The avifauna of Fiji is the richest in West Polynesia. Numerous families reach the farthest east of their range, and the island is home to several endemic species and genera, as well as sharing several more endemics with its close neighbours Tonga and Samoa.
The birds of Fiji have been heavily impacted by the arrival of humans. Several species (and some genera) were lost in prehistory and are known only from fossil remains. Other have become extinct more recently, and some species remain very close to extinction. It is certain that the current knowledge of the previous ranges of many species is incomplete and further research is needed.
This is a list of the bird species recorded in Fiji. The avifauna of Fiji include a total of 179 species, of which 31 are endemic, and 13 have been introduced by humans. Numerous species listed have been extirpated from Fiji.
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, 2022 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 Fiji. There are also a few species listed that have been recorded in Fiji, but not known to what specific island they were recorded at.
The following tags have been used to highlight several categories.
- (V) Vagrant - a species that rarely or accidentally occurs in Fiji
- (B) Breeder - a species that breeds in Fiji
- (M) Migrant - a species that regularly migrates to Fiji
- (P) Passage migrant - a species that neither breeds nor winters in Fiji but regularly passes through
- (I) Introduced - a species introduced to Fiji as a consequence, direct or indirect, of human actions
- (X) Extirpated - a species that no longer occurs here although populations may exist elsewhere
- (*) Endemic - a species that is endemic to Fiji
- (?) Uncertain - a species with uncertain records or current status
