Population justification: The population size has not been quantified. Subspecies zabele is suspected to number less than 10,000 mature individuals (ICMBio 2018). While the size of the nominate subspecies noctivagus is unknown, observational records (per eBird 2022) suggest that it may be of roughly equal size. Tentatively, the overall population is therefore here placed in the band 10,000-19,999 mature individuals.
Trend justification: In the past the species was considered common, but is now described as rare and local (ICMBio 2018). Despite its tolerance of secondary habitats, population declines are attributed to habitat loss and degradation as well as the impacts of hunting (ICMBio 2018, Cabot et al. 2020). While declines in subspecies noctivagus are not thought to exceed 20% over three generations (16.1 years), subspecies zabele is suspected to decline at a rate of >30% over three generations and to suffer local extinctions (ICMBio 2018, Las-Casas et al. 2019). Tree cover within the range is lost at a rate of 13% over three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Even though the species is not strictly dependent on forests it appears negatively affected by large-scale habitat degradation (ICMBio 2018). The impact of hunting has not been quantified. Tentatively, the overall population decline is here placed in the band 20-20% over three generations.
