Deepal Warakadoda is Sri Lanka's leading field ornithologist. A tour leader, photographer and conservationist, Deepal made his name with his stunning 2002 discovery of the Serendib Scops Owl in Sri Lanka's Sinharaja Forest. This owl was a species completely new to science - the holy grail for any birdwatcher. Richard Grimmett and Carol and Tim Inskipp are widely respected as the leading experts on the birds of southern Asia. Their major work was the epic Birds of the Indian Subcontinent (Helm, 1998), from which has sprung several highly acclaimed field guides.
