Population justification: The total population has been estimated to be in excess of 5,000 individuals (del Hoyo et al. 2006). Estimates of population densities were 27.5 and 3.9 individuals per km² in the coastal plain and foothills respectively (with no data from the highlands) (Davidson 1996). The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
