We continue to teach them to feed. In medieval Europe they foretold death. They would recognize approaching armies and flocks would fly ahead in anticipation of the carnage.
In the times to come, these birds may be our harbingers and beacons. Watch carefully and they may serve as guides. In payment they will dine on our flesh. And pick out our eyes.
They need to learn to feed. On other things and then one day on us and then we will see again and our bodies will soar.
