Acknowledgments

This report has been greatly enhanced by the observations and contributions of many birders and ornithologists too numerous to mention individually. The entire manuscript benefited from critical reviews by D. R. Bystrak, J. C. Green, C. S. Robbins, S. D. Robbins, and D. D. Tessen. Individual sections of the manuscript were critically reviewed by B. A. Moss (waterfowl), K. H. Dueholm, and J. W. Richardson (habitats). Additional suggestions and comments on various portions of the manuscript were provided by H. F. Duebbert, C. L. Henderson, R. L. Hine, D. H. Johnson, H. A. Kantrud, and R. L. Kologiski. Publication of these data was originally proposed by E. Lanis.

The staff of the Northern Prairie Wildlife Research Center contributed in many ways. R. L. Duval and C. W. Shaiffer prepared the figures. E. K. Bartels provided extensive bibliographic support.
