I have never seen one eat a deer, but Oklahoma State University owns a lake about 12 miles west of Stillwater, I live about 1/2 mile from the west side of the lake and I guess they have put some pairs of bald eagles out there. I was coyote hunting last year and was able to throw my binocs up on one flying, wow what a bird. This past fall I was riding in the pasture behind my house and I am pretty sure I saw another one flying didnt have my binocs to be 100 percent sure but I dont know what else looks like that. From what I hear in the classrooms I guess that some of the eagles have moved to a smaller lake near the lake that OSU owns, its a pretty cool deal I guess.
