This eagle photo was taken at Alma, WI. It's not unusual to see bald eagles in this area; several bald eagle pairs are year-round residents because of the nearby Mississippi River. If the river freezes over, eagles have access to fish below Alma lock and dam on the Mississippi River.
It takes five years for a bald eagle to fully mature. During that time, an immature bald eagle's feathers gradually change from motley brown and white to a totally white head and tail, with dark brown body and wing feathers, and the beak gradually changes from dark brown to yellow and the eyes from brown to light yellow.
