Jun 16, 2011. Decorah bald eaglets branching out, soon to fledge. Nearly four months after the bald eagle mother laid her three eggs, and about 10 weeks after those eggs were hatched, the world-famous eaglets of Decorah, Iowa, are behaving as though it's time for them to leave their 80-foot-high nest and begin life on their own terms.
Well the reason that Bald Eagles have a white head and a dark brown  body is, they use thier colors to camouflage when they are hunting  for pray (like if they were in a treâ¦e) or to hide from predators  (humans).
