Red-backed Shrike

The Red-backed Shrike is a compact, thickset songbird that punches well above its weight as a predator. Despite its small size, it hunts like a miniature bird of prey, perching conspicuously on wires, fence posts, and the tops of bushes while scanning for insects and small vertebrates.

The breeding male is unmistakable: a soft blue-grey crown and nape, a rich chestnut-brown back, and a broad black mask running through the eye, set off against pale pinkish-buff underparts. Females and juveniles are far duller, with warm brown upperparts and fine dark crescent-shaped barring across the breast and flanks, giving them a scaly appearance.

Red-backed Shrikes are famous for their habit of impaling prey items on thorns or barbed wire to create a "larder," a behavior that has earned shrikes the nickname "butcher birds."

Key field marks

• Male: grey head, black eye-mask, chestnut-red back, pinkish-white underparts, and a black-and-white tail
• Female/juvenile: brown above with dense scaly barring below, lacking the male's grey head and black mask
• Stocky build with a strongly hooked bill tip, adapted for tearing prey
• Often perches upright and alert on an exposed twig, wire, or fence post

Similar species

The male is distinctive, but females can be confused with juvenile Woodchat Shrikes or Lesser Grey Shrikes. The Woodchat Shrike shows a chestnut crown (not a chestnut back) and white wing patches, while the Lesser Grey Shrike is larger, greyer overall, with a black mask extending across the forehead.

Range

Breeds across most of Europe and temperate western Asia, from Britain and France (now rare in the far west) east to Mongolia. It is a long-distance migrant, wintering in savanna and bushland of eastern and southern Africa.

Habitat

Favors open countryside with scattered thorny bushes, hedgerows, orchards, and rough grassland where it can hunt from exposed perches. Avoids dense forest and treeless farmland alike, needing a mix of open ground for hunting and thorny scrub for nesting and food storage.

Migration

An impressive long-distance migrant, some individuals travel over 10,000 km between European breeding grounds and African wintering areas, often following a loop migration route through the eastern Mediterranean and Arabian Peninsula.

Behavior

A sit-and-wait predator, the Red-backed Shrike watches from a perch before dropping onto prey on the ground or snatching insects in flight. It caches surplus food by impaling it on thorns, spines, or barbed wire, both to store food and to make large or toxic prey easier to handle.

Voice

The song is a soft, scratchy warble that often incorporates mimicry of other bird species. The call is a harsh, chattering "chack-chack," used as an alarm.

Feeding

Diet consists mainly of large insects (beetles, grasshoppers, bumblebees) supplemented with small lizards, frogs, mice, and occasionally nestling birds, especially when feeding young.

Nesting and breeding

Builds a bulky cup nest of grass, moss, and roots low in a thorny bush. Clutches typically number 4-6 eggs, incubated mainly by the female for about 2 weeks, with both parents feeding the chicks.
