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 parents are both active in raising the young. The white eggs are laid in a high unlined tree cavity. There is a gestation period of 18 days, and the parents both incubate for 15 to 16 days. However, they can be impatient sitters, often leaving their eggs uncovered for hours at a time. Newborn toucans remain in the nest after hatching.
