Taxonomy

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).

Population justification: The global population size has not been quantified, but this species is described as 'common' (Stotz et al. 1996).

Trend justification: This species is suspected to lose 26.8-40.9% 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 38.6% over three generations from 2002.
