Estimates of Movement and Site Fidelity Using Mark‐Resight Data of Wintering Canada Geese
Population ecologists have devoted disproportionate attention to the esti— mation and study of birth and death rates and far less effort to rates of movement. Movement and fidelity to wintering areas have important ecological and evolutionary implications for avian populations. Previous inferences a...

Population ecologists have devoted disproportionate attention to the esti— mation and study of birth and death rates and far less effort to rates of movement. Movement and fidelity to wintering areas have important ecological and evolutionary implications for avian populations. Previous inferences about movement among and fidelity to wintering areas have been restricted by limitations of data and methodology. We use multiple observation data from a large—scale capture—resighting study of Canada Geese in the Atlantic flyway to estimate probabilities of returning to previous wintering locations and moving to new locations. Mark—resight data from 28,849 Canada Geese (Branta canadensis) banded woth individually coded neck bands in the mid—Atlantic (New York, Pennsylvania, New Jersey), Chesapeake (Delaware, Maryland, Virginia), and Carolinas (North and South Carolina) were used to estimate movement and site—fidelity.
