But the rodent commandos didn't know they were on a mission: to help
eradicate the brown tree snake, an invasive species that has caused
millions of dollars in wildlife and commercial losses since it arrived a
few decades ago.
That's because they were dead. And pumped full of painkillers.
The
unlikely invasion was the fourth and biggest rodent air assault so far,
part of an $8 million U.S. program approved in February to eradicate
the snakes and save the exotic native birds that are their snack food.
