Effects of Weather on Breeding Ducks in North Dakota
We are grateful to the many persons who gathered field data and assisted in other
ways. Nesting studies were initiated at Salyer in 1936 by E. R. Kalmbach. Special
credit is due L. M. Kirsch, who was involved early in the Salyer studies, was
responsible for virtually all the Woodworth data, and encouraged the completion
of this report. We benefited from reviews of the manuscript by C. W. Dane, E.
A. Driver, H. F. Duebbert, L. M. Kirsch, G. L. Krapu, H. Milne, D. G. Raveling,
D. W. Sparling, D. Q. Thompson, and two anonymous reviewers.
