Life Trockenrasen: Red-backed Shrike

The red-backed Shrike belongs to the shrike family (Laniidae). Globally, there are 32 species of shrikes, and in Central Europe, the red-backed Shrike is the most commonly found member of this family.

Distribution

The Red-backed Shrike is a migratory bird, spending its winters in Africa and Asia. It prefers semi-open habitats rich in insects and structured with hedgerows and shrubs. Warm and dry environments, such as dry grasslands and bushy forest edges, are particularly suitable for this species.

Identification

The red-backed shrike is the smallest shrike species in Central Europe. Males are easily distinguishable from females by their vibrant colouring. Like other shrike species, they feature a characteristic black "bandit mask" across their eyes. The males have rust-brown backs and upper wings, while their heads and necks are bluish-grey. The underside is mostly whitish to cream-colored, with flanks and chests often tinted with a light pinkish hue. Females, on the other hand, have a brown eye stripe, making their eyes more prominent. Their heads and backs are reddish-brown, while the underside is beige and may display dark brown crescent patterns.

Reproduction

The red-backed shrike builds its nest in thorny bushes and hedges that provide protection from predators. Preferred nesting plants include wild rose, blackthorn, hawthorn, and blackberry. Females lay 5 – 6 eggs in May and June, incubating them for about two weeks.

Diet

This bird primarily feeds on insects such as beetles and crickets but occasionally preys on small mammals, amphibians, reptiles, or even other small birds. Before consuming its next meal, the shrike regurgitates indigestible parts of its previous prey as pellets. Its unusual German name, Neuntöter (literally "nine-killer"), reflects its habit of impaling its prey on thorns to tear it apart more easily. This also helps the bird store food for times of scarcity.

Conservation

Structurally diverse habitats rich in hedgerows, shrubs, and especially thorny bushes are essential for the survival of the red-backed shrike. However, agricultural intensification has led to the loss of many of these vital habitats. Additionally, the decline in insect populations, the bird's primary food source, poses a significant threat. The LIFE Trockenrasen project supports the conservation of dry grassland habitats, ensuring the survival of this remarkable bird species.
