The woodchat shrike (Lanius senator) belongs to the family of shrikes, the Laniidae.
The woodchat shrike species is distributed in southern Europe, Mediterranean region, west Asia, northwest Africa and sub-Saharan Africa. A vagrant shrike was recorded in Alibag, Maharashtra in India. These shrikes are polytypic species.
Appearance, physical description and identification
The woodchat shrike (Lanius senator) is a medium-sized typical shrike, measuring 18 to 20 cm in length and weighing 20 to 60 grams. These species are sexually dimorphic.The male nominate woodchat shrike has grayish brown upperparts and chestnut crown and nape. The forehead is whitish and these is a black mask across forecrown and eyes. There are broad white patches on dark wings. The rump is white and the tail is dark.

Ecosystem and habitat
These woodchat shrike species have low forest dependence. They normally occur in altitudes from 0 to 2400 meters. The artificial ecosystems and habitats of these shrike species include heavily degraded tropical and subtropical forests, agricultural lands, old orchards and rural gardens.The natural ecosystems and habitats of these shrike species include open woodlands, tropical and subtropical dry grasslands, tropical and subtropical moist lowland forests, semi-open areas with bushes and well-spaced trees, high altitude grasslands and dry shrublands.
Diet and feeding behavior
The diet of these woodchat shrike species consists mainly of large insects. Insects like grasshoppers, dragonflies, ground beetles, scarab beetles, wasps, bees and also vertebrates like small voles, mice, lizards, frogs and birds are their primary food.These shrikes occasionally feed on plant material like fruits and berries. They hunt their prey from prominent perches and impale the catch on thorns, before consuming. For this feeding habit, they are also known as "butcher birds".
Reproduction and breeding habits
The breeding season of these woodchat shrikes is during May and June in southern Europe. The laying season is during April and May in northern Africa. The breeding season in Israel is in March. The southern shrike breeders usually raise two broods.These woodchat shrike species are monogamous and highly territorial. The nesting site of the shrike is usually a lateral branch of a tree, often of oak, pine or fruit tree. They are also known to nest in low dense bush.
The woodchat shrike nest is a compact cup-like structure built with twigs and rootlets and lined with moss, lichen, wool and spiderweb. The typical clutch contains four to eight off-white eggs with brown and gray mottling.
The female woodchat shrike incubates the eggs and the chicks hatch out after 14-16 days. Both the parents feed the hatchlings. The young fledge 18-20 days later, but are dependent on parents for further three to four weeks for food.
Migration and movement patterns
These woodchat shrike species are fully migratory birds. The breeding populations occur in southern Europe, Mediterranean region and west Asia. These populations migrate to sub-Saharan Africa, north of the equator, for wintering.Woodchat shrike - Quick Facts
