This is a list of the bird species recorded in Bermuda. The avifauna of Bermuda include a total of 375 species, a remarkable number considering that the island is a mere 53.3 square kilometres. Ten of these have been introduced by humans; the mallard also occurs naturally as a non-breeding migrant. 207 are rare or accidental. Two species listed are extirpated in Bermuda; Audubon's shearwater formerly bred but is now only a vagrant while there are a few old records of Eskimo curlew occurring on migration but none since 1930. Seven species are globally threatened. This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of the American Ornithologists' Union checklist (7th edition and supplements). The species counts found in each family account reflect this taxonomy. Introduced and accidental species are included in the total counts for Bermuda. Species marked accidental are those listed as "rare" or "very rare" in Dobson (2002). The following tags have been used to highlight several categories, but not all species fall into one of these categories. Those that do not are commonly occurring native species. * (A) Accidental - a species that rarely or accidentally occurs in Bermuda * (I) Introduced - a species introduced to Bermuda as a consequence, direct or indirect, of human actions * (Ex) Extirpated - a species that no longer occurs in Bermuda although populations exist elsewhere * (E) Extinct -a species that is extinct globally __NOTOC__ ==Ducks, geese and swans== Order: AnseriformesFamily: Anatidae The family Anatidae includes the ducks and most duck-like waterfowl, such as geese and swans.
