Shrike Lanius collurio

Shrike Lanius collurio inhabits bushy areas, baulks and edges of forests. Shrike sits at elevated places from where it trips for prey – mostly insect but also small mammals and birds. The bird frequently places its prey on thorns to have it in stock. Therefore it is often called by people a thorn-jab, a meat-eater or a wiretap. Shrike belongs to migratory species, wintering in southern and eastern Africa. There are a few pairs of this endangered and by law protected bird species nesting in the shrubby vegetation along the Olza river.
