Population justification: Extensive surveys in 2004-2006 estimated a total population of 10,181-19,765 individuals. However, the species is a cooperative breeder with a monogamous mating system, so the effective population size and the number of mature individuals may be considerably fewer. Hence we retain a lower estimate of 9,500-19,500 for mature individuals.

Trend justification: The species is suspected to have declined steadily, in line with forest loss in the wet zone of Sri Lanka. However, if the current moratorium on further logging remains in place this decline may slow.
