Eclectus roratus (Müller, 1776) | |
The Moluccan eclectus (Eclectus roratus) is a parrot native to the Maluku Islands (Moluccas). It is unusual in the parrot family for its extreme sexual dimorphism of the colours of the plumage; the male having a mostly bright emerald green plumage and the female a mostly bright red and purple/blue plumage. Joseph Forshaw, in his book Parrots of the World, noted that the first European ornithologists to see eclectus parrots thought they were of two distinct species. Large populations of this parrot remain, and they are sometimes considered pests for eating fruit off trees. Some populations restricted to relatively small islands are comparably rare. Their bright feathers are also used by native tribespeople in New Guinea as decorations.
Ornithologists usually classify the Moluccan eclectus as a member of tribe Psittaculini in the family Psittacidae of order Psittaciformes. However, some recent thoughts indicate a great deal of commonality between the eclectus parrots and the Lorini tribe.[ verification needed ][ citation needed ]
Sir D'Arcy Wentworth Thompson noted similarities in the skull were noted between the eclectus parrots and members of the genus Geoffroyus , specifically in the auditory meatus and the prefrontal reaching but not joining the squamosal bones. The skull of members the genus Tanygnathus is also generally similar. [2]
Three subspecies of Moluccan eclectus are known, although the species as a whole needs reviewing. Access to some regions where the species occurs is difficult due to geographical or political reasons, hence field observations have been limited. Furthermore, many skins collected in the early part of the 19th century have deteriorated in some museums. [3] However, most eclectus skins in US museums are in good condition. In captivity in the U.S., some of the most common subspecies are Vosmaer's, and the New Guinea red-sided.
The Moluccan eclectus is unusual in the parrot family for its marked visible light sexual dimorphism in the colours of the plumage. A stocky short-tailed parrot, it measures around 35 cm (14 in) in length. The male is mostly bright green with a yellow-tinge on the head. It has blue primaries, and red flanks and underwing coverts. Its tail is edged with a narrow band of creamy yellow and is dark grey edged with creamy yellow underneath, and the tail feathers are green centrally and bluer as they get towards the edges. The grand Eclectus female is mostly bright red with a darker hue on the back and wings. The mantle and underwing coverts darken to a more purple in colour, and the wing is edged with a mauve-blue. The tail is edged with yellowish-orange above and is more orange tipped with yellow underneath. The upper mandible of the adult male is orange at the base fading to a yellow towards the tip, and the lower mandible is black. The beak of the adult female is all black. Adults have yellow to orange irises and juveniles have dark brown to black irises. The upper mandible of both male and female juveniles are brown at the base fading to yellow towards the biting edges and the tip. [4] The abdomen and nape of the females are blue in most subspecies, purple abdomen and nape in the subspecies (roratus) and lavender abdomen and nape in the (vosmaeri). Females of riedeli and vosmaeri also have yellow undertail coverts. The female vosmaeri displays the brightest red of all the subspecies, both on the head and body. They don't tend to talk in clear voices until they are 1 year old.
A blue colour mutation has appeared in avicultural eclectus populations as a result of a recessive gene. The cock bird is light blue, while the hen is a combination of dark blue, white and grey. [8]
The diet of the Moluccan eclectus in the wild consists of mainly fruits, wild figs, unripe nuts, flower and leaf buds, and some seeds. In captivity, they should eat a lower sugar diet for their health as they are not flying the same mileage as a wild bird, even though they crave most fruits including mangos, figs, guavas, bananas, melons, stone fruits, grapes, citrus fruits, pears, apples, pomegranate, and papaya. The eclectus has an unusually long digestive tract, [9] so tolerates a high-fiber diet. In captivity, the Moluccan eclectus benefits from specially formulated pellets or bird biscuit diet, backed up with daily serves of 2 to 3 fruits, and 5 vegetables (& leafy greens such as endive and dandelion), and a small amount of seeds and nuts such as almonds and walnuts to be used as treats. Keeping seed and nuts to be fed by hand as treats restricts over intake of oils, which can happen if these are just put into feed bowls.
