Acknowledgments for Disc3

I am grateful to the staff of the Macaulay Library of Natural Sounds at the Cornell Laboratory of Ornithology, Ithaca, NY, for their generosity in allowing the incorporation of their vocalizations. Bob Grotke checked and repaired my tape recorder numerous times. Steve Pantle and especially Viviana Caro spent many hours copying vocalizations .

I am enormously grateful to Greg Budney, Director of the Macaulay Library of Natural Sounds, for hosting my visits to the Library and making it possible to use these wonderful vocalizations for this CD-ROM. I am grateful also for his enthusiastic encouragement, especially at the beginning of the project.

In addition, the following people contributed to the project by copying and sending many vocalizations and by giving vital advice: Jeremy Minns, Sao Paulo, Brazil; David Willis, London, UK; Guy Kirwan, Norwich, UK; Louis Fabio Silveira, Sao Paulo, Brazil; Paulo Boute, Cujaba, Brazil; Juan Mazar Barnett, Buenos Aires, Argentina; and Sjoerd Mayer, Enschede, Netherlands.

I am also grateful to Jeremiah Trimble, Curatorial Assistant in the Ornithology Department at he Museum of Comparative Zoology, Harvard University, and Douglas Causey, Senior Biologist at the Museum of Comparative Zoology, Harvard University, for allowing me to study the bird skins of the Museum.

I also would like to thank all the wonderful Brazilian people whose hospitality and help made traveling through Brazil so easy and interesting.

Finally David Gibson, Wrentham, MA, has spent many hours with upgrading The Birders Notebook and with editing to bring the CD-ROM into its present form. Clearly, without him this project would not have happened.
