In highschool I worked at a pet food store, around 1pm everyday someone would drive behind our store dropping pet food to feed the crows. A neighbour thought we were doing it and was really upset, telling us they hated the crows and all the noise they made. Anyhow, a week or two later, I heard all the crows in the back and heard a loud 'bang'. I thought the neighbour had grabbed a shotgun and shot a crow, so I went out back to investigate. After looking around I saw that a crow laid dead next to a power transformer up on a telephone pole. At first there was one other crow cawing loudly. Then more and more crows showed up. They took turns flying up and pecking at the dead crow. Within an hour, there was probably 100 crows, in all the trees, powerlines and on apartment buildings nearby. It really impressed on me how social crows were, obviously the 'caw'ing was such that it called all the crows, and crows much have told other crows as well. You could almost say they were mourning the crow or perhaps learning how this one crow died. It would be really interesting examining the communication patterns of crows, they have such control over their voice, they must be able to do some complex communication.
