Acknowledgments

My grateful thanks to the late Leslie M. Tuck for introducing me to the study of shorebirds in Newfoundland and lower James Bay in 1965, and to Andrew Macpherson, Graham Cooch, and David Munro for allowing that to happen. My special thanks to Philip S. Corbet and Donald R. Oliver for providing me the way to go north to study Ruddy Turnstones and Red Knots at Hazen Camp, Lake Hazen, Ellesmere I., Northwest Territories, in 1966. Philip Corbet also showed me the art of science, experimental design, and quantitative ecology, subsequently enriched by Hugh J. Boyd, Peter R. Grant, William J. Maher, Rich-ard S. Miller, and, indirectly, by Richard T. Holmes, through his outstanding studies of Dunlin at Pt. Barrow, AK. I am equally grateful to other research scientists for their exciting and stimulating discussions of arctic ecology: Douglas Savile, J. Anthony Downes, Monty Wood, and Robin Leech of the Entomology Research Institute (Agriculture Canada, Ottawa); and W. Earl Godfrey and Stuart D. MacDonald of the National Museum of Canada (Ottawa). More recently, I thank Cheri L. Gratto-Trevor, Brian Harrington, Peter Hicklin, Guy Morrison, Theunis Piersma, Janet Williams, Jean Sealy, and Dawn Taylor-Prime for abundant help with literature searches and Alan Poole for his continual support and encouragement during the write-up of this account. Special thanks to Guy Morrison for providing unpublished measurements of turnstone eggs (from Alert, Ellesmere I., and Rowley I., Foxe Basin) and responding to my numerous requests for copies of certain shorebird papers I found difficult to obtain. Pam Sinclair of the Birds of Yukon Project provided unpublished data on breeding distribution in Yukon. I also thank Hugh Boyd and Guy Morrison for critically reading this entire species account. And lastly, I thank the Institute for Northern Studies (University of Saskatchewan, Saskatoon) and the Canadian Wildlife Service (Ottawa) for awarding me Musk-ox Scholarships (1965–1967) and Wildlife Scholarships (1965–1967), respectively, and the Entomology Research Institute and Geoffrey Hatters-ley-Smith (Defense Research Board, Ottawa) for pro-viding complete logistic support at their high-arctic research station (Hazen Camp) on Ellesmere I. This species account is dedicated to the memory of George Miksch Sutton, arctic biologist and artist extraordinaire, whose words and interest in a young biologist’s researches on turnstones and knots some 35 years ago provided great encouragement and excitement.
