Cacomantis variolosus | |
The Sahul brush cuckoo (Cacomantis variolosus), formerly known as the brush cuckoo, is a member of the cuckoo family. It is native to Malesia, New Guinea, the Solomon Islands and northern and eastern Australia. It is a grey-brown bird with a buff breast. Its call is a familiar sound of the Australian and Indonesian bush.
Eight subspecies are recognised: [2]
The Manus brush cuckoo (Cacomantis blandus) and the Solomons brush cuckoo (Cacomantis addendus) were formerly treated as subspecies. [2]
Most are geographically isolated, though some come into contact outside of the breeding season. For example, on Seram, members of the nominate subspecies variolosus join the local aeruginosus during the southern hemisphere winter. [3]
The convention of uniting the subspecies under C. variolosus dates back at least to Peters' checklist, [4] but there is uncertainty about whether they all belong there or not. For example, some ornithologists treat sepulcralis as a species in its own right (the Rusty-breasted cuckoo). [5] [6] Likewise, aeruginosus is elevated by some to species level (the Moluccan cuckoo), but is placed by others under C. sepulcralis. Some ornithologists treat infaustus as part of C. variolosus and others as part of C. sepulcralis. The uncertainty arises because differences between the subspecies in characteristics such as plumage colour can be minimal, while differences in vocalisations are often significant. [3] [5]
The Sahul brush cuckoo is about 22–26 cm (8.7–10.2 in) long. The plumage of adult males and females is similar. The head is pale grey, the breast is buff, the back is grey-brown, and the underside of the tail is brown with white tips and bars. [7] The eye has a narrow, pale ring around it, and the feet are olive-pink. Juvenile plumage is heavily barred dark brown. The wings are sharply pointed and backswept in flight. Underwings are grey-brown with pale buff underwing coverts and a white or pale buff bar. [7] The Sahul brush cuckoo has a similar appearance to the pallid cuckoo, and especially the fan-tailed and chestnut-breasted cuckoo. [7]
The Sahul brush cuckoo is found in northern and eastern Australia, the Solomon Islands, New Guinea, Malaysia, and other islands to the north of Australia. [7] It is resident in parts of its range, such as in Thailand, peninsular Malaysia, Cambodia and southern Vietnam, the Philippines, the Greater Sunda Islands, Lesser Sunda Islands, the Maluku Islands and Timor. It may migrate locally in New Guinea and northern Melanesia. In Australia, it is migratory in the southern part of its range. [8]
In Australia, it is known to inhabit a range of environments including rainforests, rainforest edges, mangrove forests, secondary forests, and plantations. [9]
The Sahul brush cuckoo is a brood parasite. Its eggs are polymorphic, [10] meaning females lay specific egg types for specific hosts. In Australia, females lay three types of egg depending on their major host in the relevant region of their distribution. [11]
Across its Australian range the Sahul brush cuckoo exploits at least 58 other avian species, [9] [12] though only a small number of species have been observed raising chicks through fledging. The species observed to raise chicks through fledging vary by subspecies of the Sahul brush cuckoo. For C. v. dumetorum they include the purple-crowned fairywren, brown-backed honeyeater, bar-breasted honeyeater and for C. v. variolosus they include the rose robin, Norfolk robin, leaden flycatcher, restless flycatcher, satin flycatcher, rufous fantail and grey fantail. [12] [11]
In Indonesia, observed hosts of the local subspecies of Sahul brush cuckoo include the grey-headed canary-flycatcher, [13] Javan blue flycatcher, [13] [14] snowy-browed flycatcher, [13] Sunda forktail, [13] long-tailed shrike, [13] [15] striated grassbird, [13] [15] sooty-headed bulbul, [13] yellow-vented bulbul, [13] Malaysian pied fantail, [13] [14] [15] rufous-tailed fantail, [13] pied bush chat, [13] Buru white-eye [16] and Sangkar white-eye. [16]
The cuckoo, common cuckoo, European cuckoo or Eurasian cuckoo is a member of the cuckoo order of birds, Cuculiformes, which includes the roadrunners, the anis and the coucals.
The willie wagtail, scientific name Rhipidura leucophrys, is a passerine bird native to Australia, New Guinea, the Solomon Islands, the Bismarck Archipelago, and Eastern Indonesia. It is a common and familiar bird throughout much of its range, living in most habitats apart from thick forest. Measuring 19–21.5 cm in length, the willie wagtail is contrastingly coloured with almost entirely black upperparts and white underparts; the male and female have similar plumage.
Cuculus saturatus, better well known as the Himalayan cuckoo or Oriental cuckoo, is a brooding parasitic bird that is part of the Cuculidae family. The species breeds from the Himalayas eastward to southern China and Taiwan. It migrates to southeast Asia and the Greater Sunda Islands for the winter.
