The Atoll Starling has populations on several island groups. A 2020 paper recorded the subspecies Aplonis feadensis heureka in the Ninigo and Hermit Islands; this account is limited to those observations.
Adults are black with a turquoise-green gloss over the head and body. The wings are brownish black and the eye is yellow or dark yellow. Immatures are duller and can look scaly below.
During 2019 fieldwork, birds were seen in open forest and near houses on Mal in the Ninigo Islands. A local informant reported nests in holes of large broadleaf trees.
An extinction-risk assessment has not been added yet.
