Sri Lanka holds a remarkable concentration of endemic bird species for its size, alongside major wintering grounds for migratory birds along its wetlands and lagoons. Sinharaja Rainforest, Bundala’s coastal lagoons and Kumana’s wetlands are among the island’s strongest birdwatching regions, each with a genuinely different habitat and species list. A specialist birding guide transforms the experience considerably, since many endemic species are easy to miss without local knowledge of calls and behaviour. Early morning outings consistently produce the most activity.
