If you want to pack in extra when you leave the following morning, you can visit Ingiriya’s Bodhinagala Forest Reserve – the last remaining lowland rainforest in close proximity to Colombo. Endemic bird species found here include the Brown-capped Babbler, Green-billed Coucal, Sri Lanka Hanging Parrot, Sri Lanka Jungle fowl, Sri Lanka Myna, Legge’s Flowerpacker, and the Sri Lanka Spurfowl.
Your main target, though, is Sinharaja Rainforest. Moist, muggy and mysterious, this 110 sq kms of rain forest is Sri Lanka's Heart of Darkness. Trekking through this last surviving stretch of virgin rainforest on the island, you will be enclosed in a cacophony of natural life. There are over 140 bird species here including 28 of the 33 bird species endemic to Sri Lanka. Observe the largest flocks of mixed species in the world. This mutual relationship is a method by which birds improve their feeding chances: the food preferred by one species does not necessarily interest another. Endemics like the Ceylon Birdwing, Common Tree Nymph, Red Helen can be spotted here. Other specialities are Southern Duffer, Great Crow, Blue Oakleaf, Spot Swordtail and Painted Sawtooth.
