Loren Eiseley in his book...
Loren Eiseley in his book, The Immense Journey, records an incident of tramping through the woods one day until he came to the edge of a clearing where he decided to take a rest. He was more tired than he realized and soon fell sound asleep. When he awoke he had a sense of danger around him. On the limb of a nearby tree an enormous raven had a squirming nestling in his beak. The nestling's parents flew helplessly around in circles expressing their outrage. The raven was indifferent to their pleas and gulped down the nestling. The other birds took up the cry against this killer.