In its natural habitat, the Moluccan eclectus nests within hollows in large, emergent rainforest trees. Suitable hollows are at a premium and the hen vigorously defends her chosen nesting site from other females (perhaps even fighting to the death), remaining resident at 'her tree' for up to 11 months of the year, rarely straying from the entrance to her hollow and relying on multiple males to feed her via regurgitation. Males may travel up to 20 km to forage and up to five males will regularly provide food for each female, each competing with the others for her affections and the right to father her young. Unlike other parrot species, eclectus parrots are polygynandrous—females may mate with multiple male suitors and males may travel from nesting site to nesting site to mate with multiple females. This unique breeding strategy may explain the pronounced sexual dimorphism of the eclectus, as the female must remain conspicuous at the entry to the nest hole (to advertise her presence at her hollow to males and rival females), but well hidden when in the depths of the nest, because the red color hides her well in the darkness. The male is primarily a brilliant green color, which offers camouflage amongst the trees whilst foraging. However, the plumage of both sexes appears spectacular when viewed in the ultraviolet spectrum, an ability which predators such as hawks and owls lack. [10]
Two white 40.0 mm × 31.0 mm (1.57 in × 1.22 in) eggs are laid, which are incubated for 28–30 days. Young fledge at about 11 weeks. [11] Although eclectus parrots may reach sexual maturity earlier or later, they usually reach it between 2–3 years. [12]
Moluccan eclectus hens have a strong maternal instinct, which is displayed in captivity, where they constantly seek possible nesting places, climbing into cupboards, drawers, and spaces beneath furniture, and becoming very possessive and defensive of these locations. An unpaired hen may go on to lay infertile eggs with little encouragement in the spring. It is often possible to place abandoned eggs from other parrot species beneath a broody eclectus hen, which she will readily accept and then incubate to the point of hatching, even rearing the hatched chick up to the point it is removed from the nest.
Adult females with poor nest hollows often commit infanticide on the male, if they produce both a male and a female chick. Inadequate nest hollows have a habit of flooding in heavy rain, drowning the chicks or eggs inside. [13] This reported infanticide in wild pairs may be the result of other causes, since this behavior where the hen selectively kills male chicks is not observed in captive birds.
Moluccan eclectus parrots are one of the more popular birds kept in captivity, as either parent or hand reared. Unlike many other species of parrot they are relatively easy to breed yet difficult to hand feed. [14]
Moluccan eclectus are generally calm birds in captivity, displaying a pensive affect when faced with novel items or situations, [15] which may give rise to the mistaken impression that the species is 'dull-witted'. [16] The eclectus may also exhibit more neophobia than other species of companion bird. [15] Eclectus parrots are prone to feather destruction (picking, pulling, cutting, and / or barbing) in captivity. [17]
The subspecies E. r. vosmaeri is the most commonly kept in aviculture over all. [6]
The average lifespan of the Moluccan eclectus in captivity is unknown, since these birds were not kept in captivity in great numbers until the 1980s. [18] Some sources consider the lifespan to be 30 years. [19] The maximum reliably recorded longevity for this species is 28.5 years, but a lifespan of 40.8 years has also been reported. [20]
Moluccan eclectus in captivity are prone to "toe tapping" – characterized by involuntary extension and contractions of the muscles of the feet that cause the bird to constantly tap its toenails against a perch. It is believed to be related to bird's diet and may be a result of providing the eclectus with food fortified with vitamins, processed food intended for humans (particularly containing man-made vitamins or preservatives) or food containing spirulina. [21]
A cockatoo is any of the 21 species of parrots belonging to the family Cacatuidae, the only family in the superfamily Cacatuoidea. Along with the Psittacoidea and the Strigopoidea, they make up the order Psittaciformes. The family has a mainly Australasian distribution, ranging from the Philippines and the eastern Indonesian islands of Wallacea to New Guinea, the Solomon Islands and Australia.
