Perdicella helena is a species of tropical tree-living, pulmonate, land snails in the family Achatinellidae. This species is endemic to Hawaii in the United States.
Perdicella helena can be found on Molokaʻi and Maui. This species has been known to enter the islands by getting stuck to feathers of birds or floating tree trunks that found their way to Hawaii. [2]
Perdicella helena can be found on the trunk, stems & leaves of certain non-pubescent plants that have the fungi they feed on. [3] They can be found on the ground and in the vegetation. [4]
Perdicella helena have a shell diameter of 3-10 mm. [4]

The poʻo-uli or Hawaiian black-faced honeycreeper is an extinct species of passerine bird that was endemic to the island of Maui in Hawaiʻi. It is considered to be a member of the Hawaiian honeycreepers, and is the only member of its genus Melamprosops. It had a black head, brown upper parts and pale gray underparts. This bird inhabited only the wetter, easternmost side of Maui, where it had rapidly decreased in numbers. With extinction threatening, efforts were made to capture birds to enable them to breed in captivity. These efforts were unsuccessful; in 2004, only two known birds remained, and since then, no further birds have been sighted. A 2018 study recommended declaring the species extinct, citing bird population decline patterns and the lack of any confirmed sightings since 2004, and in 2019, the species was declared extinct.
