So, these are resident eagles at Fort Donelson along the Cumberland River in northern Tennessee. They nest in a large oak tree about 1/4 mile from this perch. There were two people at the overlook with lots of photography equipment and a lot of local history. Since this pair arrived about 12 years ago they were named after a husband and wife who lived here during the war and their son was killed in this battle (he was a confederate soldier). The man, Jack, never got over his death. So this vigilant pair were named for them. In a side note, each year the first person to spot the newly fledged eagles at the nest gets to name them.
