Great Grey Shrike

Butcher bird

Shrikes are called “butcher birds” for their habit of impaling prey on thorns, barbed wire, and sharp twigs to create a food larder. The great grey shrike is the largest European shrike and stores a wide variety of prey — lizards, small birds, large beetles, and small mammals such as voles and shrews. The larder serves as a food store for lean periods and, in the breeding season, as a display to potential mates. The impaling also helps the shrike deal with prey too large to hold with its feet alone.

Predatory behaviour

The great grey shrike hunts from prominent perches, watching the ground below with the acute vision of a raptor. When prey is spotted, it drops in a fast, direct strike. It can take prey up to the size of a small sparrow or a large vole. In winter, it hunts in a methodical territory, working systematically through areas of rough grassland, heathland, and scrub. Site fidelity is strong — individual birds regularly return to the same wintering territory year after year.

Winter visitor to Britain

Great grey shrikes are scarce but regular winter visitors to Britain, with a few hundred individuals each year. They favour open heathland, young conifer plantations, and moorland edges. Individual birds become well-known to local birders and are often reported and re-found throughout the winter. Because they perch conspicuously, they are easier to observe than most winter visitors.

Breeding ecology

In their breeding range across boreal Europe and Asia, great grey shrikes nest in open forest edges and scrub. The male sings from high perches early in spring and the pair defends a large territory. They are among the first woodland birds to begin singing in late winter. British breeding was recorded historically but has not occurred in modern times.
