sentences:  An attempted capture of a great blue heron by a golden eagle resulted in the death of both birds from wounds sustained in the ensuing fight.There is at least one case in Scotland of a golden eagle dying after being “oiled” by a northern fulmar, a bird whose primary defense against predators is to disgorge an oily secretion which may inhibit the predator's ability to fly.Of natural sources of death, starvation is probably under-reported.
