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?”

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 »
