In late 1993, two ‘artists turned naturalists’, William Lishman (USA) and Joseph Duff (USA), used two ultralight aircraft to guide 18 Canada Geese 644 km (400 mi) from Ontario, Canada, to Virginia, USA, in the first ever human-led bird migration. The flight was part of research to find out if birds could be ‘taught’ to follow safe migratory routes. A film based on Lishman and Duff’s work, Fly Away Home (Columbia Pictures), was made in 1996.
