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.
Normal flight speed going from perch to perch is much less than this. The Bald Eagle catches prey by flying low and âsnatchingâ with their feet mostly, not like ospreys or peregrine falcons that actually dive at their prey. When engaging in this âsnatchingâ behavior, they can reach speeds over 75 mph.
