List of birds of Uruguay



This is a list of the bird species recorded in Uruguay. The avifauna of Uruguay has 501 confirmed species, of which nine have been introduced by humans, 76 are rare or vagrants, and four are extirpated or believed extinct. An additional eight species are hypothetical (see below). None are endemic.

Unless an entry is cited otherwise, the list of species is that of the South American Classification Committee (SACC) of the American Ornithological Society. Entries from other sources are not included in the above counts. The list's taxonomic treatment (designation and sequence of orders, families, and species) and nomenclature (common and scientific names) are also those of the SACC.

The following tags have been used to highlight certain categories of occurrence.


 * (V) Vagrant – a species that rarely or accidentally occurs in Uruguay
 * (H) Hypothetical – a species recorded but with "no tangible evidence" according to the SACC
 * (I) Introduced – a species introduced to Uruguay as a consequence, direct or indirect, of human actions
