Lanius excubitor, also known as the great grey shrike, is a bird of prey found in northern and central Europe, Asia, and North America. This bird is characterized by its distinctive grey plumage, hooked beak, and strong talons, which it uses to hunt small rodents, insects, and other birds. Synonyms for this bird's name include butcher bird, gray shrike, and northern shrike. The name "butcher bird" comes from the fact that these birds impale their prey on thorns or sharp twigs. Gray shrike and northern shrike are descriptive names based on this bird's coloring and geographical distribution. Regardless of its name, the lanius excubitor is a remarkable predator built for survival in harsh environments.
