Population justification: The population was previously estimated to number 2,500-9,999 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals. However, the species's estimated range size has since increased by a factor of five, suggesting that there may be 7,500-35,000 mature individuals.
Trend justification: The species's population is suspected to be declining in line with habitat degradation, judged overall to involve the clearance of undergrowth in about 20% of its habitat (M. Mills in litt. 2005); however, the species is evidently tolerant of modified habitats, including relatively heavily cultivated areas (P. Vaz Pinto in litt. 2004, M. Mills in litt. 2005, 2012), thus the decline is thought to be slow to moderate.
