Justification of Red List category
This species has a large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence under 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 size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.
Population justification
The global population size has not been quantified, but this species is described as 'common but patchily distributed' (Stotz et al. 1996). It has been asserted that this species has undergone a severe decline across most of its range (Williams 2012); however, this view has been challenged with observations that it is still locally very abundant and not likely to be significantly threatened by human activities (F. Angulo in litt. 2013, A. More in litt. 2013). The apparently nomadic nature of this species makes assessments of its population trend very difficult. In the absence of clear evidence for a decline or substantial threats, the population is suspected to be stable.
