Taxonomic note
Ramphastos tucanus and R. cuvieri (del Hoyo and Collar 2014) were previously lumped as R. tucanus following SACC (2006). Prior to that, they had been split as R. tucanus and R. cuvieri following Sibley and Monroe (1990, 1993).
Often considered conspecific with R. tucanus, but differs in having distal two-thirds of bill laterally black vs deep red (3); uppertail-coverts more golden, tips sometimes orange or red (2); somewhat larger size (at least 1); slightly lower-pitched and possibly more guttural song (but this may be simply a function of larger size; ns); broad hybrid zone exists, with variably intermediate populations in Brazil from R Solimões and Rondônia E to Pará, and from S Venezuela to Mato Grosso and Goiás (1). Subspecies inca sometimes merged with nominate, with which it intergrades, but it has been suggested that it represents relict semi-stabilized hybrid population (Short and Horne 2001) between present species and tucanus, although uppertail-coverts actually redder; in the past, was at times considered alternatively a distinct species. Two subspecies recognized.

Population justification: The global population size has not been quantified, but this species is described as 'common' (Stotz et al. 1996). The population is suspected to be in decline owing to habitat fragmentation, loss of nesting cavities and hunting pressure (del Hoyo et al. 2002).

Trend justification: The population is suspected to be in decline owing to habitat fragmentation, loss of nesting cavities and hunting pressure (del Hoyo et al. 2002).
