This year, the Cincinnati Zoo & Botanical Garden is celebrating its 150th anniversary by ensuring birds of a feather can indeed stick together. Yes, there’s a lot more to this globally known and respected attraction than its holiday lights. Behind the scenes, the zoo’s conservation efforts reign supreme. A medium-sized bird called the sihek — also known as the Guam kingfisher — was declared extinct in the wild after invasive brown tree snakes wiped out its population. But as part of a groundbreaking conservation effort, nine sihek chicks — including three from the Cincinnati Zoo — were relocated to a protected Pacific Ocean preserve to prepare for their historic release back into the wild. This marks the first time in nearly four decades that the species will live outside human care, thanks to a global partnership of zoos and conservationists working to restore the population. The birds will settle into their new home at The Nature Conservancy’s Palmyra Atoll, a predator-free refuge, with hopes that they will one day return to Guam — flying the coop with a fresh start. cincinnatizoo.org.
