Pied butcherbird, Cracticus nigrogularis

The pied butcherbird (Cracticus nigrogularis) is a songbird native to Australia. Described by John Gould in 1837, it is a black and white bird 28 to 32 cm long with a long hooked bill. The head and throat are black, making a distinctive hood, while the mantle, as are much of the tail and wings.

The neck, underparts and outer wing feathers are white. The juvenile and immature birds are predominantly brown and white. As they mature their brown feathers are replaced by black feathers. Two subspecies are recognized.

Within its range, the pied butcherbird is generally sedentary. Common in woodlands and in urban environments, it is carnivorous, eating small vertebrates and insects. A tame and inquisitive bird, the pied butcherbird has been known to accept food from humans. It nests in trees, constructing a cup-shaped structure out of sticks and laying two to five eggs.

The pied butcherbird engages in cooperative breeding, with a mated pair sometimes assisted by several helper birds. The troop is territorial, defending the nesting site from intruders. The International Union for Conservation of Nature (IUCN) has assessed the pied butcherbird as being of least concern on account of its large range and apparently stable population.

Distribution and habitat
The pied butcherbird is found across much of Australia, except the far south and Tasmania. It is only rarely recorded in the Sydney Basin and absent from the Illawarra, Southern Tablelands and south coast of New South Wales. In Victoria it is found along the Murray Valley and west of Chiltern.

In South Australia it is not found in the northeast of the state nor on the Adelaide plain. It is found across Western Australia, though is absent from the Great Sandy Desert. It is generally sedentary across most of its range, with minimal seasonal movements.

It is a bird of open sclerophyll forests, eucalypt and acacia woodlands and scrublands, with sparse or no understory, or low cover with shrubs such as Triodia, Lomandra or Hibbertia. It is less common in mallee scrub.

In arid areas and northern Australia, it is more restricted to woodland alongside rivers and billabongs. It has become more common in southwest Western Australia with land clearing, though has become rare around Darwin on account of urban development.

Conservation status
The pied butcherbird is listed as being a species of least concern by the IUCN, on account of its large range and stable population, with no evidence of any significant decline.[1]

Taxonomy
The pied butcherbird was first described by the ornithologist John Gould in 1837 as Vanga nigrogularis. The type specimen was collected near Sydney. The species name is from the Latin words niger (black), and gula (throat). Gould described Cracticus picatus in 1848 from northern Australia, calling it "A miniature representative of, and nearly allied to, but distinct from, Cracticus nigrogularis."

The word picatus is Latin for "daubed with pitch", hence "black patches.[6] This was reclassified as a subspecies of C. nigrogularis. Gregory Mathews described subspecies inkermani from Queensland and subspecies mellori from Victoria and South Australia in 1912, on the basis of smaller and larger size than the nominate subspecies respectively.

Both are now regarded as inseparable from the nominate subspecies. Mathews described subspecies kalgoorli from Kalgoorlie in 1912 on the basis of its longer bill than the nominate subspecies, but is regarded today as part of subspecies picatus.

Two subspecies are recognised today. The nominate subspecies nigrogularis is found across eastern Australia, and subspecies picatus is found in the Northern Territory, Western Australia and northern South Australia. The latter subspecies has a broader (3.7 cm wide) white collar and a more whitish rump, with specimens becoming smaller in the more northern parts of the range.

The border between the two subspecies lies in the Gulf Country and is known as the Carpentarian Barrier. Although there is a demarcation in physical characters, this is not borne out genetically, and birds from northwestern Australia have affinities with the eastern subspecies. Analysis of mitochondrial DNA sequences indicates the pied butcherbird has expanded rapidly from many refugia during the Pleistocene.

The pied butcherbird is one of six (or seven) members of the genus Cracticus known as butcherbirds. Within the genus, it is most closely related to the Tagula butcherbird (C. louisiadensis) and hooded butcherbird (C. cassicus). The three form a monophyletic group within the genus, having diverged from ancestors of the grey butcherbird around five million years ago.

