A man's neck is sliced by a swooping bird. Looks almost intentionally fake.
This movie is about a flock of homicidal birds terrorize the residents of the local city, so mild violence is guaranteed by the premise alone. Cut-and-pasted bird animations hover onscreen as actors panic and shout in pain.
In one scene, birds fly toward some people and explode (offscreen) into green acid.
Corpses are shown with blood effects from a Halloween makeup kit. These wounds only look *somewhat* realistic.
