A young osprey snaps for the finger of Master Sgt. Brandon Hess, superintendent of Air Combat Command’s Maintenance Training and Course Development program, at Langley Air Force Base, Va., July 22, 2013. By running a finger along the breastbone of an osprey, a researcher can gauge the general health and diet consistence of the bird. (U.S. Air Force photo by Staff Sgt. Jarad A. Denton/Released)
