Taxonomic Notes:
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).
Assessment Information
Red List Category & Criteria:
Vulnerable A4cd ver 3.1
Year Published:
2016
Date Assessed:
October 1, 2016
Justification:
Based on a model of deforestation in the Amazon basin, and the species's susceptibility to hunting, it is
suspected that its population is declining rapidly over three generations, and it has therefore been
classified as Vulnerable.

Population
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.
Current Population Trend: Decreasing
Habitat and Ecology (see Appendix for additional information)
Lowland tropical forest, especially old riverbeds, late stage successional forest, and mature forest near
water. Also forages in secondary forest, edges, clearings, forest patches, pasture trees, plantations,
gardens, mangroves etc; to 1,440 m in Guyana (del Hoyo et al. 2002, Short et al. 2014). Feeds on a
diverse variety of fruits, also flowers and nectar, beetles, caterpillars, cicadas, termites, lizards, bird eggs
and birds, foraging in the canopy singly, in pairs or small groups (del Hoyo et al. 2002). Lays two-three
eggs in a deep natural cavity in a tree at 3-20 m height. The home range of a group is large, and birds
may move large distances in search of fruit (del Hoyo et al. 2002).
Systems: Terrestrial
Threats (see Appendix for additional information)
The primary threat to this species is accelerating deforestation in the Amazon basin as land is cleared
for cattle ranching and soy production, facilitated by expansion of the road network (Soares-Filho et al.
2006, Bird et al. 2011). It is also declining as a result of hunting pressure (del Hoyo et al. 2002).
Proposed changes to the Brazilian Forest Code reduce the percentage of land a private landowner is
legally required to maintain as forest (including, critically, a reduction in the width of forest buffers
alongside perennial steams) and include an amnesty for landowners who deforested before July 2008
(who would subsequently be absolved of the need to reforest illegally cleared land) (Bird et al. 2011).
Conservation Actions (see Appendix for additional information)
Conservation and research actions underway
It is found in several large protected areas, including the 30,000 km2 Canaima National Park in Venezuela
and 16,000 km2 Central Suriname Nature Reserve (Short et al. 2014). Conservation and research
actions proposed
Expand the protected area network to effectively protect IBAs. Effectively resource and manage
existing and new protected areas, utilising emerging opportunities to finance protected area
management with the joint aims of reducing carbon emissions and maximizing biodiversity
conservation. Conservation on private lands, through expanding market pressures for sound land
management and preventing forest clearance on lands unsuitable for agriculture, is also essential

(Soares-Filho et al. 2006). Campaign against proposed changes to the Brazilian Forest Code that would
lead to a decrease in the width of the areas of riverine forest protected as Permanent Preservation
Areas (APPs), which function as vital corridors in fragmented landscapes.