The red-rumped parrot, also known as the red-backed parrot or grass parrot, is a medium-sized broad-tailed parrot endemic to open woodland in south-eastern Australia, particularly in the Murray-Darling Basin. It is a highly sexually dimorphic species, with the adult female mainly being a greyish olive-green with lighter underparts and the adult male predominantly being a brightly coloured green and gold with various shades of blue on the wings. Only the adult male possesses the red rump that gives the species its common name.
The yellow-tailed black cockatoo is a large cockatoo native to the south-east of Australia measuring 55–65 cm (22–26 in) in length. It has a short crest on the top of its head. Its plumage is mostly brownish black and it has prominent yellow cheek patches and a yellow tail band. The body feathers are edged with yellow giving a scalloped appearance. The adult male has a black beak and pinkish-red eye-rings, and the female has a bone-coloured beak and grey eye-rings. In flight, yellow-tailed black cockatoos flap deeply and slowly, with a peculiar heavy fluid motion. Their loud, wailing calls carry for long distances. The yellow-tailed black cockatoo is found in temperate forests and forested areas across south and central eastern Queensland to southeastern South Australia, including a very small population persisting in the Eyre Peninsula. Two subspecies are recognised, although Tasmanian and southern mainland populations of the southern subspecies xanthanotus may be distinct enough from each other to bring the total to three. Birds of subspecies funereus have longer wings and tails and darker plumage overall, while those of xanthanotus have more prominent scalloping. The subspecies whiteae is found south of Victoria to the East of South Australia and is smaller in size.
The eastern bluebonnet, also known as the greater bluebonnet, is an Australian parrot, one of two species in the genus Northiella. It was originally included in the genus Psephotus but due to distinctive physical and behavioural differences was reclassified into its own genus in 1994 by ornithologists and taxonomists Christidis and Boles. The bluebonnet is a medium-sized inland parrot commonly found in the interior of southeastern and central-southern Australia. It is adapted to life in semi-arid regions but can also flourish in regions of medium rainfall towards the eastern and southern extremities of its range.
Eclectus is a genus of parrot, the Psittaciformes, which consists of four known extant species known as eclectus parrots and the extinct Eclectus infectus, the oceanic eclectus parrot. The extant eclectus parrots are medium-sized parrots native to regions of Oceania, particularly New Guinea and Australia. Males are mostly bright green, females are predominantly bright red. The male and female eclectus were once thought to be different species. The conservation status of the remaining species is least concern. Eclectus parrots do well in captivity, and are a very popular pet across the world.
The red-tailed black cockatoo also known as Banksian- or Banks' black cockatoo, is a large black cockatoo native to Australia. Adult males have a characteristic pair of bright red panels on the tail that gives the species its name. It is more common in the drier parts of the continent. Five subspecies are recognised, differing chiefly in beak size. Although the more northerly subspecies are widespread, the two southern subspecies, the forest red-tailed black cockatoo and the south-eastern red-tailed black cockatoo are under threat.
Rosellas are in a genus that consists of six species and nineteen subspecies. These colourful parrots from Australia are in the genus Platycercus. Platycercus means "broad-tailed" or "flat-tailed", reflecting a feature common to the rosellas and other members of the broad-tailed parrot tribe. Their diet is mainly seeds and fruit.
The scarlet-chested parrot, known alternately as scarlet-breasted parrot, orange-throated parrot or splendid parrot, is a parrot endemic to central South Australia and inland southern Western Australia. The species is sexually dimorphic; the male has a bright blue face and scarlet chest and yellow underparts, amid overall green plumage, while the female is similar but lacks the red chest. These nomadic parakeets move readily from the Great Victoria Desert region into neighbouring areas. These interruptions are triggered by a search for more favourable conditions. They can survive quite well without access to drinking water, however, as succulent plants help meet much of their fluid requirement. They feed mainly on grass seeds and are most commonly sighted in spinifex.
The mulga parrot is endemic to arid scrublands and lightly timbered grasslands in the interior of southern Australia. The male mulga parrot is multicolored, from which the older common name of many-coloured parrot is derived.
