Taxonomic note

Ramphastos vitellinus, R. culminatus, R. citrolaemus and R. ariel (del Hoyo and Collar 2014) were previously lumped as R. vitellinus following SACC (2006) and a review by the BirdLife Taxonomic Working Group, and before then were split as R. vitellinus, R. culminatus and R. citreolaemus following Sibley and Monroe (1990, 1993).

Population justification: The global population size has not been quantified, but the species is described as generally common (Stotz et al. 1996). In the forested interior of French Guiana the species is very common; the national population is estimated at more than 80,000 pairs (Thiollay 1994, O. Claessens and V. Pelletier in litt. 2020). In Suriname, the species is very common in both primary and logged secondary forest (O. Ottema in litt. 2020).

Trend justification: The population trend has not been assessed directly. Locally, the population is described as stable (e.g. in Suriname; O. Ottema in litt. 2020); however in parts of the range the species is reportedly becoming scarce, likely as a consequence of trapping pressure (S. Bruslund in litt. 2022). Overall, due to the species's preference for undisturbed forests and the reports of the species becoming rarer as a consequence of hunting and trapping, the population is inferred to be in continuing decline.
Tree cover within the range is lost at a rate of 4% over three generations (17.2 years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). While the species is described as being less common in logged forests, it also occurs near forest edges, clearings and in small forest patches in savanna (del Hoyo et al. 2002); therefore, habitat loss is unlikely to drive a significant population decline. The impact of hunting and trapping on the population size has not been quantified; however overall, the impacts are likely not large due to the remoteness and inaccessibility of large parts of the range. Locally, declines may be higher in areas of gold mining and logging operations and near settlements due to hunting and trapping pressure (O. Ottema in litt. 2020). Tentatively, population declines are here placed in the band 1-19% over three generations, but an accurate quantification of the population trend is required.
