Effect of Late Seasons on Atlantic Brant Reproduction

Abstract

tions at the very start of the season rather than with influences occurring later on. This paper reports observations of brant during three nesting seasons of different weather conditions and attempts to relate these conditions to the physiology and reproductive success of the birds. This research was carried on as part of the requirements for a master of science degree at Cornell University under Oliver H. Hewitt and Ari van Tienhoven. The author is indebted to the Arctic Institute of North America, the Canadian Wildlife Service, the Conservation Foundation, the Frank M. Chapman Fund of the American Museum of Natural History, the New York Zoological Society, the Wildlife Management Institute, and the National Science Foundation for financial support of the brant studies. I am also indebted to F. G. Cooch, Canadian Wildlife Service, who offered valuable advice for the field work; Jay N. Eisenhart for assisting me during the 1956 field season; and Tooma and his family, with whom I camped during the 1957 season. Botanical specimens were identified by members of the Division of Botany at the National Museum of Canada.
