Sinharaja Forest Reserve
🇱🇰 Sri Lanka
Indian Subcontinent, Sri Lanka 712 spp. recorded
Sinharaja Forest Reserve is a dense tropical rainforest located in the southwestern wet zone of Sri Lanka. Towering dipterocarp trees, tangled vines, and damp leaf litter create a humid, multi-layered jungle canopy where muddy footpaths wind through thick vegetation. This ancient wilderness differs from dry-zone parks through its sheer density of endemic plant life and perpetual moisture, making it a crucial sanctuary for moisture-loving reptiles and amphibians.

What visitors say
He watched us intently… a magnificent SL grey hornbill then arrived dramatically E15 and the square tailed bulbul, blue magpie all had to wait for the hornbill to vacate the platform… In contrast, the brilliantly differently coloured yellow browed bulbul also dropped in…not an endemic but a lifer for us.
We also observed a Lesser Yellownape in the same area, a very beautiful, medium-sized woodpecker.
It was nice to get another look at the Malabar Trogon after already seeing it at Kithulgala … … particularly that this was the first time I also saw the female.
Within a week of returning from the Maldives (see previous post) I was in the field again-this time in the northwestern edges of Sri Lanka’s Sinharaja rainforest.
