There's a bird that impales prey on barbed wire, then decorates it to attract its mate!
The Loggerhead Shrike is a passerine bird. It is the only member of the shrike family endemic to North America.
The bird has a large hooked bill; the head and back are grey and the underparts white. The wings and tail are black, with white patches on the wings and white on the outer tail feather. The black face mask extends over the bill, unlike that of the similar but slightly larger Northern Shrik.
The loggerhead shrike is in fact a small bird. It impales it's prey (often larger than it) on branches and barbed wire, and then decorates it to attract a mate. It might seem like a cute little bird but be careful, you might not want to mess with him unless you want to be it's next decoration.
