List of Puerto Rican birds

This is a categorized list of the bird species recorded in the archipelago of Puerto Rico which consists of the main island of Puerto Rico, two island municipalities off the east coast (Vieques and Culebra), three uninhabited islands off the west coast (Mona, Monito and Desecheo) and more than 125 smaller cays and islands. The avifauna of Puerto Rico include a total of 349 species, of which 166 (48%) are accidental, 42 (12%) are introduced by humans and 16 (5%) are endemic. Around 120 of these species breed in Puerto Rico while the majority of the others overwinter in the archipelago. This list does not include extinct species.

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, 2016 edition. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts found in each family account. Introduced, accidental and extirpated species are included in the total species counts for Puerto Rico.

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 common occurring native species.

Order: Anseriformes   Family: Anatidae

Anatidae includes the ducks and most duck-like waterfowl, such as geese and swans. These birds are adapted to an aquatic existence with webbed feet, bills which are flattened to a greater or lesser extent, and feathers that are excellent at shedding water due to special oils.
