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:

Lowland Akalat
Sheppardia cyornithopsis
A small shy akalat found in the lower levels of tall forests, often in dark shady areas near water. Note the reddish-brown back and wings, the gray face, and the bright red-orange chest contrasting with a white belly. Almost always found in lowland forest, but a few local populations are found higher up in the foothills. Within its range, most likely to be confused with Forest Robin, but note Lowland Akalat’s plain gray face and distinctive vocalizations. Song is a series of clear, melancholy whistles given with slight pauses in between, “wheeer, gowheer,” as well as faster, more resonant and metallic series of whistles.
Noisy Friarbird
Philemon corniculatus
Large gray-brown honeyeater with a completely bare black head and a distinctive "horn" on the bill. Upperparts are gray and underparts are dull white. Completely bare head is unique among the friarbirds. Typically very loud; emits a variety of harsh, loud squawks. Inhabits a wide range of habitats in eastern Australia, including (especially) open forests and gardens and parks, where it is common.
Ochre-bellied Flycatcher
Mionectes oleagineus
Rather plain, inconspicuous small flycatcher of humid tropical forest; also wanders into adjacent clearings and semiopen areas with fruiting bushes and trees. Usually found singly at lower to middle levels in shady understory and at times with mixed-species feeding flocks. Feeds mainly on fruit, plucked by short sallies. Plain olive plumage with ochre belly is distinctive. Also has habit of lifting one wing at a time and moving head slowly back and forth.
