|Taxonomic Notes:||Nesillas longicaudata, N. brevicaudata and N. mariae (Sibley and Monroe 1990, 1993), from the Comoro Islands, are retained as species contra Dowsett and Forbes-Watson (1993) who recognise only N. brevicaudata and N. mariae.|
|Red List Category & Criteria:||Least Concern ver 3.1|

Although this species may have a restricted range, it is not believed to 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.

|Population:||The global population size has not been quantified, but the species is described as common (del Hoyo et al. 2006).
Trend Justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats (del Hoyo et al. 2006).
|Current Population Trend:||Stable|
