When one crow sees another dead on the ground, it caws an alarm. Then others-five to six on average, but in rare cases as many as 60-fly in and perch on branches, cawing. In anecdotal reports, they sometimes place objects like sticks over the body as if burying it. Then they might fall silent and stare at the dead bird, almost like they're in mourning. Watching this behavior is-"moving" is not the right word. It's startling and incredible.