The Australian rufous fantail is a small passerine bird, most commonly known also as the black-breasted rufous-fantail or rufous-fronted fantail, which can be found in Australia.
The red-capped robin is a small passerine bird native to Australia. Found in drier regions across much of the continent, it inhabits scrub and open woodland. Like many brightly coloured robins of the family Petroicidae, it is sexually dimorphic. Measuring 10.5–12.5 cm (4.1–4.9 in) in length, the robin has a small, thin, black bill, and dark brown eyes and legs. The male has a distinctive red cap and red breast, black upperparts, and a black tail with white tips. The underparts and shoulders are white. The female is an undistinguished grey-brown. This species uses a variety of songs, and males generally sing to advertise territories and attract females. Birds are encountered in pairs or small groups, but the social behaviour has been little studied.
The chestnut-breasted cuckoo is a species of cuckoo in the family Cuculidae. It is found in Australia, Indonesia, and Papua New Guinea. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical mangrove forests.
Cacomantis is a genus of cuckoos in the family Cuculidae. The name is from the Ancient Greek κακομαντις (kakomantis) meaning "prophet of evil". Most species have a round nostril and are mainly in brown and gray colours. The tails are graduated and barred. The bars are transverse in sonneratii and oblique in all others.
The fan-tailed cuckoo is a species of cuckoo in the family Cuculidae. It is found in Australia, Fiji, New Caledonia, New Zealand, New Guinea, Solomon Islands, and Vanuatu.
The Sunda brush cuckoo is a species of cuckoo in the family Cuculidae. It is found in Indonesia, Malaysia, the Philippines, Singapore, and Thailand. Its natural habitat is subtropical or tropical moist lowland forests. It was formerly treated as conspecific with the Sulawesi brush cuckoo with the English name "rusty-breasted cuckoo".
The pallid cuckoo is a species of cuckoo in the family Cuculidae. It is the only species placed in the genus Heteroscenes. It is found in Australia, with some migration to the islands of Timor and Papua New Guinea. It is between 28 and 33 cm in size, with distinctive markings such as a dark bill, a dark eye with a gold eye-ring and olive grey feet which differentiate it from other cuckoos. The pallid cuckoo is similar in appearance to the oriental cuckoo, with barred immature pallid cuckoos being often mistaken for oriental cuckoos.
The pavonine cuckoo is a Neotropical cuckoo with a long graduated tail and a short crest. It is one of three species of Neotropical cuckoo which are known to be brood parasites.
The mangrove gerygone is a species of bird in the Australian warbler family Acanthizidae. The species is also known as the mangrove warbler. The species is thought to form a superspecies with the closely related fan-tailed gerygone of Melanesia and the Australian western gerygone. There are three subspecies of mangrove gerygone, G. l. pallida, found in southern New Guinea, the nominate race G. l. levigaster, which is found from coastal Western Australia to coastal north Queensland and is known as Buff-breasted Flyeater, and G. l. cantator, which is found from coastal Queensland to New South Wales. The species is uncommon in New Guinea and has suffered some declines due to mangrove clearances but is not considered threatened by the IUCN.
The leaden flycatcher is a species of passerine bird in the family Monarchidae. Around 15 cm (6 in) in length, the male is lustrous azure with white underparts, while the female possesses leaden head, mantle and back and rufous throat and breast. It is found in eastern and northern Australia, Indonesia, and Papua New Guinea. Its natural habitat is subtropical or tropical mangrove forests in the northern parts of its range, in the south and inland it is eucalypt woodland.
The Sunda cuckoo or Sunda lesser cuckoo is a South-east Asian bird belonging to the genus Cuculus in the cuckoo family, Cuculidae. It was formerly classified with the Himalayan cuckoo and Oriental cuckoo in a single species, C. saturatus, but is now often regarded as a separate species based on differences in voice, size and plumage.
The Sulawesi brush cuckoo is a species of cuckoo in the family Cuculidae. It is found on Sulawesi and some surrounding islands: Banggai Islands, Sula Islands, Butung Island and the Tukangbesi Islands. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is threatened by habitat loss.
The Manus brush cuckoo is a species of cuckoo in the family Cuculidae. It is found on the Ninigo and Admiralty Islands which lie to the north of New Guinea. The species was formerly considered as conspecific with the Sahul brush cuckoo.
The Solomons brush cuckoo is a species of cuckoo in the family Cuculidae. It is found on the Solomon Islands apart from Rennell Island. The species was formerly considered as conspecific with the Sahul brush cuckoo.
