For more than 100 years, The Auk has published original reports on the biology of birds. As one of the foremost journals in ornithology, The Auk publishes innovative empirical and theoretical findings. Topics of articles appearing in The Auk include the documentation, analysis, and interpretation of laboratory and field studies, theoretical or methodological developments, and reviews of information or ideas. Authors are encouraged to consider the relevance of their conclusions to general concepts and theories and to taxa in addition to birds.
Along with research articles, The Auk also includes Perspectives that are invited by the Editor, Commentaries, Letters to The Auk and reviews of recently released books that are of significance to ornithologists selected by the Book Review Editor.
Perspectives are points of view expressed on a particular subject. They are normally solicited by the editor and, beginning with the January 2007 issue, are reviewed externally by at least one person, as well as by the Editor. Authors with proposals for perspectives should contact the Editor.
Letters to The Auk provide opportunities to speculate in print, comment on recent issues, topics, and methodologies, provide information of historical or taxonomic interest and comment briefly on papers published in The Auk or to respond to such comments. Letters are reviewed by the Editor and at least one outside reviewer and are published at the discretion of the Editor. Exchanges concerning published papers are strictly limited. For additional information, see Auk 123:347, 2005.
