Corvid wars extreme

The corvids are always causing disturbances or arguing about something or other. The resident crows consider themselves top of the chain and they chase off buzzards or other corvids when they stray onto their territory. For a week or so the crows have been chasing and in turn been chased by a jackdaw, who I am guessing was intending to nest here. The noise was pretty incessant. At one point the jackdaw seemed to be joined by a whole crowd of jackdaws but they didn't stay very long. Yesterday it went quiet and it wasn't long before I found the jackdaw's corpse.
