Gehan de Silva Wijeyeratne has broken internationally significant wildlife stories, including recognising Sri Lanka as the site of the world’s largest recurring gathering of wild elephants and a key destination for leopard safaris. 

Gehan’s efforts have made him a wildlife celebrity in Sri Lanka, with over 25 published books and 400 articles. He is amongst a handful of field naturalists to write and photograph internationally-published books and field guides spanning terrestrial mammals, marine mammals, birds, butterflies, dragonflies, wild flowers and trees. Gehan was most recently the lead author and lead photographer of A Photographic Guide to the Wildlife of Sri Lanka. Published by John Beaufoy Publishing in November 2024, it is the most comprehensive photographic field guide to the island’s wildlife and covers 1,180 species.

Gehan is the Chair of the London Bird Club and a Trustee of the British Ornithologists’ Club. Back in London after ten years in Sri Lanka, he continues to promote the island as one of the world’s best all-round wildlife destinations.
