Origin, geographical range and distribution

These woodchat shrikes are distributed in southern Europe, Mediterranean region, west Asia, northwest Africa and sub-Saharan Africa.

A rare vagrant shrike was photographed at Alibaug, Maharashtra (India) and reported by Parag S. Nandgaonkar (2013), in Indian BIRDS 8 (6): 164.

The woodchat shrike nominate subspecies L. s. senator is distributed in central and southern Europe. It winters in central and western sub-Saharan Africa. The subspecies L. s. badius is distributed in islands in west Mediterranean. It winters in western Africa.

The woodchat shrike subspecies L. s. niloticus is distributed in Cyprus, south and east Turkey, Georgia, Armenia, and Azerbaijan, north Iraq, Kuwait and Iran. It winters in eastern Africa.

The woodchat shrike subspecies L. s. rutilans is distributed in Portugal, Spain, Gibraltar, Morocco, northern Algeria, northern Libya and Tunisia. The wintering populations are found in western sub-Saharan Africa.

The Important Bird and Biodiversity Areas (IBA) of these woodchat shrike species in Italy are, Coast between Marina di Camerota and Policastro Bussentino, Ausoni and Aurunci mountains, Alburni mountains and Murge.

The IBA of these woodchat shrike species in Greece are, Valtou mountains, Mount Taygetos, Mavrovouni mountain, Larissa, East Lakonia mountains and Acheloos valley.

The IBA of these woodchat shrike species in France are, Vallée du Régino, Hautes garrigues du Montpellierais, Estuaire de la Gironde : marais du Nord Médoc and Garonne : marais de Bordeaux.

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.
