Due to human interference with their habitat, many migratory birds no longer fly south in winter. Lishman raised a flock of Canada geese from egg to adulthood and, using a microlight aircraft, taught them to follow him on their migratory route - they did indeed believe that he was their Father Goose. The 18 birds who took off after Lishman in his aircraft in October 1994 have since returned to his Toronto farm. The publication of this book was arranged to coincide with the release of a feature film documenting Lishman's work.
