Many people have contributed to the success of both the BBS and the development of this Home Page. Chan Robbins developed the survey, and has played a major role in maintaining it over time. Paul Geissler developed the trend analysis procedure, and Bill Link has extended the methods in recent years. Edith Thompson designed the BBS logo, and Barbara Dowell contributed the photograph of Chan Robbins. Paul Keywood provided important assistance with graphics and scanning. Brett Hoover runs the server, and provides valuable advice on how to make things work. Many people have peer-reviewed aspects of the home page. We particularly thank Deanna Dawson, Mike Erwin, Gregory Gough, Chan Robbins and Marcia Wilson for comments, reviews, and other contributions.

Finally, we thank the BBS volunteer observers, who have donated their time and effort to monitoring North American Birds. We hope that this Home Page is evidence that their efforts provide vital support for bird conservation.
