The Crimson-rumped Toucanet is very similar in body form to the Emerald Toucanet, however there are key differences in their coloration. For a start, the beak of this Colombia species is red instead of black, with a white patch on the very base of the bill. It lacks the big purple patch of feathers on the face, but has a smaller turquoise patch by below the eye. The underparts are lighter green than the upper parts, and there is a small turquoise patch on the belly as well, which is not present on the Emerald. Like most toucans, their presence signals other species that is time to leave, as they will readily predate eggs and hatchlings, and we saw this behavior happen at the feeders in Finca Alejandría, as the feeders would empty whenever this bird approached. Also in true toucan fashion, their overall movement are slow, with spurts of fast activity.
