Justification of Red List Category
This species has an extremely 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 increasing, 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 is extremely large, and hence does not 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 is estimated to number 1,100,000 mature individuals (Partners in Flight 2020) and is increasing (Meehan et al. 2018; Partners in Flight 2020; Wetlands International 2020).
The species is undergoing a large increase (Meehan et al. 2018; Partners in Flight 2020; Wetlands International 2020). Over the past three generations (17.4 years) the rate of increase equated to c.140%, although it is noted that there is a high amount of data deficiency for the species (Pardieck et al. 2018).
