This poorly known island warbler qualifies as Vulnerable because its very small range leaves it susceptible to chance events, such as cyclones and the introduction of alien predators.
Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.
Nesillas longicaudata, N. brevicaudata and N. mariae (Sibley and Monroe 1990, 1993), from the Comoro Islands, are retained as species contra Dowsett and Forbes-Watson (1993) who recognise only N. brevicaudata and N. mariae.
15 cm. Medium-sized, drab warbler with thin, straight bill. Greyish-olive above, off-white below with white eyebrow. Similar spp. No other passerines on the island. Voice Unreported, but presumably has the chuck call note shared by most Pacific island reed-warblers.
