The Loggerhead Shrike (Lanius ludovicianus) is a passerine bird. It is the only member of the shrike family endemic to North America; the related Northern Shrike (L. excubitor) occurs north of its range but also in the Palearctic.
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 Shrike.
