His 1996 'Lost Animals' British Channel Four and Japanese NHK TV series of one hundred five-minute documentaries on extinct species in the 20th century was narrated by the Oscar-winning actress Greta Scacchi; and later translated into 20 languages. His 'Whale War' was the basis of a British ITV documentary. David Day has also written six illustrated books of animal stories - and three illustrated books of animal poems - for children. His 'Emperor's Panda' was runner-up for both the Governor General's Award and the National Library Award. His CBC award-winning poems have been praised by both the Canadian poet Al Purdy and the British poet laureate Ted Hughes.
