List of birds of Palau
This is a list of the bird species recorded in Palau. The avifauna of Palau include a total of 149 species, of which ten are endemic, three have been introduced by humans and seventeen are rare or accidental. Three 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 Palau.
The following tags have been used to highlight several categories. The commonly occurring native species do not fall into any of these categories.
- (A) Accidental - a species that rarely or accidentally occurs in Palau
- (E) Endemic - a species endemic to Palau
- (I) Introduced - a species introduced to Palau as a consequence, direct or indirect, of human actions
