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.[1] All have black wings, tails and thighs, but the colour of the remaining plumage depends on the exact species involved.

Diversity of bills

Distribution and habitat

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

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.[1]

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.[9]
