Guam

Six Guam kingfishers, known locally as sihek, have been released into the wild, marking their return from nearly four decades of being extinct in the wild. Sihek became extinct in the wild from their native Guam in 1986 due to the introduction of the brown tree snake, but a captive-breeding program has kept the species alive since then. This release, on the predator-free Palmyra Atoll, about 3,700 miles east of Guam, is part of a larger plan to establish a breeding population there, with the ultimate goal of returning the sihek to Guam once the threat from brown tree snakes is addressed.
