Taxonomy and systematics
See also List of Ramphastos species and subspecies.
Extant species
The genus Ramphastos has eight species considered to belong to the genus:
Former species
Some authorities, either presently or formerly, recognize additional species or subspecies as species belonging to the genus Ramphastos including:
Description
This genus comprises the largest toucans, ranging from 42 to 61 centimetres (17 to 24 in) in length. All have black wings, tails and thighs, but the colour of the remaining plumage depends on the exact species involved.
Distribution and habitat
They are essentially resident birds, but may take part in minor, local movements (e.g., to lower altitudes in the winter).
Breeding
They are arboreal and nest in tree holes laying 2–4 white eggs.
Food and feeding
All the species are basically fruit-eating, but will take insects and other small prey.
Threats
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.
