List of birds of Liechtenstein

There are 255 bird species recorded in Liechtenstein, 4 of which are globally threatened. This total includes four species introduced by humans.

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 Liechtenstein.

The following tags have been used to highlight several categories. The commonly occurring native species do not fall into any of these categories.

• (A) Accidental - a species that rarely or accidentally occurs in Liechtenstein
• (Ex) Extirpated - a species which no longer occurs in Liechtenstein, but other populations still exist elsewhere
• (I) Introduced - a species introduced to Liechtenstein as a consequence, direct or indirect, of human actions
