Population justification: On the basis of distances between three neighbouring territories, the species's territory size was estimated at c.40km2. Given that it is primarily dependent on forest, this implies that the total population size for the species is probably less than 100 pairs or 200 mature individuals. It is estimated at 100-200 mature individuals, rouhgly equivalent to 150-300 individuals in total. |
|
Trend justification: No empirical data are available, but deforestation and persecution are likely to be causing an on-going decline. Given the species's longevity scaled over the past three generations it has almost certainly experienced a very rapid decline. |
