A BALD EAGLE HEADS OUT IN SEARCH OF FOOD OVER THE MISSISSIPPI RIVER AT LOCK AND DAM NO. 25 NEAR WINFIELD, MISSOURI.
EAGLE FACT(S)
MIGRATING EAGLES FLY DURING THE DAY AT SPEEDS AVERAGING 30 MILES PER HOUR. EAGLES MIGRATE BY SOARING. SOARING IS ACCOMPLISHED WITH VERY LITTLE WING-FLAPPING, ENABLING THEM TO CONSERVE ENERGY. TO SOAR, EAGLES USE THERMALS, WHICH ARE RISING CURRENTS OF WARM AIR, AND UPDRAFTS GENERATED BY TERRAIN. FOR LONG-DISTANCE MIGRATION, EAGLES CLIMB HIGH IN A THERMAL, THEN GLIDE DOWNWARD TO CATCH THE NEXT THERMAL, WHERE THE PROCESS IS REPEATED.
