The Javan green magpie (Cissa thalassina) is a passerine bird in the crow family, Corvidae. This critically endangered species is endemic to montane forests on the Indonesian island of Java. [1] [2] It formerly included the Bornean green magpie as a subspecies, in which case the "combined" species was known as the short-tailed magpie. [2]
Once common, the species has declined drastically as a result of habitat loss and illegal capture for the wild animal trade. [3] The size of the remaining wild population is unknown, but perhaps only around 50 individuals, [3] while others speculate that the lack of recent sightings might mean that it already is extinct in the wild. [4]
In an attempt at saving the species, a captive breeding program based on confiscated individuals has been initiated by the Cikananga Wildlife Center in Java (since 2011) and a few European EAZA zoos (since 2015). [3] [5] It has successfully bred at both the Javan and European facilities, [4] [5] and as of 2018 this captive population had reached about 50 individuals. [6]
Javan green magpies are primarily a vivid green, with a black "mask" marking around their eyes, russet wings, and white tertiary feathers. They have bright red beaks and eyerings; their legs are equally bright, ranging from red to orange. Their eyes are dark brown and they have a relatively short tail.
The bright green plumage is the result of a combination of structural coloration, and the yellow pigment lutein, which they gain from their insect diet. [3] They also feed on small lizards and frogs. [4]
In captivity, adults turn bluish (the structural colour of their feathers) if their diet is inadequate in lutein. [3]
Javan green magpies lay cream coloured speckled eggs [7] and are altricial, hatching with no feathers, completely dependant on their parents. A fledgeling's initial plumage is bluish, with the dark face and wing markings. They have beige-brown beaks and eyerings with light orange legs. After their first moult they become green. [5]
The common green magpie is a member of the crow family, roughly about the size of the Eurasian jay or slightly smaller. In the wild specimens are usually a bright green colour, slightly lighter on the underside and has a thick black stripe from the bill to the nape. Compared to the other members of its genus, the white-tipped tail is quite long. This all contrasts vividly with the red fleshy eye rims, bill and legs. The wings are reddish maroon.
Cissa is a genus of relatively short-tailed magpies, sometimes known as hunting cissas, that reside in the forests of tropical and subtropical southeast Asia and adjacent regions. The four species are quite similar with bright red bills, primarily green plumage, black mask, and rufous wings.
The orange-bellied parrot is a small parrot endemic to southern Australia, and one of only three species of parrot that migrate. It was described by John Latham in 1790. A small parrot around 20 cm (8 in) long, it exhibits sexual dimorphism. The adult male is distinguished by its bright grass-green upper parts, yellow underparts and orange belly patch. The adult female and juvenile are duller green in colour. All birds have a prominent two-toned blue frontal band and blue outer wing feathers.
The Moluccan eclectus 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.
The Indochinese green magpie or yellow-breasted magpie, is a passerine bird of the crow family, Corvidae. It is native to mainland southeast Asia (Indochina) and adjacent China.
The colourful princess parrot is an Australian bird of the parrot family. Its name was given in honour of Princess Alexandra of Denmark, who in 1863 married the Prince of Wales Edward VII and eventually became Queen of the United Kingdom. Other names for the species include: Queen Alexandra parrot, Alexandra's parakeet, Princess of Wales parakeet, rose-throated parakeet, and spinifex parrot. Their plumage is mostly green with a pink throat, bluish crown and rump, and bright green shoulders.
The milky stork is a stork species found predominantly in coastal mangroves around parts of Southeast Asia. It is native to parts of Cambodia, Vietnam, Malaysia and Indonesia. They were once part of the genus Ibis, but is currently included in the genus Mycteria, due to similarities with other storks in that genus.
Fischer's lovebird is a small parrot species of the genus Agapornis. They were originally discovered in the late 19th century. They are named after German explorer Gustav Fischer.
