Population justification: The most recent population estimate is of 1,694 individuals in 2018 (ICMBio 2018). A study in 2010 found that 20.3% of individuals were reproductively active (Pacifico et al. 2014). The population is therefore placed in the band 250-999 mature individuals.

Trend justification: The species underwent a long-term historical decline due to trapping, but population estimates remained fairly stable following its rediscovery in the wild in 1978 until the mid 1990s, when numbers began to increase rapidly. While this may partly reflect improvements in survey methodology, there also has been a genuine population increase owing to intensive conservation efforts.
