While not an Eagle (nudges Fender) it is an ancipiter although the specific genus and species I couldn't tell you.

This shot wasn't easy to get and took about 40 minutes of watching and waiting. I only wish I had gotten this guy on his approach rather than his departure.

Taken at Stout's Point, near the USGS Geodedic Survey marker and the reported gravesite for Petit Jean, of whom the State Park is named.