The superb parrot, also known as Barraband's parrot, Barraband's parakeet, or green leek parrot, is a parrot native to south-eastern Australia. It is a dimorphic species and one of three species in the genus Polytelis.
The pale-headed rosella, is a broad-tailed parrot of the genus Platycercus native to northeastern Australia. It is a moderate-size parrot with a pale yellow head, predominantly white cheeks, scalloped black and gold back and pale blue underparts. Two subspecies are recognised, although some authorities consider it to be conspecific with the eastern rosella of southeastern Australia.
The Moluccan king parrot is a parrot endemic to Peleng Island, Maluku, and West Papua in Indonesia. It is sometimes referred to as the Ambon king parrot or Amboina king parrot, but this is potentially misleading, as it is found on numerous other islands than Ambon. The male and female are similar in appearance, with a predominantly red head and underparts, green wings, and blue back and tail. Six subspecies are recognised, but only a few of these are regular in aviculture. In the wild, it inhabits rainforests and feeds on fruits, berries, seeds and buds.
The rock parrot is a species of grass parrot native to Australia. Described by John Gould in 1841, it is a small parrot 22–24 cm long and weighing 50–60 g with predominantly olive-brown upperparts and more yellowish underparts. Its head is olive with light blue forecheeks and lores, and a dark blue frontal band line across the crown with lighter blue above and below. The sexes are similar in appearance, although the female tends to have a duller frontal band and less blue on the face. The female's call also tends to be far louder and more shrill than the male's. Two subspecies are currently recognised.
Alisterus is a genus of medium-sized Australasian parrots, comprising the Australian king parrot, the Papuan king parrot and the Moluccan king parrot. The three species are respectively found in eastern Australia, Papua, the Moluccas and other Indonesian islands. Predominantly of red and green plumage, the long-tailed parrots are related to the genera Aprosmictus and Polytelis.
The Philippine hanging parrot, also commonly known as the colasisi from its local Tagalog name "kulasisi", is a small psittaculid parrot species endemic to the Philippines. It includes about eleven subspecies, at least one of which might represent a distinct species, although further research is needed. While it is listed as Least Concern in IUCN, some subspecies, such as L. p. chyrsonotus of Cebu and L. p. siquijorensis of Siquijor, may already be extinct. The species is threatened by habitat loss, but a bigger threat is trapping for the illegal wildlife trade; wild-caught birds are often sold as pets in streets and online selling groups.
The Sula hanging parrot is a small species of parrot in the family Psittaculidae. It is endemic to forest and nearby habitats on the Banggai and Sula Islands in Indonesia.
Arnout Vosmaer was a Dutch naturalist and collection curator.
The Papuan eclectus, red-sided eclectus, or New Guinea eclectus is a parrot species which is native to New Guinea. Larger than the Moluccan eclectus, the green plumage of the male only has a slight yellow tinge and the tail is tipped with a half-inch yellow band. The central tail feathers are green and lateral ones blue and green. It is widely distributed from Kai Islands and western islands of the West Papua province in the west, across the island of New Guinea to the Trobriands, D'Entrecasteaux Islands, Louisiade Archipelago, Bismarck Archipelago, and Solomon Islands to the east, and south to the northern Cape York Peninsula of Australia. It has also been introduced to the Goram Islands, Indonesia.
The Sumba eclectus, or Cornelia's eclectus is a parrot species which is native to Sumba. Also larger than the Moluccan eclectus, the male is a paler shade of green overall and has a bluer tail. The female has an all red plumage, except for the primaries which are a dark royal blue, and can be differentiated from the Tanimbar eclectus by the lack of yellow to her tail.
The Tanimbar eclectus, or Riedel's eclectus is a parrot species which is native to the Tanimbar Islands. It is smaller than the Moluccan eclectus. The male has a more bluish tinge to its green cheeks and neck, and its tail is edged with a broad band of yellow. The female has an all red plumage, except for royal blue primaries, yellow under-tail coverts and a broad band of yellow to edge the tail.
