Boatbill belongs to a specific bird species, commonly called a "boat-billed heron." It is a medium-sized waterbird that primarily inhabits the wetlands of tropical regions in Central and South America. Currently, there are no synonyms for "boatbill," which is a unique term reserved only for this species. However, it is worth mentioning that there are other fascinating bird species with boat-shaped bills that are, nevertheless, distinct from the boat-billed heron. For example, the boat-tailed grackle, boat-billed flycatcher, and boat-billed egret, all share a similar feature but are different bird species with different characteristics.
