title: Migration reversal: a regular phenomenon of Canada geese.
abstract: Migration from a nesting to a wintering ground and back again in autumn was detected each year during a 3-year study of individually identifiable Canada geese (Branta canadensis). Reverse migrants were primarily yearling, nonbreeding individuals and others of nonfamily status.
