Sauk Valley residents who want to watch eagles can catch a glimpse of the patriotic birds near dams and in public parks near rivers. The best time of the day to view eagles is anytime in the early morning until about 11 a.m. While viewing the birds, stay quiet and move slowly, lest you startle them. It's important not to scare the birds, as they need to conserve their energy during the winter months to stay warm. While eagles feast mostly on fish, they'll also dine on other critters, including squirrels, prairie dogs, raccoons, and rabbits.
