Well, how about "pack" or cooperative foraging by Toque macaques of Sri
Lanka. They spread out through a forest looking for ephemerally fruiting
trees. The trees bear lots of fruit--too much for one monkey--and when a
monkey finds a fruiting tree it makes a special call. The other monkeys
respond and the entire troop--mostly related individuals-- feeds.
Wolfgang Dittus has described this communal behavior.
