  • Rhamphastos

Ramphastos is a genus of toucans, tropical and subtropical near passerine birds from Mexico, and Central and South America, which are brightly marked and have enormous, often colourful, bills.[1]

Taxonomy and systematics[edit]

Extant species[edit]

The genus Ramphastos has eight species considered to belong to the genus:[2]

Image Common Name Scientific name Distribution
Tucano do bico verde - Araçari.jpg Green-billed toucan Ramphastos dicolorus Eastern Brazil, Pantanal of Bolivia, eastern Paraguay and far north-eastern Argentina
Ramphastos vitellinus -Brazil-8.jpg Channel-billed toucan Ramphastos vitellinus Trinidad and in tropical South America as far south as southern Brazil and central Bolivia

Former species[edit]

Some authorities, either presently or formerly, recognize additional species or subspecies as species belonging to the genus Ramphastos including:


This genus comprises the largest toucans, ranging from 42 to 61 centimetres (17 to 24 in) in length.[1] All have black wings, tails and thighs, but the colour of the remaining plumage depends on the exact species involved.

Diversity of bills[edit]

Distribution and habitat[edit]

They are essentially resident birds, but may take part in minor, local movements (e.g., to lower altitudes in the winter).[1]

Behaviour and ecology[edit]


They are arboreal and nest in tree holes laying 2–4 white eggs.

Food and feeding[edit]

All the species are basically fruit-eating, but will take insects and other small prey.[1]


The ischnoceran louse Austrophilopterus cancellosus is suspected to parasitize all species of Ramphastos toucans. Its presence has been confirmed on all species except the citron-throated toucan.[9]
