Red wattlebird
The red wattlebird is a passerine bird native to southern Australia. At in length, it is the second largest species of Australian honeyeater, after the yellow wattlebird. It has mainly grey-brown plumage, with red eyes, distinctive pinkish-red wattles on either side of the neck, white streaks on the chest and a large bright yellow patch on the lower belly. The sexes are similar in plumage. Juveniles have less prominent wattles and browner eyes. John White described the red wattlebird in 1790. Three subspecies are recognized.
The species is found in southeast Queensland, New South Wales, Victoria, South Australia and southwest Western Australia in open forest and woodland, and is a common visitor to urban gardens and parks. Loud and conspicuous, the red wattlebird is generally found in trees, where it gets most of its food; occasionally it forages on the ground. It is one of the largest nectarivorous birds in the world, feeding from a wide variety of flowering plants. Insects also comprise part of its diet. It is territorial and at times aggressive towards birds of other species, often defending rich sources of nectar. Breeding throughout its range, the red wattlebird builds a cup-shaped nest in a tree and raises one or two broods a year. Although it has declined in places from land-clearing, it is classified as Least Concern on the IUCN Red List.
Taxonomy
The red wattlebird was first described as the wattled bee-eater by the Irish surgeon and naturalist John White in his Journal of a Voyage to New South Wales, which was published in 1790. He wrote that it was the "size of a missel thrush, but much larger in proportion". The taxonomic descriptions in White's book are believed to have been written by the English naturalist George Shaw, who is generally credited as the author by subsequent authorities. The specific epithet, carunculata, was introduced later in the same year by John Latham. The word is derived from caruncula, Latin for 'a small piece of flesh'. Both Shaw and Latham assigned the red wattlebird to the genus Merops. The species was moved to Anthochaera in 1827 by the naturalists Nicholas Aylward Vigors and Thomas Horsfield. The generic name derives from the Ancient Greek anthos 'flower, bloom' and khairō 'enjoy'."Red wattlebird" has been designated as the official common name for the species by the International Ornithologists' Union. Other common names include gillbird, gilly warbler, barkingbird, muttonbird, butcherbird, what's o clock, and chock. Unlike many species in southwestern Australia, the red wattlebird was given names by the local indigenous people that were onomatopoeic. Names recorded include wodjalok, durdal, doongorok, and djoongong. In the Eyre Peninsula in South Australia, the local Barngarla people knew it as ngarkarko or ngarkabukko. The local people of Denial Bay in South Australia called it noggal, and the Ngarrindjeri people of the Lower Murray region in South Australia know it as rungkan.
There are three recognised subspecies, though there is a zone of intermediate birds across western Victoria and eastern South Australia, bordered by western Port Phillip Bay to the east, Mount Lofty Ranges to the west, and Little and Big Desert national parks to the north. The differences in plumage are not generally prominent enough to be noticeable in the field.
- A. c. carunculata – found in southeast Australia, namely Victoria, eastern New South Wales, and southeastern Queensland.
- A. c. clelandi – Kangaroo Island. Of a similar size to the nominate subspecies, it tends to have darker plumage, a longer bill, and shorter tarsus.
- A. c. woodwardi Mathews, 1912 – southwest and south-central Australia, west of the Mount Lofty Ranges. This subspecies is a little smaller than the nominate subspecies and has shorter wings. Its plumage is similar, though the yellow patch on the belly is more prominent.
Description
The sexes of the red wattlebird are similar in size and plumage, the length of the adult male ranging from and the adult female from. With an average weight of, the red wattlebird is one of the largest nectar-feeding birds in the world, and the second largest species of honeyeater native to Australia, eclipsed only by the yellow wattlebird. The crown, forehead and upper lores are dark brown, streaked with pale brown at the front of the crown and white at the rear of the crown. The nape is slightly paler brown, with white streaks. A whitish triangular marking covers the lower lores and anterior ear covert feathers, bordered below by a dark brown stripe from the lower mandible down to the wattle and around to behind the eye. The throat is dark brown streaked with white. The iris of the eye is orange-red to crimson. The distinctive pinkish-red wattles dangle from the lower rear corner of the ear coverts on either side of the neck, and there is a sliver of pink bare skin at the lower border of the white patch on the face. The chest and belly are streaked white, and there is a bright yellow patch towards the tail. The strong legs and feet are pink or pinkish-brown, and the downward-curving bill is black. The average dimensions of the bill are long, wide, and high at its base. The gape is grey-black, while the inside of the mouth is orange. In common with other honeyeaters, the red wattlebird has a long, specialized tongue to extract nectar from flowers. The tongue can extend well beyond the tip of the bill, and is divided at the end to form a brush-like structure with over a hundred bristles that soak up nectar by capillary action.The red wattlebird begins moulting after the breeding season, starting with the primary flight feathers in November or December, and finishing between the following March and May. The feathers of the breast, back, median and lesser covert feathers are moulted before those of the crown, remiges, and rectrices.
