The Black-billed mountain toucan (Andigena nigrirostris), is a species of mountain toucan in the Ramphastidae family. It is found in humid highland forests in the Andes of western Venezuela, Colombia, Ecuador and far northern Peru. It is the only mountain toucan with a white throat. Despite its name, only the nominate subspecies has an entirely black bill, while both Andigena nigrirostris occidentalis and Andigena nigrirostris spilorhyncha have bills that are chestnut and black.
