Population justification: This species is locally fairly common in suitable habitat (Sharpe and Lentino 2015), and considered less vulnerable than others (such as Grey-headed Warbler Basileuterus griseiceps) to removal of undergrowth for coffee plantations (Boesman in litt. 2006). Its population is estimated to number 2,500-9,999 individuals, equating to 1,667-6,666 mature individuals, which is rounded here to 1,500-7,000 mature individuals.

Trend justification: A moderately rapid and ongoing population decline is suspected on the basis of rates of habitat destruction and fragmentation (Sharpe and Lentino 2008, Sharpe and Lentino 2015), although there are no analyses to support this (J. Pérez-Emán in litt. 2012).
