IN ORDER TO ABSORB AS MUCH HEAT AS POSSIBLE, A BALD EAGLE AT THE SANDY ISLAND EAGLE SANCTUARY NEAR WINFIELD, MISSOURI, SPREADS ITS WINGS IN A PROCESS CALLED "THERMOREGULATING"
EAGLE FACT(S)
THE DOWN FEATHERS ON AN EAGLET PROVIDE INSULATION BUT ARE USELESS FOR FLIGHT. A YOUNG BIRD MUST HAVE ITS JUVENILE FEATHERS BEFORE ATTEMPTING ITS FIRST FLIGHT. JUVENILE FEATHERS WILL HAVE GROWN IN SOME 10 TO 13 WEEKS AFTER HATCHING.
