Abstract : It is concluded that the Whistling Swan is an important potential hazard to aircraft during spring and autumn migrations when large concentrations fly at predictable times during a relatively short period. Migration is on a narrow front 100-150 miles wide in the eastern flyway. While enroute they may encounter bad weather causing them to land in unusual stopover places or return to point of departure. Data from radio tagged swans indicate spring migration is a succession of 250 to 700 mile flights interspersed with 10 to 25 day resting periods. Local movements during the winter may be restricted or extensive--the latter is hazardous for small aircraft. Further research needs are documented. (Author)
