Great Grey Shrike

On males the upperparts are darker; the forehead is less whitish more grey; the white supercilium is narrower; the white on the primaries and secondaries, on the bases of central tail feathers and on the terminal parts of outer four pairs of tail feathers is less extensive than on homeyeri. The white on tertials is less or no presented. Uppertail coverts are usually pale-grey, sometimes off-white. The white underparts are without dark pattern.
