Distribution and population
Aplonis mavornata is known only from the type specimen, collected on Mauke, Cook Islands, by Bloxam in 1825 (Olson 1986a), and not on Cook's voyages (Pratt et al. 1987). The island was not visited by ornithologists until nearly 150 years after Bloxam's collection, by which time the species had become extinct (Olson 1986a).

Nothing is known, but like other members of the genus it is likely to have inhabited the islands forests.

Its extinction was presumably as a result of predation by introduced rats.
