Population justification: Despite extensive searches, the species has not had a confirmed sighting since 2011 and is now considered to be Extinct (Butchart et al. 2018).

Trend justification: The species is thought to have declined rapidly owing to the widespread and ongoing clearance of forest through logging, felling for charcoal and for conversion to sugarcane plantations and pastureland. The species is considered to have gone extinct since 2011 (Butchart et al. 2018).
