This is a revised edition of a widely praised guide to the birds of the largest of the Caribbean islands and the neighboring Virgin Islands. It includes detailed accounts of all 284 well-documented species known to occur in the region, 273 being illustrated. The book also contains specific sections entitled "Biogeography" and "Conservation" to foster an appreciation of the uniqueness of the region's wildlife and to develop an awareness of local conservation issues. The section "Places to Bird" will help make the stay of short-term visitors more productive. The book also substantially updates the data on avian distribution and abundance in the region covering records through November 1988. From reviews of the first edition: "This well-illustrated volume is a must for any student of birds visiting Puerto Rico or the Virgin Islands. "--Chandler S. Robbins, The Quarterly Review of Biology "A valuable and informative guide. "--James A. Dick, The Wilson Bulletin "This well-written book is the first comprehensive guide to the birds of Puerto Rico and the Virgin Islands. All species, including winter visitors (which comprise 47 percent of the avifauna) are described and illustrated, making a second volume for identification of North American migrants unnecessary. . . . Aside from being a fine field guide, the book contains useful summaries of the biogeography of the region and the ecology of avian populations. . . . A major contribution is Raffaele's presentation of a wealth of hitherto unpublished information on the natural history of the region's birds. "--James W. Wiley, Ibis
