Like most other shrikes, it has a distinctive black "bandit-mask" through the eye and is found mainly in open scrub habitats, where it perches on the tops of thorny bushes in search of prey. Several populations of this widespread species form distinctive subspecies which breed in temperate Asia and migrate to their winter quarters in tropical Asia. They are sometimes found as vagrants in Europe and North America.
In 1747 the English naturalist George Edwards included an illustration and a description of the brown shrike in the second volume of his A Natural History of Uncommon Birds. He used the English name "The Crested Red, or Russit Butcher-Bird". Edwards based his hand-coloured etching on a specimen that had been sent from Bengal to the silk-pattern designer Joseph Dandridge in London. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the brown shrike with the other shrikes in the genus Lanius. Linnaeus included a brief description, coined the binomial name Lanius cristatus and cited Edwards' work. The specific epithet is Latin meaning "crested" or "plumed".
