This Bald Eagle watched ducks with me at Wells Lake, just west of Faribault, Minnesota, last Sunday. It is hard not to be impressed with these large raptors, and I have posted accounts of these eagles on many occasions. The dark splotches on this bird's head indicate that it is just over 4 years old. In the next year, the head will molt into bright white heads and the body will become black.
Suffice to repeat here that the recovery of our Bald Eagles is one of our most successful conservation stories (Buehler 2001). After being listed under the Endangered Species Act of 1973, populations have dramatically increased. During this time, DDT levels have dropped and human persecution has decreased. They now breed in all Canadian provinces and every American state except Rhode Island and Vermont.
