Population justification: Following a rapid increase, in 2010 the population was estimated to number a maximum of 8,000 individuals, based on the relative abundances of this species and Rodrigues Warbler Acrocephalus rodericanus (C. Jones in litt. 2010, 2013). Considering uncertainties and difficulties inherent in estimating this species's population size, the estimate is put at 4,000-8,000 individuals (C. Jones in litt. 2013, P. Steward in litt. 2013), assumed to include c.2,600-5,400 mature individuals.

Trend justification: Populations have increased in line with the recovery and expansion of native and exotic woodland (C. Jones in litt. 2000, Safford 2001). Surveys in 1999 and 2010 followed the same methods and the comparison of the estimates of 334 (1999) and 804 pairs (2010) gives an average annual growth rate of c.8% (assuming the age structure or proportion of non-breeders remained similar) (P. Steward in litt. 2013). However, it has been noted that previous surveys were conducted in the non-breeding season when the species may be only half as detectable as when breeding, and thus are likely to have underestimated numbers (C. Jones in litt. 2013). Consequently the total population size in 2010 is thought to be much larger than the 1,700 individuals estimated by Norfolk (2010). The population is still increasing as the amount of forest cover increases in area and trees increase in size (C. Jones in litt. 2013).
