Lanius excubitor (Great Grey Shrike)

Scientific name: Lanius excubitor Linnaeus, 1758

Bird group: Shrikes

Field characters. 24 cm. Plumage black, grey and white. Larger than Lesser Grey Shrike. Black bill, mask, wings and tail, with white bar on wing, especially obvious in flight, and on sides of tail. Scapulars white or very light grey, showing as white band above black wings. Narrow white line above mask. Crown, neck and back grey, underparts greyish-white. Black of mask does not extend on forehead, unlike Lesser Grey Shrike. Sexes alike, female somewhat duller. Juvenile with much reduced black mask; upperparts grey-brown; underparts buff with grey-brown bars. Like other shrikes often sits on exposed perch in hunched posture, looking for prey. Wags and swings broad tail from side to side like Red-backed Shrike. Flight undulating. Agressive against intruders: even larger raptors are harassed. In winter obvious, but secretive during breeding season.

Voice. Call 'sheck' or 'truu'. Song subdued, with harsh and clear whistling notes.

Distribution. Rather scarce, but widespread.

Habitat. Breeds on moors, bogs, and pastures with scattered trees. In winter found in a wider variety of open habitats, but always with scattered bushes.

Food. Large insects and vertebrates, like small mammals, birds, and lizards. Hunts from perch like other shrikes, but also frequently hovers. Also caches prey by impaling it on thorns, barbed wire, etc.
