Adam’s Peak Wildlife: What You Will Actually See

Two million people climb Adam’s Peak every season and almost none of them look sideways. The mountain sits inside the Peak Wilderness Sanctuary, one of the least explored cloud forests in South Asia, and the forest either side of the pilgrim path is more interesting than the summit.

Two animals here make the point. The starry shrub frog and the Kandyan dwarf toad were both written off as extinct for more than a century, and both were rediscovered on this massif. Neither is findable on a casual visit, and both are on this page because a page that only lists what is easy is not telling you what the place is.

What you can realistically see is the highland set. Yellow-eared bulbul and dull-blue flycatcher at the forest edge, purple-faced langurs in the lower canopy, the Sri Lanka whistling thrush at the stream crossings if you are down there before light, and green and hump-nosed pit vipers in the forest at night. The streams carry the stone sucker and the banded mountain loach, and there are giant honey bee combs on the rock faces.

Highlights

Starry Shrub Frog

Starry Shrub Frog

Described in 1853, declared extinct, then found alive after a hundred and fifty six years, in the canopy where nobody had thought to look. Where: Cloud forest canopy in the sanctuary between 1,540 m and 1,679 m. Best: Year round, and effectively unfindable.

Kandyan Dwarf Toad

Kandyan Dwarf Toad

Described in 1872, unseen for a hundred and thirty three years, declared extinct, and then found again in 2009. It is the reason the extinction count fell from twenty one to eighteen. Where: Montane cloud forest streams in the sanctuary. Best: Year round.

Sri Lanka Whistling Thrush

Sri Lanka Whistling Thrush

A dark highland thrush that sings from wet rock at first light and is gone by the time the mist lifts. Where: Shaded streams and gullies in the sanctuary at dawn. Best: Year round, first light.

Golden Palm Civet

Golden Palm Civet

An endemic civet the colour of wet honey, moving through the canopy at night and almost unknown to visitors. Where: Fruiting canopy in the Peak Wilderness forest, on a spotlight walk from the lower approaches. Best: Year round.

Sri Lankan Krait

Sri Lankan Krait

An endemic krait of the wet zone hills that has bitten perhaps six people in recorded history. Where: Shaded plantation and forest edge on the lower slopes. Best: Year round, night.

Mammals

2 species

Paradoxurus zeylonensis

An endemic civet the colour of wet honey, moving through the canopy at night and almost unknown to visitors.

Where: Fruiting canopy in the Peak Wilderness forest, on a spotlight walk from the lower approaches. Best: Year round. Endemic and nocturnal. The pilgrim path at night is the wrong place to look; the forest either side of the lower approaches is the right one.

Myophonus blighi

A dark highland thrush that sings from wet rock at first light and is gone by the time the mist lifts.

Sri Lanka Wood Pigeon

Sri Lanka Wood Pigeon Rare Vulnerable

Columba torringtoniae

A big grey highland pigeon with a chequerboard collar, scarce and shrinking with the forest it needs.

Hump-nosed Lizard

Hump-nosed Lizard Occasional Vulnerable

Lyriocephalus scutatus

The only member of its genus anywhere on earth, with a bulbous knob on its nose and a bony lyre across its skull, and it is slow enough to photograph properly.

Hump-nosed Pit Viper

Hump-nosed Pit Viper Occasional

Hypnale hypnale

The commonest cause of snakebite in Sri Lanka, and small enough to sit unnoticed in leaf litter.

Where: Litter and path edges in the lower forest, at night. Best: Year round.

Sri Lankan Green Pit Viper

Sri Lankan Green Pit Viper Occasional

Trimeresurus trigonocephalus

An endemic green viper that hangs at eye level in the rainforest at night, and the one snake most visiting naturalists actually come away with.

Amphibians

6 species

Kelaart's Dwarf Toad

Kelaart's Dwarf Toad Regular Vulnerable

Adenomus kelaartii

An endemic toad in an endemic genus that is active by day, which makes it the one you can find on an afternoon walk rather than a night one.

Where: Stream margins and midstream boulders on the lower approaches. Best: Year round.

Sri Lanka Rock Frog

Sri Lanka Rock Frog Regular Vulnerable

Nannophrys ceylonensis

Its tadpoles do not swim. They crawl about on wet rock beside the torrent, grazing in a film of water a few millimetres deep, and the male guards the eggs.

Montane Hourglass Tree Frog Occasional Endangered

Taruga eques

The female kicks her own foam nest into shape with her hind legs while hanging over a highland pond, and she is nearly twice the length of the male clinging to her.

Kandyan Dwarf Toad

Kandyan Dwarf Toad Ultra rare Endangered

Insects

3 species

Common Emigrant

Common Emigrant Common

Catopsilia pomona

The butterfly behind the name Samanala Kanda, Butterfly Mountain, and the mass movement that heads for it every year.

Giant Honey Bee

Giant Honey Bee Regular

Where: Combs on cliff faces and overhangs along the pilgrim routes. Best: Year round.

Ceylon Tiger

Ceylon Tiger Occasional

Parantica taprobana

A high country butterfly found only on this island, and only above about a thousand metres.

Where: Forest edge and clearings on the lower path. Best: Year round.

No free photograph of the Ceylon tiger exists. The image shows the glassy tiger, Parantica aglea, a close relative photographed in southern India.

Planning

The pilgrimage season runs December to May and the path is lit and busy, often overnight. For wildlife that is the wrong time to be on the steps, so the lower approaches and the forest either side are the productive ground, at first light rather than on the night ascent. Outside the season the path is unlit, the weather is worse and the forest is much better. It is genuinely cold and wet at altitude. The mountain is a working pilgrimage site, and the litter problem on the popular route is severe.

Frequently asked questions

Is there wildlife on Adam’s Peak?

Yes, in the surrounding Peak Wilderness cloud forest rather than on the steps. Highland endemic birds, purple-faced langur, endemic lizards and pit vipers, montane frogs, and endemic stream fish. Two amphibians rediscovered here after a century presumed extinct are the forest’s real claim.

When is the best time for wildlife at Adam’s Peak?

Outside the December to May pilgrimage season the forest is far quieter and better, though the weather is worse and the path unlit. In season, work the lower forest at first light rather than climbing at night.

What is the starry shrub frog?

An endemic frog described in the nineteenth century and then not recorded for over a hundred years, until it was found again on this massif. It is one of a small group of Sri Lankan amphibians that came back from the extinct list.

Can you see leopards at Adam’s Peak?

They are present in the wider Peak Wilderness and are effectively never seen. Nobody should plan a visit for them.
