ACKNOWLEDGMENTS

Funding for surveys of inland-breeding waterbirds from 1997 to 1999 was provided by California Department of Fish and Game (CDFG), Chevron USA Inc., Klamath Basin National Wildlife Refuge (NWR) Complex, National Fish and Wildlife Foundation, the Richard Grand Foundation, the Weeden Foundation, U.S. Fish and Wildlife Service’s (USFWS) Division of Migratory Birds and Habitat Programs (Region 1), and from individual donors to PRBO Conservation Science (PRBO; formerly PRBO Conservation Science). Funding from USFWS for additional work on Caspian Terns contributed to knowledge of that species presented here. Funding of PRBO's research on California Gulls at Mono Lake has been provided by an anonymous donor, the Atlantic Richfield Foundation, the Conservation Endowment Fund, Golden Gate Audubon Society, the Los Angeles Department of Water and Power via Hubbs–Sea World Research Institute, the Mono Basin National Forest Scenic Area Visitors Center in partnership with the Eastern Sierra Interpretive Center, the Mono Lake Committee, the Mono Lake Foundation, National Audubon Society, Recreational Equipment Inc., USFWS, and the membership of PRBO.

This project had its roots in California Gull research initiated at Mono Lake in 1983 by PRBO. That work led to statewide surveys of California and Ring-billed gull colonies in 1994, which inspired the statewide surveys of seven key species of inland-breeding waterbirds from 1997 to 1999 that provide the basis for this catalogue. The many collaborators on this project have been invaluable, inspiring, and a pleasure to work with, and I sincerely and deeply appreciate their help in all aspects of this work.

The following individuals or groups provided valuable information, advice, help in the field, logistical support, or access to private or restricted public lands without which this study would not have been possible: Dan Airola, Chuck Alexander, Matt Alexander, Bob Allen, Jack Allen, Larry Allen, Dan Anderson, Lee Ashford, Jack Bailey, Bruce Barbour, Bob Barnes, Jenny Barnett, John Beckstrand, Ted Beedy, Doug Bell, Reuben Benavides, Nina Bicknese, Frances Bidstrup, Debbie Bliss, Steve Bobzien, Jay Bogiatto, Ken Bonesdale, Bill Bousman, Mike Brady, Steve Bruggemann, Deb Bumpus, Bureau of Land Management, Steve Burton, Tim Burton, CDFG, Dave Calleri, Central Valley Bird Club, Mark Chichester, Mike Chouinard, Beverly Clark, Danny Cluck, Howard Cogswell, Mike Cole, Laura Collins, Steve Collup, Jim Crew, Ralph Cutter, Brian Daniels, Thomas Darden, Don Davis, Adrian del Nevo, Al DeMartini, Bruce Deuel, Jan Dierks, Barbara Ditman, Leo Edson, Ray Ekstrom, Joel Ellis, Chris Elphick, Andy Engilis, Wade Epperson, Kathy Erwin, George Espino, Pete Famolaro, Elias Flores, Larry Ford, John Fredrickson, Jack Frey, Michael Fry, John Fulton, Jim Gain, Jay Dee Garr, Kimball Garrett, Dave Germano, Greg Gerstenberg, Ron Gerstenberg, Andy Gordus, Annie Graves, Frank Gray, Helen and Paul Green, Jim Hainline, Mike Hall, Bill Hamilton, Steve Hampton, Keith Hansen, Rob Hansen, Tim Hansen, David Hardt, Patrick Hendrix, Bob Herkert, Justin Hite, Kathy Hobson, Paul Hoffmann, Chuck and Barbara Holmes, Waldo Holt, Barbara Hopkins, Les Howard, Bob Huddleston, Joan Humphrey, Kevin Hunting, Craig Isola, Ron Jackman, Joseph R.

Additional individuals who assisted with nest counts at California Gull colonies at Mono Lake and San Francisco Bay over the years are too numerous to list, but still their help is greatly appreciated. Similarly, a long list of state, federal, and local land management agencies or private land owners allowed access to lands or assigned personnel to help on surveys. My sincere apologies to anyone whom I inadvertently may have failed to acknowledge here or elsewhere in the text.

