Shrikes (/ʃraɪk/) are carnivorous passerine birds of the family Laniidae. The family is composed of 33 species in four genera. The family name, and that of the largest genus, Lanius, is derived from the Latin word for "butcher", and some shrikes are also known as butcherbirds because of their feeding habits. The common English name shrike is from Old English scrīc, alluding to the shrike's shriek-like call. Most shrike species have a Eurasian and African distribution, with just two breeding in North America (the loggerhead and northern shrikes). No members of this family occur in South America or Australia, although one species reaches New Guinea. The shrikes vary in the extent of their ranges, with some species such as the great grey shrike ranging across the Northern Hemisphere to the Newton's fiscal which is restricted to the island of São Tomé. They inhabit open habitats, especially steppe and savannah. A few species of shrikes are forest dwellers, seldom occurring in open habitats. Some species breed in northern latitudes during the summer, then migrate to warmer climes for the winter.
