The head, back and upper wing feathers are gray while the tail and lower wing feathers are black. A black patch is present from the bill to past the eye. The feathers on the lower side of the bird are light gray to buff and faintly barred. The base of the lower portion of the bill is lighter in color than the rest of the bill. The immature shrike is gray-brown and has more prominent bars on the lower side than those of the adult.

The northern shrike is an uncommon winter resident in northern Illinois and a very rare winter resident in the remainder of the state. In Illinois it may be seen in open woodlands and in fence rows. This bird spends the summers in deciduous and coniferous woodlands further north than Illinois. Fall migration into Illinois begins in October and November. Spring migrants depart in March. The northern shrike eats mice and small birds. This bird is known for impaling its prey items on thorns or barbed wire.
