Population justification: The population is estimated to number 2,500-9,999 mature individuals, from analysis of records in BirdLife International (2001), who concluded that the distribution was very patchy, the species occurred at low densities, and overall numbers must be very low, i.e. fewer than 10,000. This estimate equates to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.

Trend justification: Recent surveys have found the species to be scarce across its range, and absent from many intervening areas between known sites (Tiwari 2001). It is therefore suspected to be declining rapidly in association with the loss and degradation of its habitat.
