit the grizzled giant squirrel, the Indian chameleon in the thorn scrub, and two animals that are almost pure statistics, the rusty-spotted cat and the Indian pangolin.

Highlights

Sloth Bear

Sloth Bear

A shaggy, long-clawed insect specialist that vacuums termites out of a mound loudly enough to hear from fifty metres. Where: Palu trees along the tracks and around the villus. Best: Jun-Jul, morning.

Sri Lankan Leopard

Sri Lankan Leopard

The largest leopard subspecies in the world, and on this island it is the top predator, which changes how it behaves. Where: Track edges and the margins of the villus. Best: Feb-Oct, early morning.

Grizzled Giant Squirrel

Grizzled Giant Squirrel

A cat-sized squirrel with a tail longer than its body, flowing along a branch and then freezing flat against the bark. Where: Taller woodland near water. Best: Year round.

Indian Chameleon

Indian Chameleon

Sri Lanka's only chameleon, and it is genuinely scarce here, so finding one in a thorn bush in the northwest is a proper piece of luck. Where: Thorn scrub and low trees along the tracks, and on the Mannar road beyond the park. Best: Year round.

Wild Water Buffalo

Wild Water Buffalo

Wide-swept horns spanning further than any other bovid, on an animal that is genuinely dangerous and genuinely rare in its true wild form. Where: The villus, often with only heads and horns showing. Best: Year round.

Mammals

11 species

Chital (Spotted Deer)

Chital (Spotted Deer) Common

Axis axis

The prey base the whole leopard story rests on, and the animal whose alarm call tells you where the cat is.

Tufted Grey Langur

Tufted Grey Langur Common Near Threatened

Semnopithecus priam

Long-limbed, silver-grey and black-faced, sitting in the open on a ruin or a track edge in every dry zone park.

Where: Woodland around the villus. Best: Year round.

Golden Jackal

Golden Jackal Regular

Canis aureus

The dry zone's opportunist, trotting along a track at dawn and howling in chorus at dusk so the whole park knows where it is.

Wild Water Buffalo Regular Endangered

Bubalus arnee

Wide-swept horns spanning further than any other bovid, on an animal that is genuinely dangerous and genuinely rare in its true wild form.

Where: The villus, often with only heads and horns showing. Best: Year round. Telling genuinely wild animals from feral ones is not straightforward in the field.

Asian Elephant

Asian Elephant Occasional Endangered

Elephas maximus

The largest land animal in Asia, and a genuinely wild one is worth seeking out over the camp elephants most tourists meet.

Where: Villu margins and open woodland. Best: February to October.

Sloth Bear

Sloth Bear Occasional Vulnerable

Melursus ursinus

A shaggy, long-clawed insect specialist that vacuums termites out of a mound loudly enough to hear from fifty metres.

Where: Palu trees along the tracks and around the villus. Best: Jun-Jul, morning. The best sloth bear park in the country, and the palu season is the whole reason to time a trip for it.

Sri Lankan Leopard

Sri Lankan Leopard Occasional Endangered

Panthera pardus kotiya

The largest leopard subspecies in the world, and on this island it is the top predator, which changes how it behaves.

Where: Track edges and the margins of the villus. Best: Feb-Oct, early morning. Fewer cats and far fewer jeeps than Yala. Better watching when you do connect.

Grizzled Giant Squirrel

Grizzled Giant Squirrel Rare Near Threatened

Birds

10 species

Indian Peafowl

Indian Peafowl Common

Pavo cristatus

Wild, and behaving like a wild bird: displaying on a termite mound at dawn with leopards in the same scrub.

Brown-capped Babbler

Brown-capped Babbler Occasional

Pellorneum fuscocapillus

A ground babbler that sings a clear rising three-note whistle from inside a thicket and refuses to come out.

Where: Scrub and thicket along the tracks. Best: Year round. Gives a safari day something to listen for between the mammals.

Grey-headed Fish Eagle

Grey-headed Fish Eagle Occasional Near Threatened

Icthyophaga ichthyaetus

Sits low over the water on a dead branch for hours, then drops feet first and comes up with a fish half its own weight.

Where: Dead branches overhanging the villus. Best: Year round. Pairs hold the same villus year after year, which makes it unusually findable for a big raptor.

Malabar Pied Hornbill

Malabar Pied Hornbill Occasional Near Threatened

Anthracoceros coronatus

The island's big hornbill, sealing the female into a tree hollow behind a wall of mud for the whole nesting period.

Where: Tall trees along the tracks and around the villus. Best: Year round. Heard well before it is seen. The wingbeats carry.

Python molurus

Sri Lanka's largest snake, and in the dry season it lies out at the edge of a shrinking waterhole where every animal in the park has to come.

Where: Villu margins and around rock outcrops. Best: February to October.

Indian Star Tortoise

Planning

February to October, with June and July the window that matters if the sloth bear is the reason you are going. Distances inside the park are long and the tracks are sand, so a full day is a better unit here than a short drive, and the villu circuit rewards patience at one good edge over covering ground. Take water and food in, because there is nothing inside. Sloth bears are short sighted and easily startled, and they are the one large mammal here that reacts rather than leaves.

Frequently asked questions

Is Wilpattu good for sloth bears?

It is the best park in the country for them. The bears are recorded around the palu trees along the tracks and villus, and the June to July fruiting season is when they feed in daylight and become realistically findable.

Can you see leopards in Wilpattu?

Yes, and less often than at Yala. The forest is taller and the cats have more cover, so sightings take longer. The compensation is that when it happens there is rarely another vehicle in sight.

When is the best time to visit Wilpattu?

February to October. June and July for sloth bear, which is the strongest single reason to time a trip here rather than anywhere else.

How is Wilpattu different from Yala?

Larger, wooded, much quieter and slower. Yala is thorn scrub with the leopards and the traffic; Wilpattu is dry forest around lakes, with bears, and long stretches where you see nobody.
