List of birds of Bulgaria

This list of birds of Bulgaria includes all bird species which have been seen in the country. 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 Bulgaria. It includes 436 bird species.

The varied natural habitat, relief and climate and relatively untouched environment are among the main reasons for the many bird species in the country. The numerous islands and wetlands along the Danube including the Persina Natural Park and Srebarna Nature Reserve, as well as the lakes and swamps along the Bulgarian Black Sea Coast, support many species of diving and aquatic birds such as ducks, swans, pelicans, grebes, spoonbills and many others. The eastern Rhodopes are among the strongholds of birds of prey in Europe, with most of the species in the continent nesting in that area. The mild climate in the extreme south offers good conditions for many Mediterranean birds as well as for wintering species from the north.

The following tags highlight several categories of occurrence other than regular migrants and residents.

• (A) Accidental - a species that rarely or accidentally occurs in Bulgaria (also called a vagrant)
• (I) Introduced - a species introduced to Bulgaria as a consequence, direct or indirect, of human actions
• (Ex) Extirpated - a species no longer found in Bulgaria but found elsewhere
