The Long-tailed Shrike is well distinguished from other Shrikes by the bright, contrast color and the long tail. The adult male has grey crown and nape, grey buffy tinged fore-back, brightly-buff rear-back, rump and uppertail; black forehead, lores and ear coverts. The forming black mask enframes the eyes. Above the eye over the black mask there is faint off-white supercilium. The throat, breast and abdomen are off-white with buffy tinge which is more intensive on the flanks and undertail. The wings are black-brownish. The wing coverts are almost black, primaries are dark-brown with white bases forming the little speculum almost hidden by the wing coverts; the secondaries are dark-brown with buffy edges. The central tail feathers are black-brown, next ones become paler, the outer are pale-brown buffy tinged. All tail feathers except the central pair have pale edges. The adult females are slightly dimmer; the grey on head and nape isn't clear but brownish tinged; the tail and flight feathers are not black but brown. The bill and legs are black-brown, eyes are dark-brown. Sometimes breeding young males (probably second-year) keep the partial juvenile plumage. These birds have some mottled feathers among the other grey on the crown; the secondaries and some wing coverts have pale buffy edges separated from the brown centers by the narrow strips; the dark pre-terminal bands are kept on the feathers of uppertail and breast. Juveniles in first plumage. The crown, nape and fore-back are brownish-grey with brown scaly pattern; the rear-back and uppertail are rusty with brown pattern; the flight feathers are dark-brown with rufous edges. The underparts are grayish with brown scaly pattern. The mask is pale-brown. Sizes: males – wing 90-96.8, tail 121-127; females – wing 91.6, tail 116 mm. Weight 37-42 grams.
