"This is an almost unique case of how a can be endangered by trade without specific demand. It was literally unknown in until only five years ago. There was always a local trade, within the and islands, the only places where it occurs. These islands form a chain from northern to in the Philippines. Then suddenly, hundreds of birds were captured and exported. In 1992 about 1,000 were captured, at least 700 of which were exported. In that year, at least 200 died from disease and neglect at the premises of one dealer in Jakarta. I saw dozens crowded together in the cages of a dealer in Singapore. This would have been appalling whatever the species."
