It’s sometimes said that we are loving nature to death—with our sightseeing traffic jams to gawk at bison loitering in Yellowstone National Park, and our safari vehicles huddled together to watch lions yawn in the Masai Mara.  But few people take their affection for nature to such a destructive extreme as the bird lovers of Indonesia and Malaysia.

Roughly 35 percent of homes in that Southeast Asian region keep birds as pets. People love the sound of their singing and build them elaborately carved mahogany cages. But they prefer the birds to be wild caught, and the more unusual the better. The result, according to a new study in the journal Biological Conservation, is that wild bird populations are being drastically reduced, and some species are probably being driven into extinction.

The region is already notorious for hacking down huge swaths of old-growth forest for lumber, or to make room for palm oil and rubber plantations. But the pet trade seems to be almost as destructive to bird life, finishing off what deforestation has merely begun. Even birds that might have survived in secondary forests or on agricultural lands are vanishing.

Princeton University’s Bert Harris, lead author of the new study, focused on bird markets in Medan, Sumatra, “one of the primary hubs of the Asian wildlife trade,” with more than 200 bird species typically for sale. In a region with almost no field studies to monitor bird populations in the wild, Harris and his coauthors theorized that recording price and volume for different bird species in the marketplace could serve as a quick-and-dirty tool for detecting population trends in the wild.

It worked. By comparing current market data with a historical sample Read the rest of this entry »
