This is a list of the bird species recorded in Micronesia. The avifauna of Micronesia includes a total of 225 species, of which 18 are endemic, 13 have been introduced by humans, and 88 are rare or accidental. 18 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 Clements's 5th edition. The family accounts at the beginning of each heading reflects this taxonomy, as do the species counts found in each family account. Introduced and accidental species are included in the total counts for Micronesia.
The following tags have been used to highlight certain relevant categories. The commonly occurring, native, species do not fall into any of these categories.
