Taxonomy

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 this species is described as 'fairly common' (Stotz et al. 1996).

Trend justification: This species is suspected to lose 13.6-22.6% of of its extent of suitable habitat in the Amazonian portion of its range over 35 years, as projected after 2002 using a model of forest loss in the Amazon basin (Soares-Filho et al. 2006). By taking the pessimistic (business as usual) scenario of forest loss and factoring in the species’s susceptibility to hunting, fragmentation and edge-effects (following Bird et al. 2011), it is suspected to decline by 32.1% over three generations from 2002.
