Photographer William Suen Kai-yuen took up wildlife photography seriously four years ago when he visited Africa and witnessed vast herds of animals migrating.
Since then he has travelled thousands of kilometres lugging 70 kilograms of camera equipment to document on celluloid, Asia-Pacific's coral reefs, the animals of Australia and the birds of Mai Po.
In an average week, Suen, a magazine publisher who emigrated to Hong Kong from Taiwan in the 1970s, spends about two days photographing birds at the Mai Po reserve.
In a bid to learn more about one of the reserve's prized visitors, the rare black-faced spoonbill, he has also visited the bird's Taiwanese habitat many times.
Exhibitions of his wildlife photography have made Suen a popular figure in Taiwan and this year he will make his debut on the mainland.
During the summer Suen will track pandas in their remote mountain habitat before organising an exhibition in Beijing.
