The Guam Rail is a flightless bird that became locally extinct on Guam in the 1980s due to predation by the brown tree snake. This bird is now bred in captivity. The removal of brown tree snakes may one day lead to the reintroduction of native birds, such as the Guam rail, to the island. In 2013, the U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) Wildlife Services (WS) is partnering with the Departments of Defense and Interior, and the Guam Department of Agriculture to deploy acetaminophen-treated dead mouse baits attached to biodegradable corn starch streamers designed to snag onto branches in the dense tree canopy where the snakes feed. The successful delivery of aerial baits is a critical next step towards developing a method for large area control of the snakes and reaching the snakes in remote and inaccessible areas of Guam.
