Assessment Information [top]

Red List Category & Criteria:	Least Concern ver 3.1
Year Published:	2012
Date Assessed:	2012-05-01
Assessor(s):	BirdLife International
Reviewer(s):	Butchart, S. & Symes, A.
Facilitator/Compiler(s):	Butchart, S., Temple, H.
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 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.
