Twenty-two migratory sparrows (Zonotrichia) which had returned to their winter home at San Jose, California (1962-63), after being displaced 2900 kilometers to Baton Rouge, Louisiana, in the winter of 1961-62, were then displaced the 3860 kilometers to Laurel, Maryland, during the winter of 1962-63. Six of the 22 birds returned across the continent to San Jose to be recaptured during the winter of 1963-64.
