Birds of the Baja California Peninsula: Status, distribution, and taxonomy

Birds of the Baja California Peninsula: Status, Distribution, and Taxonomy. By Richard A. Erickson and Steve N. G. Howell (Eds.). American Birding Association Monographs in Field Ornithology No. 3, Colorado Springs, Colorado. 2001: 261 pp. ISBN: 1878788396. $39.95 (paper). This volume is a collection of eight papers and five appendices on the status and distribution of the birds of Baja California. In the preface, the editors lament the end of an era of "frontier" birding in Baja California brought on by the publication of this volume. While discoveries of new species are certain to decline with time, I suspect that interest in birding and ornithology in Baja California will be enhanced by the information contained in this book. Perhaps the "frontier" era that Erickson and Howell lament the end of is the unbirded, wide open spaces and the chance for making new discoveries.

Hummingbirds of North America

Hummingbirds of North America. By Sheri Williamson and John W. Vanderpoel. Peregrine Video Productions, Niwot, Colorado. 2004: 178 minutes. VHS $34.95, DVD $39.95.—This video is the third in the Advanced Birding Series by Peregrine Video Productions, following the two videos on gull identification. The format will be familiar to those who have seen the gull videos, with Jon Dunn providing the narration and acting as a personal guide throughout the video. I particularly enjoyed Jon's asides on such subjects as how the vocalizations of an Anna's Hummingbird ( Calypte anna ) sound like a “familiar” typewriter to him—before he acknowledges that the typewriter is not as familiar as it once was. The identification information is commensurate with that presented in the gull videos, although the editing and overall presentation of the information is perhaps more polished.
