Red List Category & Criteria:	Least Concern ver 3.1
Year Published:	2016
Date Assessed:	2016-10-01
Assessor(s):	BirdLife International
Reviewer(s):	Butchart, S. & Symes, A.
Facilitator/Compiler(s):	Ekstrom, J., Butchart, S.
Justification: Although this species may have a restricted range, it is not believed to 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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, 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.

Population [top]

Population:

The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. (1996).

Trend Justification: The population is suspected to be in decline owing to ongoing habitat destruction through burning of its natural habitat to support cattle grazing (del Hoyo et al. 1999).

Current Population Trend:

Decreasing

Additional data:

♦ Number of mature individuals:	Unknown	♦ Continuing decline of mature individuals:	Unknown
♦ Extreme fluctuations:	No	♦ Population severely fragmented:	No
♦ Continuing decline in subpopulations:	Unknown
♦ Extreme fluctuations in subpopulations:	No	♦ All individuals in one subpopulation:	No
