Description
The red-backed shrike is named for the reddish back of the male. It has a gray head with a prominent black eye mask. The underparts are white with a pinkish tinge. The tail is black and white. The female is brown above and cream-white below with buff scalloped patterns. Juveniles are similar to females. There are three subspecies of red-breasted shrikes with minor differences in plumage coloration and distribution.
Vocalizations: Call and song
The name “shrike” is derived from an Old English word meaning “Shriek” in reference to the shrill call. The common call of the red-backed shrikes is a harsh kek kek. The song, in contrast, is warbly and melodious. Red-backed shrikes often mimic the songs of other birds.
Distribution and range
Red-backed shrikes breed in Europe and Western Asia, wintering in South and East Africa.
Habitat
Red-backed shrikes can live in a range of environments, favoring scrubby or brushy habitats with sufficient perches for hunting. They inhabit the open country, forest clearings, woodland edges, heathland, and orchards. These shrikes can also be found at high elevations. They take to similar habitat types during winter in the African savannah, grasslands, and semi-desert region.
Diet and feeding habits
Their diet comprises mainly insects and other invertebrates. They also hunt rodents, small birds, and reptiles. During winter, they may also eat plant foods such as fruits and berries. Shrikes hunt from perches. They often store food for later consumption by impaling prey on sharp thorns or wire. This practice has earned them the moniker “butcher bird.”
Nesting and breeding
Red-backed shrikes are monogamous - for the most part, at least, with only some cases of polygyny observed. Males use threatening displays to drive away potential rivals. The breeding season is in spring. The cup-shaped nest is made of plant materials such as grass, stems, roots, and lichen. It is lined with fur, moss, and other soft materials. Females lay up to six eggs which they incubate for roughly two weeks. The young can fledge anything from 14 to 20 days, depending on the weather.
Status and conservation
The red-backed shrike has a wide range, but it has become rare in parts of its range, such as in the U.K. where it was once common. The main threats to the species include habitat loss and harmful agricultural practices impacting their food supply. Nonetheless, the overall global population is still healthy, and they are classified as least concern according to the IUCN.
