The Cincinnati Zoo Aviculture Department has played a crucial role in the effort to reintroduce sihek to Palmyra Atoll, a small island south of Hawaii. After nearly 40 years of raising sihek in human care, several AZA facilities joined efforts in hand-rearing and releasing nine sihek on this predator-free island. As of January 2026, all nine of the Guam kingfishers that were transferred are doing well! The introduced population has also since begun breeding. The first egg, sighted in April 2025, were the first laid in the wild in over 40 years!
Did you Know?
Despite being called a kingfisher, they rarely eat fish. Siheks are forest-dwelling kingfishers that primarily eat insects, lizards, and other small animals. The name ``Sihek`` comes from the Chamorro language. Conservation organizations increasingly use the bird's Indigenous name to honor its cultural significance to the people of Guam.
