Justification:
|
This species has a large range, with an estimated global breeding extent of occurrence of 50,000–100,000 km². It has a large global population estimated to be 50,000 individuals (M. Crosby in litt. 2003). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
