ENDANGERED. Restricted range species: present in Vanuatu and Temotu EBA. Poorly known. Local people described the species as widespread in W mountains; in contrast, rarely encountered by visiting ornithologists, and known from very few localities. Recorded from three of the highest mountains (Mt Watiamasan, Mt Tabwemasana and Peak Santo) in, respectively, 1934, 1961 and 1991. No more than one pair has ever been seen, and several observers have failed to find the species. However, reported as 'locally common, not rare' on Peak Santo in Aug–Oct 2010 BirdLife International (2018) Species factsheet: Aplonis santovestris. Downloaded from http://www.birdlife.org on 17/01/2018. . Based on an assessment of known records, descriptions of abundance and range size, global population estimated in 2017 to number 250–1000 mature individuals, which is consistent with known population density estimates for close relatives with a similar body size, on the assumption that only a proportion of the estimated range is actually occupied BirdLife International (2018) Species factsheet: Aplonis santovestris. Downloaded from http://www.birdlife.org on 17/01/2018. . Reports of the species being eaten by locals have been questioned BirdLife International (2018) Species factsheet: Aplonis santovestris. Downloaded from http://www.birdlife.org on 17/01/2018. . Introduced cats, dogs and rats (Rattus) now widespread.
