Why the stamp was issued: To commemorate the 50th anniversary of the Endangered Species Act and the endangered Guam Micronesian kingfisher.
About the stamp design: Like the others in the set, the photograph on the stamp is from Joel Sartore’s famous “Photo Ark” project. They are among over 13,000 the National Geographic photographer has taken in his quest to shoot photos of as many animal species as possible.
Special design details: Stamp includes “Endangered” and the common name of the species.
First Day City: First Day of Issue Ceremony was in Wall, South Dakota, at the National Grasslands Visitor Center. The center encourages visitors to see the 20 National Grasslands and Midewin National Tallgrass Prairie. These habitats are home to the black-footed ferret, one of the endangered species pictured in the set of stamps.
About the Endangered Species set: The Endangered Species Act of 1973 (ESA) was signed into law by President Richard Nixon on December 28. The legislation “protect[s] species and the ecosystems upon which they depend,” with a goal “to halt and reverse the trend toward species extinction, whatever the cost.” The ESA is jointly administered by the United States Fish and Wildlife Service and National Marine Fisheries Service.
In 2023, the US Postal Service celebrated the 50th anniversary of the ESA with a set of 20 Forever stamps. The stamps were issued on Endangered Species Day, which lands on the third Friday in May. Each design pictures a different endangered species, representing only a small handful of the over 1,300 plants and animals protected under the ESA as of 2023. The images used for the stamps were part of Joel Sartore’s “Photo Ark.” Partnering with National Geographic, he set out to capture 20,000 species living in zoos and wildlife sanctuaries around the world. Together, they are determined to intimately picture each species in order to educate and bring awareness to their preservation. Sartore calls his work as a photographer a “mission to document endangered species and landscapes in order to show a world worth saving.”
Thanks to the ESA, many plant and animal species that were once endangered have made a comeback. With the continued effort of conservationists, volunteers, and increased awareness, even more species can make their way back from the brink of extinction one day.
History the stamp represents: The Guam Micronesian kingfisher (Halcyon cinnamomina cinnamomina) (also known as the sihek in the native language of Guam) is an extremely rare bird native to Guam. It has been extinct in the wild since 1989 and is recognized as endangered by the US Fish and Wildlife Service as well as the government of Guam. Its greatest threats are habitat destruction and the invasive brown tree snake.
Guam Micronesian kingfishers weigh two to three ounces and measure approximately eight inches in length. Males have rusty brown (cinnamon) feathers on their head, heck, upper back, and underparts. They also have a black line around the back of their neck and eyes. The lower back, wings, and shoulders are greenish-blue while the tail itself is solid blue. Females are similar in color, but duller and with white underparts and underwings. Unlike other kingfishers, these birds feed mainly on grasshoppers, insects, and small crustaceans and lizards.
Before becoming extinct in the wild, Guam Micronesian kingfishers inhabited limestone forests, coastal lowlands, coconut plantations, and large woody gardens. Today, they are only known in captivity on the US mainland and Guam. These facilities have established breeding programs with the hope of one day reestablishing the wild population.
