Ardeola: International Journal of Ornithology is the scientific journal of SEO/BirdLife, the Spanish Ornithological Society. The journal had a regional focus when it was first published, in 1954. Since then, and particular during the past two decades, the journal has expanded its thematic and geographical scope. It is now a fully international forum for research on all aspects of ornithology. We thus welcome studies within the fields of basic biology, ecology, behaviour, conservation and biogeography, especially those arising from hypothesis-based research. Although we have a long publication history of Mediterranean and Neotropical studies, we accept papers on investigations worldwide.

Each volume of Ardeola has two parts, published annually in January and July. The main body of each issue comprises full-length original articles (Papersand Review articles) and shorter notes on methodology or stimulating findings (Short Communications). The publication language is English, with summaries, figure legends and table captions also in Spanish. Ardeolaalso publishes critical Book Reviewsand PhD-Dissertation Summaries; summarising ornithological theses defended in Spain. Finally there are two Spanish-language sections, Ornithological News; summarising significant recent observations of birds in Spain, and Observations of Rare Birds in Spain, the annual reports of the Spanish Rarities Committee.
