Butcher bird

Butcherbirds get their name from their gruesome way of feeding. The Grey Butcherbird'۪s mean-looking  beak gives you a clue. When they catch prey, they hang it off a branch or tree fork, or impale it on a sharp twig, and hack the meat away, just like a butcher.
Prey for this  ruthless killer is  small birds, mammals, reptiles and insects
