If you are in a visit to Sri Lanka, do not miss the opportunity to explore this amazing rain forest in Sri Lanka.

Sinharaja rain forest trek is easily tops the best rainforest treks in Sri Lanka. The forest reserve is also the last remaining primary lowland rainforest in the island nation. The term Sinharaja is a closed compound word with the meaning “Lion king”. Perhaps, it was the last hideout of the now extinct Sri Lankan lion (Panthera leo sinhaleyus). In the present “lion-less” situation, Sinharaja rainforest is unique as an eco-system that is made up of a wide range of tropical flora and fauna. To elaborate, an astounding 64% of all endemic tree species recorded in Sri Lanka occur in this small patch of rainforest. A count of 19 out of 26 birds endemic to Sri Lanka occur here. Endemism among mammals and butterflies is greater than 50%. Some of the fascinating endemic fauna at Sinharaja are Sri Lanka wood pigeon (Columba torringtoni), green-billed Coucal (Centropus chlororrhynchus), Sri Lanka white-headed starling (Sturnus senex), Sri Lanka blue magpie (Cissa ornate), ashy-headed babbler (Garrulax cinereifrons), Sri Lanka broad-billed roller (Eurystomus orientalis irisi) and Sri Lankan leopard (Panthera pardus kotiya), Sri Lankan elephant (Elephas maxiumus Maximus) and endemic purple-faced Langur (Presbytis senex).

For Sri Lanka, the Sinharaja rain forest is an important protected area that is under the supervision of the Sri Lanka Department of wildlife conservation. It is a UNESCO world heritage site and also a UNESCO man and biosphere reserve as well. There are 22 villages surrounding the forest reserve which rely on the forest for various purposes. These villagers use many ancient footpaths that lead into the forest interior. Furthermore, Birdlife international has declared it as an important bird area (IBA) through their Sri Lankan arm FOGSL. Bird watchers who visit Sinharaja may be privileged to note a rare phenomenon identified as a bird wave. It is formally known as a mixed-species foraging flock. The Sinharaja Bird Wave is the biggest and the longest studied bird wave in the world. Even mammals are known to take part in Sinharaja bird waves when hundreds of different bird species flock together to literally sweep the forest for food.
