Population justification: The population within the Ampay National Sanctuary has been estimated to number almost 1,000 individuals. Although there are records outside of the sanctuary, it is not thought to be present in significant numbers in these areas (J. Valenzuela in litt. 2010). Therefore, a population band of 1,000-2,499 individuals is currently assumed, though a full population census may revise the figure upwards. This estimate equates to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals.
Trend justification: The Ampay National Sanctuary is currently thought to be the stronghold of the species, where some disturbance and cutting of Podocarpus trees occurs. However, there is no evidence of a population decline, as the population in the sanctuary was previously estimated at 600-800 individuals and is now thought to hold nearly 1,000 individuals (Collar et al. 1992, J. Valenzuela in litt. 2010).
