A BALD EAGLE VENTURES OUT ON ANOTHER FISHING EXPEDITION OVER THE ILLINOIS RIVER BETWEEN GRAFTON AND PERE MARQUETTE STATE PARK
EAGLE FACT(S)
WILD BALD EAGLES LIVE AS LONG AS 30 YEARS, BUT THE AVERAGE LIFESPAN IS 15 TO 20 YEARS. THE FEATHERS WEIGH TWICE AS MUCH AS THE BONES. THE BONES ARE HOLLOW AND THEREFORE EXTREMELY LIGHTWEIGHT, MAKING THEM SUITABLE FOR FLIGHT.
