Population justification: There are no population density figures and rigorous national or global population estimates are lacking. Consequently, the global population has not been determined with precision. Ferguson-Lees and Christie (2001) stated that the population was most unlikely to exceed three figures, however even though the species occurs at low densities it has an extremely large range and this estimate seems implausibly low. The population is therefore preliminarily estimated to lie in the range 1,000-2,499 mature individuals. This equates to 1,500-3,749 individuals in total, rounded here to 1,500-4,000 individuals. The population in Colombia is estimated to number c.50 mature individuals (Renjifo et al. 2014) whilst the population in Venezuela was estimated to be 300-500 mature individuals and declining in 2015 (Sharpe and Lentino 2015).
Trend justification: The population is suspected to be in decline throughout its range (C. J. Sharpe in litt. 2016) owing to ongoing habitat destruction and unsustainable hunting.
