I found this on the web. I don't know if the photo is real or if the eagle was added via Photoshop, but it is an inspiring image nonetheless.
Update: the photo is real. The photo was taken by Frank Glick in Fort Snelling National Cemetery in Minneapolis, Minnesota. Glick's hobby is photography and he was visiting the cemetery when he spotted the eagle atop a veteran's gravestone. Another man who saw the photo did some research to learn the identity of the veteran on whose gravestone the eagle alighted. He learned it was Sgt. Maurice Ruch, a veteran of World War II. Ruch's widow as well as his best friend were greatly inspired by the photo when it was finally shown to them.
