This is a list of the bird species recorded in Uruguay. The avifauna of Uruguay has 475 species, of which five have been introduced by humans and 46 are rare or accidental. Eighteen 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 Clements Checklist of Birds of the World'', 5th edition. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts found in each family account. Introduced and accidental species are included in the total counts for Uruguay. The following tags have been used to highlight certain 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 Uruguay * (I) Introduced - a species introduced to Uruguay as a consequence, direct or indirect, of human actions __NOTOC__ ==Rheas== Order: StruthioniformesFamily: Rheidae The rheas are large flightless birds native to South America. Their feet have three toes rather than four which allows them to run faster. One species has been recorded in Uruguay. *Greater rhea, ''Rhea americana'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of birds of Uruguay」の詳細全文を読む スポンサード リンク
