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.