Immature red wattlebirds are generally less flamboyant. Juveniles have much less prominent wattles, brown irises, a pale crown, and much less yellow on the belly. They moult into first immature plumage within a few months of leaving the nest. First immature birds are more similar to adults overall, having red irises with brown rings, wattles larger but still smaller than adults, and a greyish pink gape.
The red wattlebird is hard to confuse with any other species, though in poor visibility it might be mistaken for the spiny-cheeked honeyeater, or little or western wattlebirds.
Call
Red wattlebirds are noisy animals, producing a range of raucous calls. Pairs of birds appear to duet, particularly at food sources, with the male producing a loud cackle and the female a whistling call. The male's cackle is loudest between 1 and 3 kHz frequency. A guttural-sounding call, it has been variously described as having a squawking, coughing or hiccuping sound. Males cackle when foraging by themselves, when with other birds, or when declaring their territory to other birds. The whistling call consists of up to five rapid whistles that may or may not ascend in tone, and are repeated 3–4 times. Both sexes commonly utter a single chock note that may be harsh and guttural or have 4–5 harmonics. This is thought to be a contact call. These calls all carry over long distances.Red wattlebirds utter two types of alarm calls, alternating between them while mobbing other animals. One is a harsh call over a wide frequency that is louder at lower frequencies. The other is a lower-pitched staccato call with a frequency of 1.1–2.2 kHz. They give a harsh call when trying to distract intruders from the vicinity of the nest or when picked up, often trying to flap or peck the handler.
Distribution and habitat
The red wattlebird is found in southeast Queensland, where it occurs south of Noosa and Cooloola, becoming more common south of Brisbane and Toowoomba. Further south into New South Wales it is found most places east of the Great Dividing Range and stretching west to the southern North-West Plain, Central Western Slopes and eastern Riverina, and is an occasional visitor to points along the Murray River valley. It is found across Victoria, though is uncommon in the northwest of the state. In South Australia, Devonborough Downs Station, Manunda, Wilpena Pound and Nullarbor Station mark the northern limits of its range. There are scattered records from the Nullarbor Plain, but the species is common in Western Australia west of 125 °E and south of 29 °S. The yellow wattlebird replaces it in Tasmania. The red wattlebird has become more common in some localities, such as the Sunraysia district in the 1960s, and Nambucca Heads and Lefevre Peninsula in the 1980s. Breeding numbers have increased in Sydney and Adelaide. The red wattlebird is a rare vagrant to New Zealand, with confirmed records at Matakana in 1865 and Rohutu, Taranaki, in 1885, and a third unconfirmed report from Motupiko in 1938.The red wattlebird appears to be a permanent resident in much of its range, though its movements are poorly known. It appears to be partly migratory in Western Australia and the north coast of New South Wales. In southeastern New South Wales and the Australian Capital Territory, it appears to move to lower altitudes for winter. For instance, birds vacate the Brindabella Range over the cooler months. Overall, little pattern is discernible in the species' movements, though red wattlebirds appear to move to feed on populations of flowering banksias and eucalypts, such as winter-flowering banksias in Perth over the cooler months. Large numbers arrive in time to feed on flowering native apples in Mudgee and Cobbora districts in central-western New South Wales, and on white box at Barrington in central-northern New South Wales. A mainly resident population on the Swan Coastal Plain near Perth is supplemented during winter by more arriving from inland areas. South of Perth, red wattlebirds are more locally nomadic, moving to new patches of blooming wildflowers. East of Perth in areas around Kellerberin, Kwolyin, and Nangeenan, the red wattlebird is present from late autumn to spring, breeding in August and September. Around Lake Grace, the red wattlebird is present year-round.
Open sclerophyll forest and woodland, generally dominated by eucalypts, is the most common habitat of the species. It is more common in forests with ample shrubby or grassy understory. It is less commonly encountered in shrubland, heath, or margins of wet sclerophyll forest. It is rarely found in mature pine plantations. Within urban areas, it is abundant in parks and reserves, gardens and golf courses, as well as orchards and vineyards. It occasionally ventures into subtropical, semi-arid or subalpine regions, and has been found up to above sea level. The red wattlebird is rarer in forests that have been affected by dieback.
