THE PALOMARIN HANDBOOK PRBO's Landbird Procedures Manual Version 14 2012 THE PALOMARIN HANDBOOK ~ PRBO's Landbird Procedures Manual ~ Fourteenth Edition COPYRIGHT 2010 PRBO Contribution Number 588 [original edition] PRBO Conservation Science (founded as the Point Reyes Bird Observatory) 3820 Cypress Dr. #11 Petaluma, CA 94954 www.prbo.org This handbook is dedicated to the Palomarin Interns of 1979 and 1980 who had to do without the help of a handbook. These interns were Geoff Geupel, Kathy Keane, Janet Kjelmyr, Tom Pogson, Peter Pyle, David Sherman, and Ken Warheit. Their creativity, dedication, and constant comments and suggestions made it happen. In particular we acknowledge Janet Kjelmyr who had the perseverance to see it through. “At first glance, the work described in this handbook might seem overwhelming. It is not. The work is hard, but certainly rewarding, and we are sure that your experiences here will be educational as well as enjoyable.” – Spring 1980 Volunteers We are especially grateful to David DeSante, who co-authored the first edition with the 1979/80 interns and whose vision provided the groundwork for Palomarin. Since the original edition, many biologists have helped to shape the “handbook” into its current form. In particular, Denise Hardesty, Anne King, Maureen Flannery, Dennis Jongsomjit, and Diana Humple played critical roles. Additionally, several others have made and continue to make important contributions including Grant Ballard, Daniel Barton, Renee Cormier, David Cothran, Thomas Gardali, Heather Gates, Sue Guers, Sacha Heath, Aaron Holmes, Scott Jennings, Michael Lynes, Christopher McCreedy, Melissa Pitkin, Libby Porzig, Lars Pomara, Miko Ruhlen, Sandy Scoggin, Stacy Small, and Diana Stralberg. It is likely that many others have helped improve the handbook over the years and we sincerely apologize to those of you we forgot. Like past revisions of the handbook, this version updates data protocols as necessary. In addition to these updates, an effort was made to make the writing more clear and concise. Because the handbook has gone through so many revisions, from so many people, for over two decades, we have decided not to list authors. This handbook is truly a collective work and is always a “work in progress.” All [people] are [siblings], we like to say, half-wishing sometimes in secret it were not true. But perhaps it is true. And is the evolutionary line from protozoan to Spinoza any less certain? This also may be true. We are obliged, and bitter though it may be for some to hear, that all living things on earth are kindred. Edward Abbey 1 You have agreed to aid in a program of scientific research on the population biology of landbirds. The data that you will be helping to collect will contribute to increase our understanding of the natural world, to the advancement of science, and to the conservation of species and habitats. It is important that your data are ACCURATE AND COMPLETE. Collecting and recording data in a standardized way is the backbone of any monitoring program. Adherence to the methodology in this handbook ensures the integrity of the Palomarin Data, past, present, and future. If you have any questions, or are unsure of identification, measurement, or procedure, please ask. Communication is essential to all biological research. 2 TABLE OF CONTENTS INTRODUCTION ...................................................................................... ERROR!
