However, the subspecies R. v. ariel is closer to R. v. culminatus than to the nominate, and are by some already considered close to distinct species status.

It looks very similar to, and has traditionally been considered part of, R. v. ariel, but molecular analysis suggests that it has been isolated for a long time and is a yet-undescribed separate subspecies or possibly even species (Weckstein, 2005).

It weighs 300–430 g (11–15 oz)[4] Wherever the distributions of the subspecies meet, individuals with features that are intermediate compared to above described races are common due to hybridization.

Other fruits which the channel-billed toucan feeds upon are those borne by Cecropia, Ficus, Hevea, Nectandra, Oenocarpus, Pourouma and Pouteria.

They will also consume papaya, mangoes, avocados and peppers if human intrusions into their habitat occur.

They have short bills and specialized pads on their heels to protect them from the rough floor of the nest.