Paul Fonteyn, Kevin Hunting, Dave Mauser, Gary Page, Jennifer Roth, Tom Smith, Denise Wight, and Tara Zimmerman provided support and encouragement for the project. CDFG staff Lyann Comrack, Kevin Hunting, and, especially, Paul Kelly generously arranged airplane time, and the talented pilots from CDFG Air Service’s—Wayne Burnett, Tom Evans, Lauren Goehring, Larry Heitz, Bob Morgan, and Ron Van Benthuysen—provided invaluable help on aerial surveys. Ken Blum of Tamal Sáka, Tomales Bay Kayaking, provided kayaking equipment for use on the surveys. Harry Carter, Gerry McChesney, Daryl Whitworth, and Phil Cappitolo engaged in valuable discussion during conception of the project, provided camera equipment and film for photographing colonies on aerial surveys, and were very helpful in providing facilities and training for counting seabird or waterbird colonies on aerial photographs. Lynne Stenzel gave valuable insight regarding sampling design for roadside surveys of Black Terns, and Nadav Nur analyzed the survey data. Martha Leighton of the California Agricultural Statistics Service provided data on acreage by county of planted rice in the Central Valley, and Jay Dee Garr, Cass Mutters, and Jack Williams shared insight on the timing of rice planting in 1998 and methods of rice cultivation. Jim Snowden kindly shared long-term data on Black Terns from CDFG surveys of pheasant broods in Butte County. Jeff Seay/H. T. Harvey and Associates and Rob Hansen/Hansen’s Biological Consulting and associates kindly arranged access, helped on surveys, or shared data from their surveys of evaporation ponds, associated mitigation wetlands, and the Hacienda Ranch Flood Basin and the South Wilbur Flood Area in the Tulare Basin. Rob Hansen also supplied valuable unpublished field notes of Ward B. Minturn. Additional colleagues who kindly shared unpublished data included Dawn Harris for sightings of Black Terns from surveys of seven duck brood ponds in the Sacramento Valley, Kathy Molina for numbers of Caspian Terns at subcolonies at the Salton Sea, and Pat Stackpole for numbers of Double-crested Cormorants nesting at Stone Lakes NWR. CDFG, Klamath Basin NWR Complex, and Modoc National Forest provided boat support or personnel to help on surveys. Overall, state and federal land management agencies made extremely important contributions to the success of this project. In particular, the Devil’s Garden Ranger District of Modoc National Forest provided radio and logistical support; George Studinski was especially helpful in sharing extensive information about wetlands in that area and how to navigate boulder-strewn roads to get to them.

Karen Cebra, Carla Cicero, René Corado, Krista Fahy, Kimball Garrett, Ned Johnson, Freda Kinoshita, Douglas Long, Robert McKernan, James Northern, and Philip Unitt provided data from egg sets, or confirmation of a lack thereof, from their respective institutions. Manuel Marin kindly confirmed the validity of California Gull egg sets from Stanislaus County housed at the Western Foundation of Vertebrate Zoology. Helen Green supplied data from the editors of the Middle Pacific coast region of North American Birds on file with Golden Gate Audubon Society. John Beckstrand was especially helpful in compiling data on gull numbers from the Annual Narrative Reports of the Klamath Basin NWRs, and Dave Mauser and Ken Sturm provided access to such reports and other unpublished data for various species contained in the files of the Klamath Basin and Salton Sea NWRs, respectively. Thanks to Kathy Molina, Brennan Mulrooney, Ken Sturm, and, particularly, Jennifer Roth for counting cormorant nests from slides or photographs of colonies at the Salton Sea. Grant Ballard, the Estuarine Institute, Janet Hanson, Catherine Hickey, Peter LaTourette, Mike Lynes, Lars Pomaro, Jennifer Roth, Diana Stralberg, and Dionne Wrights helped with GIS mapping, graphics, or scanning photos for figures. Ronald Beitel and David Drescher of USFWS kindly supplied the digital topographic maps used for mapping colonies. Diana Stralberg designed the digital map layout for the accompanying CD atlas of inland-breeding waterbirds in California, which greatly enhances the value of this document; Chris Rintoul performed the technical conversion of data files to produce the colony maps; and Viola Toniolo designed and executed the layout of the map text and tables for website posting and produced the statewide distribution maps. Dan Anderson, John Cooper, John Coulson, Gordon Gould, Stephen N. G. Howell, Joan Humphrey, Kevin Hunting, Joseph R. Jehl Jr., James O. Keith, Gerry McChesney, Tim Manolis, Dave Mauser, Kathy Molina, Nadav Nur, Bruce Peterjohn, Tom Ryan, Phil Unitt, Tara Zimmerman, and an anonymous reviewer provided thoughtful reviews, or shared authorship, on prior reports or papers summarizing data from this project. Dan Anderson, John Kelly, Dave Mauser, and Kathy Molina provided thoughtful reviews of the full report, and Lyann Comrack, Stephanie Jones, Nanette Seto, and Michelle Whalen provided editorial comments or assistance. Lyann Comrack and Dale Steele were instrumental in publishing the report in California Department of Fish and Game’s Nongame Wildlife Program Report Series.
