On October 16, 2023, the U.S. Fish and Wildlife Service finalized a rule removing 21 species from the list of species protected under the Endangered Species Act because of extinction.

The extinct species include eight of Hawaiʻi’s precious honeycreeper birds, the bridled white-eye and little Mariana fruit bat of Guam, a Texas fish, nine southeastern mussels, and the Bachman’s warbler. They join the list of 650 U.S. species that have likely been lost to extinction.
