CROWS AND RESPONSIBILITY

When a flock of crows invades a field of corn, the birds customarily station two sentries in a nearby tree to keep watch and warn the rest of any danger. Once, two people succeeded in sneaking up on a flock of crows and scaring them before the sentries had given warning. The birds burst into flight, immediately attacked and killed the two sentries, and then flew off. The irresponsibility of those sentries could have cost the entire flock their life.
