helpful were C. P. Dau and M. H. Dick, who assisted with 
field work in 1974 and helped develop methodology. 
Others who provided field assistance were J. C. Bartonek, 
R. H. Day, T. J. Early, G. W. Elison, C. Haflinger, D. G. 
Kelleyhouse, E. P. Knudtson, T. A. and C. P. Ramsey,

K. A. Whitten. 
H. A. Hansen, R. D. Jones, Jr., F. B. Lee, and P. F. 
Springer offered particularly helpful advice during the 
study. Lee also provided information on captive geese at 
the Northern Prairie Wildlife Research Center and Am- 
chitka Island propagation facilities, had the color leg bands 
made, and provided several helpful unpublished references. 
S. J. Harbo (University of Alaska), and M. A. Spindler 
provided assistance with statistical methods and analysis, 
and J. T. Swartwood (Naval Torpedo Laboratory, Keyport, 
Washington), wrote the computer programs. 
CG. Reeve and J. T. Coffey assisted with construction of 
various buildings and equipment used in the study. J. L. 
Martin, D. Ash, J. Hursh, L. Shannon, and P. Odell pro- 
vided logistical support. 
Various drafts of the manuscript were reviewed by M. J. 
Amaral, J. C. Bartonek, C. P. Dau, B. Kessel (University 
of Alaska), D. R. Klein, W. Ladd, F. B. Lee, J. L. Mar- 
tin, P. G. Mickelson (University of Alaska), D. Money, 
J. Nelson, D. G. Reveling (University of California, Davis), 
J. Riffe, P. F. Springer, J. L. Trapp, D. L. Trauger, and
