Population justification: Extrapolating observed population densities over the known breeding range resulted in a population estimate of 9,000 mature individuals (Repenning 2012).
Trend justification: The population is inferred to be declining as a result of habitat loss and capture for trade, which has already led to local extinctions in the breeding range (Repenning and Fontana 2013, ICMBio 2018). The rate of decline has not been quantified, but is suspected to be in the band 10-19% over ten years (ICMBio 2018).
