The Javan myna (Acridotheres javanicus), also known as the white-vented myna, is a species of myna. It is a member of the starling family. It is native to Bali and Java. It has been introduced to other Asian countries, and as far away as Puerto Rico.
The Javan myna is sometimes included in the great myna (Acridotheres grandis) or the jungle myna (A. fuscus). The International Ornithologists' Union recommends not using the name "white-vented myna" to avoid confusion with the Pale-bellied Myna A. cinereus. [2]
The Javan myna is mainly black. The wings are brownish-black, and the primaries have white bases, displayed in flight as a striking white wing bar, along with a white tail bar. The undertail-coverts are white. There is a short crest on the forehead. Its beak, legs and feet are yellow. The eyes are lemon-yellow. The immature is browner. Its length is 21–23 cm (8.3–9.1 in). [3] Its weight is about 100 g (3.5 oz). [4]
The Javan myna is native to Bali and Java, and has been introduced to southeastern Thailand, southern Malaysia, Singapore, Sumatra, the Lesser Sundas, Taiwan, Puerto Rico, Japan and Nepal. [4] It is found in cities and cultivated areas. [3]
Javan mynas are bold and not very afraid of humans. [3] Javan mynas are kept in cages in Malaysia and Indonesia. [3]
The Javan myna is omnivorous and eats seeds, fruit, nectar, insects and human waste. [3]
Javan mynas are found in pairs and associate in larger groups. Its voice is similar to that of the common myna. It builds its nest in holes. The eggs are bluish-glaucous.
The birds scavenge in groups, minimum two but usually three or more, with all except one feeding and one usually at a vantage point keeping a look out. If the bird that is keeping watch sees anything that might pose a threat, it alarms the group members with a high pitch tweet and they all flee the area swiftly.[ citation needed ] If one of them is separated, they would tend to tweet to attract other mynas of their kind to come over.
The juvenile, or fledgling, period of a Javan myna lasts about 25 days. [5] Juveniles tend to be browner, with a very short brown frontal crest. [6] Juvenile Javan mynas will no longer be fed in the nest and will learn to beg for food from its parents. This is to teach the juvenile to feed itself. [7] When begging, juveniles stand at the same spot every now and then with its wings hanging down, fluttering lightly occasionally beside its body. All juveniles need to be taught by the adults on how to forage for food, to avoid potential predators before they can live independent lives. [8]
The eggs of a Javan myna are blue in colour and takes 13-14 days to hatch. [7]
The mynas are a group of birds in the starling family (Sturnidae). This is a group of passerine birds which are native to Iran and Southern Asia, especially Afghanistan, India, Pakistan, Bangladesh, Nepal and Sri Lanka. Several species have been introduced to areas like North America, Australia, South Africa, Fiji and New Zealand, especially the common myna, which is often regarded as an invasive species. It is often known as "Selarang" and "Teck Meng" in Malay and Chinese respectively in Singapore, due to their high population there.
The common myna or Indian myna, sometimes spelled mynah, is a bird in the family Sturnidae, native to Asia. An omnivorous open woodland bird with a strong territorial instinct, the common myna has adapted extremely well to urban environments.
The jungle myna is a myna, a member of the starling family. It is found patchily distributed across much of the mainland of the Indian Subcontinent but absent in the arid zones of India. It is easily recognized by the tuft of feathers on its forehead that form a frontal crest, a feature also found in the closely related Javan myna and the pale-bellied myna which were treated as a subspecies in the past. The eyes are pale, yellow or blue depending on the population and the base of the orange-yellow bill is dark. It has also been introduced either intentionally or accidentally into many other parts of the world including Fiji, Taiwan, the Andaman Islands, and parts of Japan. The species has also spread out on its own to some islands in the Pacific.
The brahminy starling or brahminy myna is a member of the starling family of birds. It is usually seen in pairs or small flocks in open habitats on the plains of the Indian subcontinent.
The Bali myna, also known as Rothschild's mynah, Bali starling, or Bali mynah, locally known as jalak Bali, is a medium-sized, stocky myna, almost wholly white with a long, drooping crest, and black tips on the wings and tail. The bird has blue bare skin around the eyes, greyish legs and a yellow bill. Both sexes are similar. It is critically endangered and in 2020, fewer than 50 adults were assumed to exist in the wild.
The crested myna, also known as the Chinese starling, is a species of starling in the genus Acridotheres native to southeastern China and Indochina. It is named after the tuft of feathers on its forehead that resembles a crest.
The Indian pied myna is a species of starling found in the Indian subcontinent. It is usually found in small groups mainly on the plains and low foothills. It is often seen within cities and villages although it is not as bold as the common myna. It produces a range of calls made up of liquid notes.
Acridotheres is a genus of starlings, the "typical" mynas, which are tropical members of the family Sturnidae.
The white-cheeked starling or grey starling is a passerine bird of the starling family. It is native to eastern Asia where it is a common and well-known bird in much of its range.
The pale-bellied myna is a species of starling in the family Sturnidae. It is endemic to the southwestern peninsula of Sulawesi, Indonesia. It has been introduced to Tawau, Sabah (Borneo).
The black-winged myna is a species of starling in the family Sturnidae. The species is also known as the black-winged starling or the white-breasted starling. It is endemic to Indonesia. There are three recognised subspecies: the nominate race, which occurs across much of the island of Java; tricolor, which is restricted to south east Java; and tertius, which is found on Bali and possibly Lombok. The validity of the records on Lombok has been called into question, as there are only a few records and those may represent escapees from the caged-bird trade or natural vagrants. The species has often been assigned to the starling genus Sturnus, but is now placed in Acridotheres because it is behaviourally and vocally closer to the birds in that genus.
The banded broadbill is a species of bird in the Eurylaimidae typical broadbill family found in Mainland Southeast Asia and the Greater Sunda Islands. It is sometimes split into two species, one including only the nominate subspecies, E. j. javanicus, and one including all the remaining subspecies. It inhabits a variety of forests, along with forest edge, rubber plantations and Falcataria falcata groves, mainly in lowland areas. A striking, large-bodied bird with a length of 21.5–23.0 cm (8.5–9.1 in), it is unlikely to be mistaken for another species. The broadbill is mostly purplish-red, with yellow-streaked black wings, a bright blue beak, a blackish face and greyish chin and upper breast. Females can be told apart from males by their lack of a black neckband, although these are indistinct in Bornean and Javan males. Despite its conspicuous appearance, the bird is usually hard to see due to its sluggishness and is usually only noticed when it vocalises.
