This is a list of the bird species recorded in Sint Eustatius. The avifauna of Sint Eustatius included a total of 123 species, according to Bird Checklists of the World as of July 2022.^[1] Of them, 4 have been introduced by humans.

This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 63rd Supplement, published by the American Ornithological Society (AOS).^[2] Common and scientific names are also those of the Check-list, except that the common names of families are from the Clements taxonomy because the AOS list does not include them.

The following tags have been used to highlight several categories of occurrence.

• (A) Accidental - a species that rarely or accidentally occurs in Sint Eustatius
• (I) Introduced - a species introduced to Sint Eustatius as a consequence of human actions
