The researchers sequenced several nuclear and mitochondrial genes from 40 toucan species, representing all recognized subgenera within the genus Ramphastos. The study found that toucans could be divided into six distinct clades, each with different bill morphologies and geographic distributions.

The largest dimensions found in this species are an approximate head-to-tail length of 1.44 m (4.7 ft) and a wingspan of 3.65 m (12.0 ft).

The toucan beak has a network of superficial blood vessels that support the rhamphotheca, the horny sheath of the bill. [7] The toucan is able to dilate or enlarge the beak's blood vessels when temperatures rise above a thermal neutral zone to allow for blood to pass readily into the beak, allowing for heat exchange and cooling.
