Do ravens and crows migrate in murders?

Ravens and crows are not known to migrate in large groups called murders. Murders are typically associated with groups of crows, but their migration patterns are different. Ravens and crows are resident birds in many areas, meaning that they do not generally migrate long distances. However, some populations of ravens and crows do undertake seasonal movements, such as altitudinal or latitudinal migrations, in response to changing food resources, weather conditions, and breeding opportunities. These movements typically involve smaller groups or individual birds rather than large "murders."
