Population justification: Partners in Flight estimated the population to number fewer than 50,000 individuals (A. Panjabi in litt. 2008), thus it is placed in the band 20,000-49,999 individuals here.
Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
