context_page_description: The black-billed mountain toucan is a species of bird in the family Ramphastidae. 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 A. n. occidentalis and A. n. spilorhyncha have bills that are coloured chestnut and black.