The butcherbirds, Australian magpie (Gymnorhina tibicen) and currawongs (Strepera spp.) were placed in the family Cracticidae in 1914 by John Albert Leach after he had studied their musculature. American ornithologists Charles Sibley and Jon Ahlquist recognised the close relationship between woodswallows and the butcherbirds in 1985, and combined them into a Cracticini clade, which became the family Artamidae in 1994.

"Pied butcherbird" has been designated the official name by the International Ornithological Committee (IOC). Black-throated butcherbird is an alternative common name, as are Break o'day boy and organbird. Leach also called it the black-throated crow shrike, a name used by Gould for subspecies nigrogularis while calling subspecies picatus the pied crow-shrike.

‘Jackeroo’ is a colloquial name from the Musgrave Ranges in Central Australia. Gould recorded Ka-ra-a-ra as a name used by indigenous people of Darwin. The Ngarluma people of the western Pilbara knew it as gurrbaru. In the Yuwaaliyaay dialect of the Gamilaraay language of southeastern Australia, it is buubuurrbu. Names recorded from central Australia include alpirtaka and urbura in the Upper Arrernte language.

Description

Like other butcherbirds, the pied butcherbird is stockily built with short legs and a relatively large head. It ranges from 28 to 32 cm long, averaging around 31 cm, with a 51 cm wingspan and weight of around 120 g. The wings are fairly long, extending to half-way along the tail when folded.

Its plumage is almost wholly black and white, with very little difference between the sexes. It has a black head, nape and throat, giving it the appearance of a black hood, which is bounded by a white neck collar, which is around 3.2 cm wide. The black hood is slightly glossy in bright light, can fade a little with age, and is slightly duller and more brownish in the adult female.

The neck collar in the female is slightly narrower at around 2.5 cm and is a grey-white rather than white. Several stiff black bristles up to 1.5 cm long arise from the lower lores. The upper mantle and a few of the front scapulars are white, contrasting sharply with the black lower mantle and the rest of the scapulars.

The rump is pale grey, and the upper tail coverts are white. The tail is rather long, with a rounded or wedge-shaped tip. It has twelve retrices, which are black in colour. The tail tip and outer wing feathers are white.

The underparts are white. The eyes are a dark brown, the legs grey and the bill a pale bluish grey tipped with black, with a prominent hook at the end.

The juvenile pied butcherbird has dark brown instead of black plumage, lacks the pale collar and has a cream to buff lores, chin, and upper throat, becoming more brown on the lower throat and breast. Its underparts are off-white to cream. The bill is dark brown.

In its first year, it moults into its first immature plumage, which resembles that of the juvenile, but has a more extensive dark brown throat. Its bill is blue-grey with a dark brown or blackish tip.

Voice
The pied butcherbird has been considered the most accomplished songbird in Australia, its song described as a "magic flute" by one writer, richer and clearer than the Australian magpie. Song melodies vary across the continent and no single song is sung by the whole population.

There is no clear demarcation between simple calls and elaborate songs: duets, and even larger choirs, are common. The species improvises extensively in creating new and complex melodies. One of its calls has been likened to the opening bars of Beethoven's Fifth Symphony. Singing often takes place at dawn, and rarely late in the day. Pied butcherbirds sometimes sing on moonlit nights.

Three types of song have been described: the day song is the most common, sung by birds alone or in pairs as a chorus or an antiphonal duet, generally over the course of the day and while the birds are in flight. It appears to promote bonding and act as communication.

The whisper song is sung more commonly in wet or windy weather, the singer sitting in a tree warbling soft and complex harmonies for up to 45 minutes, often mimicking many other bird species as well as dogs barking, lambs bleating or even people whistling.

In the breeding season, pied butcherbirds sing the breeding song at night until dawn, when they switch to the day song. This song is longer and more complex than the day song. In response to threats, pied butcherbirds may chatter or make a harmonic alarm call composed of short, loud descending notes.

Similar species
The black hood helps distinguish the pied butcherbird from other butcherbirds, the Australian Magpie and much smaller Magpie-lark, the latter of which also has a much smaller beak. It has a higher-pitched call than the grey butcherbird and inhabits more open habitat. The juvenile pied butcherbird resembles the grey butcherbird: it has a buff upper throat and dark brown instead of black plumage.
