Justification of Red List Category
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
The global population size has not been quantified, but the species is reported to be common throughout its range (del Hoyo et al. 1997, Erritzøe et al. 2011), including within Ankarafantisika National Park and other protected areas (Kirwan et al. 2020). Around Ampijoroa it is commoner in disturbed forest, with densities of up to 25.7 individuals/km2 in burned forest compared to 16.7 individuals/km2 in intact forest (Chouteau et al. 2004).
Although tree cover loss within the range is currently estimated at around 25% across three generations (15 years; Global Forest Watch 2021, using Hansen et al.  data and methods disclosed therein), the species persists in degraded habitats and may even benefit from burning (Chouteau et al. 2004, Erritzøe et al. 2011). The population is therefore suspected to be stable in the absence of evidence for any declines or substantial threats. However, repeated monitoring over a longer timeframe is required to determine any lasting population impacts.
