The taxonomy of this list adheres to James Clements' Birds of the World: A Checklist, 2022 edition. Taxonomic changes are on-going. As more research is gathered from studies of distribution, behaviour, and DNA, the order and number of families and species may change. Furthermore, different approaches to ornithological nomenclature have led to concurrent systems of classification (see Sibley-Ahlquist taxonomy).
