The bird fauna of the Azores is still rather poorly known, and written information on the subject are scattered in various foreign books and publications, as well as in many local and lesser known papers.

Earlier published bibliographies can be fond in David and Mary Bannermans Birds of the Atlantic Islands 1966, and in Ornithological Bibliography of the Azores published by Gerald le Grand and Duarte Furtado 1982.

This ornithological bibliography focus on published first hand information, and will not include articles merely published on the Internet, or second hand data like "recent sightings" published in mail-groups like Noticiário Ornitológico or journals like Birding World, Birdwatch, British Birds, and Dutch Birding. References from those are however found in the detailed rarity lists.

The purpose is to present a searchable data base covering all articles published about ornithological issues concerning the Azores. This will also include articles, although not primarily focusing on birds, dealing with important bird localities and bird habitats on the Azores.

One of the advantages about a data base on the Internet is that everybody can contribute to make the list of publications as complete as possibly. We have therefore chosen to publish this list even though we are aware of the fact that many articles still are missing. We hope that you will help us to complete the list, and mail us any additions and corrections needed.
