Our Love for Exotic Pets is Emptying the Natural World

Conservation biologist David S. Wilcove was on a birding trip to Sumatra in 2012 when he began to notice that house after house in every village he visited had cages hanging outside, inhabited by the sort of wild birds he had expected to see in the forest. Nationwide, one in five households keeps birds as pets. That got him thinking, “What is this doing to the birds?”

Wilcove, who teaches at Princeton University, made a detour to the Pramuka bird market in Jakarta, Southeast Asia’s largest market for birds and other wildlife, from fruit bats to macaques. “It was this sort of Wal-Mart-size space filled with hundreds of stalls,” he recalls, “each stall of which was filled with hundreds of birds. An awful lot of them were in very poor condition, with signs of disease, feathers frayed, behaving listlessly–or thrashing around in their cages, because a lot of these are wild birds that are not at all suited to living as caged birds.” Some were species that even zoos with highly trained professional staff cannot maintain in captivity; they would die soon after purchase, “the cut flower syndrome,” he remarks. “It was really a shocking site. I’ve never seen anything like it.”

Research by Wilcove and his colleagues subsequently linked demand for birds in Indonesia’s pet marketplace to the decline Read the rest of this entry »

Sorry, Wildlife Farming Isn’t Going to End the Poaching Crisis

More than a decade ago, looking to slow the decimation of wildlife populations for the bushmeat trade, researchers in West Africa sought to establish an alternative protein supply. Brush-tailed porcupine was one of the most popular and high-priced meats, in rural and urban areas alike. Why not farm it? It turned out that the porcupines are generally solitary, and when put together, they tended to fight and didn’t have sex. In any case, moms produce only one offspring per birth, hardly a recipe for commercial success.

Wildlife farming is like that — a tantalizing idea that is always fraught with challenges and often seriously flawed. And yet it is also growing both as a marketplace reality and in its appeal to a broad array of legitimate stakeholders as a potentially sustainable alternative to the helter-skelter exploitation of wild resources everywhere.

Food security consultants are promoting wildlife farming as a way to boost rural incomes and supply protein to a hungry world. So are public health experts who view properly managed captive breeding as a way to prevent emerging diseases in wildlife from spilling over into the human population. Even Sea World has gotten into the act, promoting captive breeding through its Rising Tide nonprofit as a way to reduce the devastating harvest of fish from coral reefs for the aquarium hobbyist trade.

Conservationists have increasingly joined the debate over wildlife farming, with a view to … read the full story here.

How Bird Lovers Push Species to the Brink of Extinction

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 »
