   Piumaggio

   Colorazione e disegno generale del piumaggio.

   Males have a grey crown and nape, a prominent black mask extending from the beak through the eye, a rufous-chestnut back, and pinkish-white underparts. The wings are dark brown with a small white patch at the primary bases (often concealed). The tail is black with white outer tail feathers. Females are duller, with a brownish-grey crown, a less distinct brownish mask, a rufous-brown back, and buffy-white underparts with fine crescent-shaped barring on the flanks and breast. Juveniles resemble females but are more heavily barred and mottled overall, with a scaly appearance on the back.

   Dimorfismo sessuale

   Differenze tra maschi e femmine.

   Pronounced. Males are much more brightly colored with a grey head, black mask, and rufous back. Females are duller, browner overall, with a less distinct mask and barred underparts.

Segni di campo chiave

• Male Plumage. Look for the distinctive combination of a grey head, black mask, and rufous-chestnut back. Pinkish-white underparts are also characteristic.
• Female Plumage. Identify by the brownish-grey head, less distinct brownish mask, rufous-brown back, and buffy-white underparts with fine crescent-shaped barring.
• Juvenile Plumage. Note the heavily barred and mottled brown appearance, especially the scaly pattern on the back and underparts.
• Behavior. Observe its 'butcher bird' behavior: perching prominently, scanning for prey, and the characteristic impaling of prey on thorns or barbed wire.
• Beak Shape. The strong, hooked beak with a distinct tomial tooth is a key shrike feature.
• Habitat. Search in open, scrubby habitats with scattered bushes and trees, often near agricultural fields or meadows.
