|Taxonomic Notes:||Aerodramus brevirostris (del Hoyo and Collar 2014) was previously placed in the genus Collocalia and split as C. brevirostris and C. rogersi following Sibley and Monroe (1990, 1993).|
|Red List Category & Criteria:||Least Concern ver 3.1|

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.

|Population:||The global population size has not been quantified, but the species is reported to be common throughout most of breeding range (del Hoyo et al. 1999).|
Trend Justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
|Current Population Trend:||Stable|
