PAYNTER, JR. 1994 Printed in the United States of America Copyright 1994 By the President and Fellows of Harvard College INTRODUCTION TO SECOND EDITION In the 13 years since the first edition of this gazetteer, publications dealing with the ornithology of Uruguay have appeared at a rate of about three per year. These, as well as several publications that had been overlooked earlier, have been incorporated in the present edition. With the recent computerization of some major museum collections, it has become easier to discover records of birds from times and localities not yet recorded in the literature. Unfortunately, few specimens from Uruguay have reached the Northern Hemisphere and computer records have not yielded the rich lode of data uncovered for countries such as Bolivia and Ecuador. Nevertheless, these sparse data have been added to the gazetteer, making it as complete as possible at this time. A minor change in style has evolved since the gazetteer series was begun. This involves restricting entries in the bibliography to those publications directly concerned with the ornithology of a given country. Included here are titles that were not used in constructing the gazetteer. The bibliography is, therefore, a complete list of all publications dealing with the country under consideration. Data used in the gazetteer which were obtained from sources peripheral to the corpus of the given country's literature are documented in full, but within the text rather than in the bibliography. To the abbreviations and acronyms listed in the introduction to the first edition are added: ANSP: Academy of Natural Sciences, Philadelphia (data from specimens therein). BMNH: British Museum of Natural History (data from specimens therein). CM: Carnegie Museum of Natural History (data from specimens therein). UMMZ: University of Michigan Museum of Zoology (data from specimens therein). iil USNM: United States National Museum (data from specimens therein). For assistance with this edition I am grateful to James Dean, Daniel S. Cooper, Rodolfo Escalante, Lloyd F. Kiff, Storrs L. Olson, Robin K. Panza, Robert B. Payne, Christopher W. Thompson, David Willard, and particularly to Alison Pirie, who fills several essential functions in this continuing project. Raymond A. Paynter, Jr. 25 April 1994 INTRODUCTION TO FIRST EDITION This is the fifth in a series of ornithological gazetteers for the Neotropics. Like its predecessors it began as incomplete card files maintained by the Museum of Comparative Zoology and Field Museum of Natural History, and was finished after a review of all the literature on Uruguayan ornithology that we have been able to discover (see Bibliography). Unpublished data from specimens in the Museum of Comparative Zoology and the Field Museum also have been included, but, because of the impracticality and enormity of the task, not from museum specimens elsewhere. As in the past, the style of referencing employed by the United States Board on Geographic Names (USBGN) is used here (e.g., "Paso Molino" for a town but "Mazangano, Paso" for a river crossing; "Playa Brava" for a populated locality but "Malvin, Playa de" for a beach). Also, the Map of Hispanic America (MHA) is referred to whenever possible and less readily available maps only when necessary. Unfortunately, comprehensive recent maps have not been found, resulting in a large number of sites for which we have USBGN coordinates but no map references. The following abbreviations are used: Esso Map: Road map distributed by Esso Standard Oil Co. (Uruguay), S. A. (1:1,000,000), 1968. FMNH: Field Museum of Natural History (data from specimens therein). MCZ: Museum of Comparative Zoology (data from specimens therein). MDN: Republica Oriental del Uruguay (1:500,000), 1971, Ministero de Defensa Nacional, Servico Geografico Militar. MHA: Map of Hispanic America ("Millionth Map"), 1939-1940, American Geo- graphical Society, New York (reference to one of the three sheets covering Uruguay). ONC: Operational Navigation Chart (1:1,000,000), Defense Mapping Agency, Aerospace Center, St. Louis, Missouri (reference to sheet ONC Q-27, 1973, sheet ONC Q-28, 1974, or sheet ONC R-24, 1965, revised 1975). USBGN: United States Board on Geographic Names, Dept. of the Interior, Washington, D.C. (refers to Gazetteer No. 21, Uruguay, 1956). We thank students and colleagues who contributed to the original files for this gazetteer. We are also grateful to Melvin A. Traylor, Jr. for providing valuable information on specimens in the Field Museum of Natural History and for preparing the political map of Uruguay. Juan Cuello read an early draft of the manuscript and supplied several papers which otherwise would have been unavailable to us. Many thanks go to Alison Pirie for her careful preparation of the typescript from confusing card files and illegible drafts. David M. Rand Raymond A.
