List of birds of São Tomé and Príncipe
This article includes a list of references, related reading, or external links, but its sources remain unclear because it lacks inline citations. (September 2024) |
This is a list of the bird species recorded in São Tomé and Príncipe. As São Tomé and Príncipe is a series of islands, its avifauna grows whenever a "new" species arrives or is recorded for the first time; the list comprises 176 species, of which 25 are endemic, 4 have been introduced by humans, and several are rare or accidental (often termed "vagrants").
This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) for the most part 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 São Tomé and Príncipe.
The following tags have been used to highlight several categories, but not all species fall into one of these categories. Those that do not are commonly occurring native species.
- (A) Accidental - a species that rarely or accidentally occurs in São Tomé and Príncipe
- (E) Endemic - a species endemic to São Tomé and Príncipe
- (I) Introduced - a species introduced to São Tomé and Príncipe as a consequence, direct or indirect, of human actions
