A DISTRIBUTIONAL SURVEY OF THE BIRDS OF THE MEXICAN STATE OF OAXACA

by I,aurence C. Binford

This scholarlytreatise, culminating 30 yearsof research,is basedon field explorationand data gleaned from 17,400muscum specimens and over 400 citedreferences. Oaxaca offers a diversityof animalhabitats unsurpassed elsewherein Mexico,ranging from humid and arid lowlandtropics through subtropicalcloud forest and scrub to temperatepine-oak forest at over 11,000 feet. Eachhabitat is described,classified, depicted (28 photos),and mapped. Oaxaca'savifauna of 680 speciesexceeds that of any otherMexican state, Guatemula,or Honduras. Eachspecies account documents abundance, mode and timingof occurrenee,habitat preference, geographic and elevationul range, breedingevidence, and subspecies.An ecogeographicalanalysis of the465 breedingspecies considers barriers, corridors, and regions of endemism.Other chaptersdiscuss physiography (mapped), climate, type localities and endemic subspecies,migration, and birds of hypotheticaloccurrence (39 species).

THE AUK welcomesoriginal reports dealing with the biology of birds, emphasizing the docu- mentation,analysis, and interpretationof laboratoryand field studies,theoretical or methodological developments,or reviews of existing information or ideas. Contributionsare encouragedfrom throughout the world, but must be written in English. SUGGESTIONS TO CONTRIBUTORS. Submit the typewritten original and two copiesof the text, tables,and all other materialto the Editor.Every manuscriptmust be accompaniedby a letter of transmittal (1988, Auk 105:803). Three copiesof illustrationsshould be submitted.All typewritten materialmust be double-spacedon one side of numbered 8• x 11 inch (21• x 28 cm) good quality bond paper, with at least 1 inch (2• cm) margins. Originals typed on erasable, light weight, or mimeo bond will not be considered,but copiesmay be clear reproductions.Number pagesthrough the Literature Cited. Avoid footnotes.The style of manuscriptsshould conform to general usagein recent issues.A cover page should contain the full title, a shortened version of the title (not to exceed35 charactersin length) for use as a running head, and your addressat the time the research was conducted.Your present address,if different, should be given at the bottom of the first text page.The coverpage should include the name and full addressof the individual to whom proof is to be sent. Eacharticle should be precededby an Abstractnot exceeding5% of the length of the paper. The Abstractshould recapitulatethe findings of the paper, not describethe work done. Acknowledg- ments should follow the text and precede the Literature Cited. Scientific and English names of birdsalways should be given where first mentionedin the text, and shouldfollow TheA.O.U. Check- list of North AmericanBirds and supplementsor the appropriateequivalent unless departures are explained and defended. SI metric units should be used in all measurements.In general, abbrevi- ations of statisticalterms and mensuralunits should conform with the Council of Biology Editors' CBEStyle Manual, 5th ed. Use the 24-hour clock (0800 and 2030) and "continental"dating (1 July 1971). Tables,which must not duplicate material in either the text or illustrations, are typewritten (double-spacedthroughout!) separately from the text. Eachtable shouldcontain a short but com- plete heading, and must not contain vertical rulings. Illustrations(including labels of coordinates) should be on 8• x 11 inch (21•,• x 28 cm) sheets, and must be mailed flat. The name of the author and the figure number should be penciled on the backof each figure. Legends should be typed consecutively(double-spaced) on a separatepage. Drawings shouldbe drafted with undiluted india ink, and be large enough to permit % to •6 reduction to the size that they will appear in print. Graphsmay be drafted on coordinatepaper ruled with light bluelines; do notuse coordinatepaper ruled with greenlines. Use mechanicallettering, pressuretransfer letters, or calligraphy;typewrit- ten lettering is not acceptable.Lettering should be large enough to be easily readableafter 70% reductionof the figure, but not overly large. Lettering style should be uniform among all figures for a manuscript,as should the size of lettering following reduction.Photographs should be glossy prints of good contrastand sharpness,and should be approximatelythe same size as they will appearin print. Lettersand arrowson photographsare bestapplied by pressure-sensitivematerials. The Auk is published in a double-columnformat; give careful attention to designing your tables and illustrations accordingly. Literaturecitations for all manuscriptsare listed (double-spaced!)in a LiteratureCited section following the text and Acknowledgments.Text citations should include author and year (e.g. Darwin 1858),or, if more than two authorsare involved,the first authorand year (Joneset al. 1947). If critical matter is cited or quoted directly from longer works, indicate the pertinent pages (e.g. MacArthur 1972: 204). Citations of two or more works on the same topic should be cited in chronologicalorder (e.g. Meanley 1971, Dyer 1975). For abbreviationsand forms of titles of serial publications,follow the BIOSIS List of Serials.Consult recent issuesof The Auk and the CBE Style Manual for additional details. A more detailed set of instructions for contributors appeared in The Auk, Vol. 105, No. 1 (January1988}, copies of which are available from the Editor. Bioacousticians
