# List of birds of Paraguay

This is a list of the bird species recorded in Paraguay. The avifauna of Paraguay has 694 confirmed species, of which two have been introduced by humans, 39 are rare or vagrants, and five are extirpated or extinct. An additional 27 species are hypothetical (see below). None are endemic. An additional vagrant species is added from another source and is not included in the above counts.
Except as an entry is cited otherwise, the list of species is that of the South American Classification Committee (SACC) of the American Ornithological Society. 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 unless noted otherwise. Capitalization within English names follows Wikipedia practice, i.e. only the first word of a name is capitalized unless a place name such as São Paulo is used.
The following tags have been used to highlight certain categories of occurrence.
* (V) Vagrant - a species that rarely or accidentally occurs in Paraguay
* (E) Endemic - a species endemic to Paraguay
* (I) Introduced - a species introduced to Paraguay as a consequence, direct or indirect, of human actions
* (H) Hypothetical - a species recorded but with "no tangible evidence" according to the SACC