The yellow-headed amazon, also known as the yellow-headed parrot and double yellow-headed amazon, is an endangered amazon parrot of Mexico and northern Central America. Measuring 38–43 centimetres (15–17 in) in length, it is a stocky short-tailed green parrot with a yellow head. It prefers to live in mangrove forests or forests near rivers or other bodies of water. It is sometimes considered a subspecies of the yellow-crowned amazon. It is a popular pet and an excellent talker. Poaching for the international pet trade has driven the species to near-extinction in the wild; around half of all wild-caught birds are thought to die in the process.
The red-fronted parrot, also known as Jardine's parrot, is a medium-sized mainly green parrot distributed across wide areas of Africa. It has three subspecies. The extent and shade of the red or orange plumage on its head, thighs, and bend of wings vary depending on the subspecies.
The white-necked rockfowl is a medium-sized bird in the family Picathartidae, with a long neck and tail. Also known as the white-necked picathartes, this passerine is mainly found in rocky forested areas at higher altitudes in West Africa from Guinea to Ghana. Its distribution is patchy, with populations often being isolated from each other. The rockfowl typically chooses to live near streams and inselbergs. It has no recognized subspecies, though some believe that it forms a superspecies with the grey-necked rockfowl. The white-necked rockfowl has greyish-black upperparts and white underparts. Its unusually long, dark brown tail is used for balance, and its thighs are muscular. The head is nearly featherless, with the exposed skin being bright yellow except for two large, circular black patches located just behind the eyes. Though the bird is usually silent, some calls are known.
The blue-streaked lory is also known as the blue-necked lory. It is a medium-sized parrot (31 cm), which is found on the Tanimbar Islands and Babar in the southern Moluccas.
The red-and-blue lory is a small, strikingly-colored parrot endemic to Indonesia. The species inhabits a single island, Karakelong, in the Indonesian archipelago, although it was formerly found on the Sangihe Islands and other parts of the Talaud Islands.
The red-browed amazon is a species of parrot in the family Psittacidae. It is endemic to Atlantic Forest in eastern Brazil. It has been considered a subspecies of the blue-cheeked amazon, but today all major authorities consider them separate species. It is threatened both by habitat loss and by being captured for the trade in wild parrots.
The Javan kingfisher, sometimes called the blue-bellied kingfisher or Java kingfisher, is a medium-sized kingfisher endemic to the Indonesian islands of Java and Bali.
The Javan warty pig, also called Javan wild pig, is an even-toed ungulate in the family Suidae. It is endemic to the Indonesian islands Java and Bawean, and is considered extinct on Madura. It is listed as Endangered on the IUCN Red List since 1996.
The sun parakeet, also known in aviculture as the sun conure, is a medium-sized, vibrantly colored parrot native to northeastern South America. The adult male and female are similar in appearance, with black beaks, predominantly golden-yellow plumage, orange-flushed underparts and face, and green and blue-tipped wings and tails. Sun parakeets are very social birds, typically living in flocks. They form monogamous pairs for reproduction, and nest in palm cavities in the tropics. Sun parakeets mainly feed on fruits, flowers, berries, blossoms, seeds, nuts, and insects. Conures are commonly bred and kept in aviculture and may live up to 30 years. This species is currently threatened by loss of habitat and trapping for plumage or the pet trade. Sun parakeets are now listed as endangered by the IUCN.
The lilacine amazon or Ecuadorian red-lored amazon is an amazon parrot native to Ecuador in South America. According to the IOC World Bird List, it is still considered to be a subspecies of the red-lored amazon, although Birdlife International considers it to be a separate species, as Amazona lilacina - as does the International Union for Conservation of Nature for the purposes of the IUCN Red List, rating the lilacine amazon as critically endangered.
The short-tailed magpies are two species of magpies that used to be considered conspecific:
The Bornean green magpie is a passerine bird in the crow family, Corvidae. It is endemic to montane forests on the southeast Asian island of Borneo. It was formerly included as a subspecies of the Javan green magpie, but under the common name Short-tailed Green Magpie. Uniquely among the green magpies, the Bornean green magpie has whitish eyes.
