Po’ouli
Discovered in Hawaii in the 1970s, the Po’ouli, or black-faced honeycreeper, was critically endangered by the late 1990s due to habitat destruction and disease. Efforts to breed the last known individuals in captivity failed, and the species was declared extinct in 2004.
Cause of Extinction: Habitat loss, disease, and predation by non-native species.
The Po’ouli’s extinction was a major loss for Hawaii’s unique biodiversity.
