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 under 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 size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern. The status of this species was recently reassessed against the IUCN Red List criteria at national level for the Action Plan for Australian Birds 2020 (Garnet and Baker 2021), and not found to approach or meet the thresholds for threatened status, thereby supporting its continuing treatment as globally Least Concern.
Population justification
The global population size has not been quantified, but the species is described as common (Morcombe 2000). The trend direction for this species is difficult to determine owing to the positive and negative processes affecting it (Higgins et al. 2006).
