Why Crows Hold Funerals

Someone is dead. There's a body, attended by a number of concerned and watchful figures, all in black. The lifeless corpse belongs to a crow, and the dark-garbed group congregating nearby is a gathering of its fellow crows, sometimes referred to as a "murder." That name is particularly apt in this case, as murder is what holds their attention. Their vigilance over a dead crow serves a purpose - one that's a matter of life and death, according to a new study in the journal Animal Behavior. By sticking close to a crow that was killed, other crows may improve their chances of learning about predators they need to avoid.
