The Crimson-rumped Toucanet is not the only species of Aulacorhynchus toucanet whose rump is red - but it is the only red-rumped member of the genus in northern South America, because of this, it is unlikely to be confused with any other members in its genus. Crimson-rumped Toucanets are fairly common in humid montane forest from southwestern Venezuela south to southwestern Ecuador. A noisy, inquisitive, social bird, this species is usually found in pairs or small groups foraging for fruits, invertebrates, small vertebrate prey in the canopy.
