Bird Populations is an entirely electronic annual journal of dynamic global avian demography andbiogeography that publishes original research and review papers dealing with changes in thenumbers, demographics, distributions, and ecological relationships of birds. Papers providingdocumentation of quantitative changes in bird populations or distributions are preferred, butpapers providing baseline population or distribution information are also acceptable. Papersdescribing or evaluating field techniques or analytical methods for assessing population anddistribution changes are also welcome. Contributions are encouraged from throughout the worldfrom both well-known and little-studied avifaunas. Bird Populations is published in English withabstracts in Spanish. Bird Populations can be accessed free-of-charge at www.birdpop.<strong>org</strong>.Authors should submit one complete, double-spaced, electronic copy of each manuscript, inEnglish, to: David G. Ainley, Editor, Bird Populations, dainley@penguinscience.com. Please contactDavid G. Ainley at H.T. Harvey and Associates, 983 University Avenue, Bldg D, Los Gatos, CA95032, if you are unable to submit an electronic copy. Guidelines for preparing and submittingpapers to Bird Populations, including the format for literature citations, are similar to those of TheCondor and Studies in Avian Biology. Authors are urged to examine a recent volume of BirdPopulations and follow the niceties of the journal's style. All research papers and review articlessubmitted to Bird Populations are subject to peer review.Bird Populations also publishes, reprints, and provides links to reports of major avian monitoringprograms from around the world. These reports are an important focus of the journal which isintended to serve as a yearbook on the status of the Earth's birdlife by bringing together, under asingle cover, information from many widespread localities on the annual and interim changes in theabundance, demographics, and distribution of birds. We believe that publishing, reprinting, andproviding links to these reports will draw attention in a timely manner to short-term avianpopulation fluctuations that may ultimately prove to be geographically widespread or that maysignal the beginnings of longer-term trends. We hope that the dissemination of these reports willprovide ornithologists with a global informational network for addressing avian populationchanges, will encourage an integrative global approach to avian monitoring studies, will stimulatethe establishment of additional avian monitoring programs, and ultimately will aid in theconservation of global avian diversity.Any agency or <strong>org</strong>anization from anywhere in the world coordinating or conducting a long-term,standardized avian monitoring program is invited to submit an annual (or longer time period)report of that program to Bird Populations for publication or reprinting. All reports submitted fororiginal publication will undergo peer review. Please submit one complete, double-spaced,electronic copy of any such report, in English, to David G. Ainley, Editor, Bird Populations,dainley@penguinscience.com. Already published reports submitted for reprinting will not be peerreviewed, but will be screened by the Editor when first submitted with regard to the scope andscientific merit of the monitoring program and the appropriateness of the methods and analyses.Please submit electronic copies of such reports, in English, to the Editor. Bird Populations also invitesthe authors of previously published annual or interim reports of standardized avian monitoringprograms to request that we provide an electronic link to their reports. Reports to which BirdPopulations will provide a link do not need to be in English, but we ask that the authors provide anEnglish translation of the abstract or summary. Reports to which we provide links will not be peerreviewed, but will be screened by the Editor when first submitted with regard to the scope andscientific merit of the monitoring program and the appropriateness of the methods and analyses.
