Assessment Information [top]

Red List Category & Criteria: Least Concern     ver 3.1
Year Published: 2009
Assessor/s: BirdLife International
Reviewer/s: Bird, J., Butchart, S.
Justification:
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 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 may be moderately small to large, 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.
History:

Population [top]

Population: Although the species has a large global population estimated to be 25,000-100,000 individuals (Wetlands International 2006), subspecies branickii is described as 'uncommon and very local' throughout its range (Matheu and del Hoyo 1992).
