Range and Population:

This species has a large range, with an estimated global Extent of Occurrence of 4,900,000 km². It has a large global population estimated to be 770,000 individuals (Rich et al. 2003). Global population trends have not been quantified; there is evidence of population fluctuations (del Hoyo et al. 1999), 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.[1]
