The US Dropped 2,000 Poisoned Mice on Guam by Parachute — Here's What Happened to the Snakes

The US government spent $8 million throwing dead, drugged mice out of helicopters over a Pacific jungle. This is not a joke — it's the true story of the brown tree snake, the animal that wiped out 10 of Guam's 12 native forest birds, caused decades of blackouts, and forced scientists into one of the strangest wildlife control programs ever attempted. For years, experts blamed pesticides and disease for Guam's vanishing birds — because everyone "knew" a snake couldn't do this. They were wrong. This is how the truth was found, why the fix had to come from the sky, and what happened when the snakes fought back in ways nobody predicted. Sources include USGS, USDA APHIS, the US Fish & Wildlife Service, and peer-reviewed studies published in Current Biology and Nature Communications. Full citation list in the pinned comment.
