"Aulacorhynchus" is a genus of bird in the Ramphastidae family. With a total length of 30-40 cm (12-16 in), they are relatively small toucans, and all are mainly green. All are found in humid forest and woodland in mountains, but a few also occur in adjacent lowlands. Changes in the taxonomy of "Aulacorhynchus prasinus" and "A. sulcatus" complexes have been proposed in recent years; see species articles for further on these matters.
