Great grey shrike

The great grey shrike (Lanius excubitor) is a sizable, predatory songbird belonging to the shrike family (Laniidae). It is part of a superspecies with its parapatric southern counterparts: the Iberian grey shrike and the Chinese grey shrike. Both sexes share similar plumage—pearly grey upperparts, a black eye-mask, and white underparts. Breeding primarily occurs north of 50° northern latitude across northern Europe and Asia, with most populations migrating south to temperate regions for the winter. This species is carnivorous, with rodents making up more than half of its diet.

Carl Linnaeus first scientifically described the great grey shrike in his 1758 *Systema Naturae* under its current binomial name. His original Latin description read: "Lanius cauda cuneiformi lateribus alba, dorso cano, alis nigris macula alba." At that time, Linnaeus did not separate other grey shrikes—such as the lesser grey shrike—as distinct species, though some authors already did. Linnaeus’s binomial replaced earlier cumbersome names from naturalist texts; in his own *Fauna Svecica*, he called it *Lanius cinereus major*, while Johann Leonhard Frisch referred to it as *pica cinerea sive lanius major*, though his color plate mistakenly swapped male and female. Most authors Linnaeus cited—Eleazar Albin, Ulisse Aldrovandi, John Ray, and Francis Willughby—used *lanius cinereus major*, a near-literal equivalent of "great grey shrike." Linnaeus gave the type locality simply as "Europa."

The scientific name *Lanius excubitor* literally means "sentinel butcher": *Lanius* is Latin for butcher, and *excubitor* means watchman or sentinel. This references two key behaviors: storing prey by impaling it on thorns, and perching on exposed treetops or poles to scan for food. Conrad Gessner’s use of *lanius* for shrikes established the term. Linnaeus chose *excubitor* because the species "observes approaching hawks and announces [the presence] of songbirds." Falconers later used this habit, as William Yarrell recorded. The common English name "shrike" comes from Old English *scríc*, meaning "shriek," referring to its call.

Old folk names for the bird, reported by Aldrovandi, Gessner, Ray, and Willughby, mainly come from Germanic languages.
