This Tiny Songbird Rolls Its Head to Break Its Victim’s Neck

Shrikes kill mice by repeatedly biting the weak point at the base of their necks.

These guys are called butcherbirds because, in addition to THAT, they impale their dead prey (insects, lizards, small mice, etc) on thorns or barbed wire. This is partially to store it out of reach of thieves, partially so they can keep it on the thorn and pull it apart to more easily swallow it.
