‘Extinct’ Guam kingfisher takes flight again after nearly 40 years
Six Guam kingfishers — known as sihek — took their first wild flight in nearly 40 years when they were released on Palmyra Atoll, a predator-free Pacific refuge, in September 2024. The species was declared extinct in the wild in 1988, and every sihek alive today descends from just 29 birds rescued in the 1980s. Their return is the result of a global rescue effort spanning continents, with zookeepers from Kansas to London hand-rearing chicks and accompanying them to the Pacific. Each released bird now wears a tiny tracker as it learns to hunt on its own. It’s a quiet reminder that even species written off as lost can find their way back, when people refuse to give up on them.
