Abstract

Following is a summary of this three year study which was completed this summer. Periodic censuses of the population of Canada geese were made from the air and from the ground. Nesting surveys were conducted by searching the study area on foot or in a boat. Each year since 1956 (except 1959) molting geese have been trapped and banded at Turbid Lake, Yellowstone National Park, Wyoming. Data from this source were used to compute mortality and survival rates for the Jackson Hole population. In 1963 colored neck-collars were placed on 284 geese to obtain information about the timing of movements, size of the population migrating through Jackson Hole, and the breeding area of geese which molt at Turbid Lake. Hydrological data were obtained from the Bureau of Reclamation, the U.S. Weather Bureau, and the U.S. Geological Survey. Climatological data were provided by the U.S. Weather Bureau for stations at Jackson, Moose, and Moran, Wyoming. Project Number 113.
