Population justification: The global population size has not been quantified, but the species is reported to be widespread and locally common (del Hoyo et al. 1997, Safford and Hawkins 2013).

Trend justification: The species is suspected to have undergone declines owing to habitat loss and degradation and localised hunting pressure (Safford and Hawkins 2013). Over three generations (15.39 years), tree cover loss within the range is currently estimated at rates of between 30 and 45% (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). However, the species can persist in degraded forest and within the Andohahela National Park it is slightly more abundant in recently burnt areas (Safford and Hawkins 2013, Kirwan et al. 2020), so tree cover loss alone is unlikely to be driving an equivalent population decline. Therefore, due to this uncertainty, a wide range is given for the likely rate of reduction of 10-29%.
