Acknowledgments

(Original authors): I thank my many field assistants who, over the years, have helped collect data at Guelph, ON. Their assistance has helped provide many of the data reported above and the enhanced understanding of goldfinch biology. Research at Guelph has been supported by Natural Sciences and Engineering Research Council of Canada operating grants to the author. Sonographs courtesy of Sandra Gaunt, Borror Laboratory Bioacoustics, Ohio State University, and egg data provided by Western Foundation of Vertebrate Zoology. I thank W. Dawson, A. Poole, and P. Stettenheim for their constructive comments on an earlier draft of this account, and C. Thompson for his specific comments on molt. Lori Ferguson typed various drafts of the manuscript and arranged its successful transfer to disc.

K. McGraw: I thank G. Hill for sharing his enthusiasm for goldfinches with me and for piloting captive studies that made my subsequent work on parasites, pigments, and color much easier. K. Navara, V. Olson, R. Parker, and R. Stradi provided useful input on my goldfinch work over the years. A. Poole made several helpful suggestions to stimulate revision of particular parts of this account. I was funded by the School of Life Sciences and College of Liberal Arts and Sciences while revising this account.
