The grey butcherbird is a small grey, black and white bird with a weight of 90 grams (3.2 oz), a body length between 27 and 30 cm (10.6–11.8 in) and a wing span expanding 37–43 cm (14.6–16.9 in). The grey butcherbird is smaller than the Pied Butcherbird (Cracticus nigrogularis).<p>The adult grey butcherbird has a black head, top and sides; and a white chin and throat through to the lower hindneck. The upperbody is mostly dark grey with streaks of narrow white bands that extends across the uppertail-coverts at the base of the tail. The uppertail is black with narrow white tips. The wings are grey with large areas of white and the underside of the wing is also white. The tip of the beak has a slight downwards hook.<p>Both the male and female grey butcherbirds are similar in appearance, but the female is slightly smaller in size.<p>The juvenile is slightly different from the adult, as the juvenile does not have a black head, instead the head is a dark brown with fine streaks on the forehead and ear-covers and white loral spots that meet the eyes and bill, as well as having an off-white chin and throat. The upperbody is dark brown with streaks, and the uppertail-coverts are also a dark brown and have a brownish colour at the base of the uppertail. Juvenile's beaks are completely dark grey and often the hook at the tip of the beak is not obvious. The juvenile grey butcherbird is commonly mistaken for a small kingfisher.
分类信息
The grey butcherbird was first described by the English ornithologist John Latham in 1801 under the binomial name Lanius torquatus.<p>Closely related species include the silver-backed butcherbird (Cracticus argenteus) and the black-backed butcherbird (Cracticus mentalis). The silver-backed butcherbird (Cracticus argenteus) from Arnhem Land and northwestern Australia over to Port Hedland, originally described by John Gould in 1841, was later deemed to be a subspecies of the grey butcherbird. Recently, however, it has again been re-described as a separate species. The silver-backed butcherbird has two subspecies C. argenteus argenteus and C. a. colletti. The black-backed butcherbird occurs in Australia on the Cape York Peninsula and in Papua New Guinea and has two subspecies.<p>The grey butcherbird has three subspecies:

Mountain Imperial-Pigeon
Ducula badia
Large elegant pearl-gray pigeon with dark wings. Inhabits mature forests in foothills and montane areas; can be found down to sea level in western India. Forages in upper levels of forest, often in small flocks. Flies powerfully over the canopy. Song is deep and resonant: “ouh-woOO WOO.”
Magenta-throated Woodstar
Philodice bryantae
Tiny hummingbird with long tail often cocked up. Slow bumblebee-like flight. The only woodstar in its range. Male has purple throat and white collar, otherwise greenish with some orange tones on the flanks. Female more confusing but note small size and flight style; also orange flanks, dark cheek with white spot behind eye, and white patches on sides of rump. Feeds at small flowers at all levels of forest edge, also visits feeders.
Long-billed Tailorbird
Artisornis moreaui
Inconspicuous, apalis-like grayish warbler with a long tail, straight thin bill, and buff-brown forehead. Isolated population in Mozambique, sometimes considered a different species (Njesi Tailorbird), is smaller, darker, and browner on the head. Singles and pairs are very low density, shy and creep slowly through the undergrowth and canopy, especially nearby streams; sometimes joins mixed-species flocks. Song a pleasant sweet bouncing “eeh-yuh, eeh-yuh, eeh-yuh” or strident “peelik-peelik-peelik”, sometimes joined in duet with a dry buzzing “dzit”; call a high-pitched “chhet” like a squeaky dog’s toy. Similar Brown-headed Apalis is shorter-billed than Long-billed Tailorbird and has white tips to the tail.
