The black-winged myna [2] (Acridotheres melanopterus) 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. [3]

Description

The black-winged myna is a small myna, 23 centimetres (9.1 in) in length. The plumage of this species is striking, with the head, breast, back and rump being white, and the tail and parts of the wings glossy black. The tip of the tail and parts of the wings are also white. The skin around the eye is unfeathered and yellow. The bill is yellow, and slightly darker towards the base. The sexes are alike, and young birds are like the adults except that juveniles' crown and back are grey. The subspecies tricolor is similar to the nominate but has a grey back and much more black on the wings. The subspecies tertius is similar to tricolor except the grey on the back descends to the tail. [3]

Its natural habitats are tropical dry forests, tropical dry shrubland, tropical moist shrubland, and pastureland, from sea-level up to 2400 meters. Until recently it had adjusted to human-modified habitats well, moving into orchards, lawns, suburban areas and other cultivated land. [3]

Behaviour and ecology

The black-winged myna feeds on a variety of items, including fruit, nectar and insects. It feeds in small groups and in pairs, both in trees and on the ground. It roosts communally at night in groups, sometimes with other starling species like the Bali myna. It is a seasonal breeder, although the exact timing of the breeding season varies by location. Birds in west Java breed from March to May, but in east Bali the season is around June. They are apparently monogamous, nesting in a twig lined hole amongst rocks or in a tree. [3]

Status and conservation

The black-winged myna was once an abundant bird, so much so that it was considered a potential rival and threat to the threatened Bali myna. [4] The species has declined, however, for much the same reasons as the Bali myna, principally collection for the caged-bird trade. [5] The black-winged myna is one of the most popular species among collectors; in recent years the number of birds entering the trade has declined as they have become increasingly rare in the wild. It is believed that the population has declined by at least 80% over the last 10 years. The species is also potentially threatened by changes in agricultural processes, and scientists are also concerned about genetic variation being lost as escapees mix the three subspecies. [1] Escapees of this species briefly formed a breeding population in Singapore, but that population is now thought to be extinct. [3] A captive breeding program has been started at Cikananga Wildlife Rescue Center in West Java, and produced 200 chicks by 2012. Twenty-five of these birds were used to supplement the wild population, using nest boxes that local villages had produced. Several reintroductions were planned, one at Antam Pongkor Gold Mine in Gunung Halimun Salak National Park and another Rawadanau Nature Reserve in Banten Province, though the former was setback after the property was transferred to national park authorities, who immediately relaxed trapping prevention, resulting in the decline from forty individuals to eight.

<span class="mw-page-title-main">Starling</span> Family of birds

Starlings are small to medium-sized passerine birds in the family Sturnidae. The Sturnidae are named for the genus Sturnus, which in turn comes from the Latin word for starling, sturnus. The family contains 128 species which are divided into 36 genera. Many Asian species, particularly the larger ones, are called mynas, and many African species are known as glossy starlings because of their iridescent plumage. Starlings are native to Europe, Asia, and Africa, as well as northern Australia and the islands of the tropical Pacific. Several European and Asian species have been introduced to these areas, as well as North America, Hawaii, and New Zealand, where they generally compete for habitats with native birds and are considered to be invasive species. The starling species familiar to most people in Europe and North America is the common starling, and throughout much of Asia and the Pacific, the common myna is indeed common.

<span class="mw-page-title-main">Myna</span> Common name for several species of birds

The mynas are a group of birds in the starling family (Sturnidae). This is a group of passerine birds which are native to 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.

The spotless starling is a passerine bird in the starling family, Sturnidae. It is closely related to the common starling, but has a much more restricted range, confined to the Iberian Peninsula, Northwest Africa, southernmost France, and the islands of Sicily, Corsica and Sardinia. It is largely non-migratory.

<span class="mw-page-title-main">Jungle myna</span> Species of bird

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.

<span class="mw-page-title-main">Common hill myna</span> Species of bird

The common hill myna, sometimes spelled "mynah" and formerly simply known as the hill myna or myna bird, is the myna most commonly sighted in aviculture, where it is often simply referred to by the latter two names. It is a member of the starling family (Sturnidae), resident in hill regions of South Asia and Southeast Asia. The Sri Lanka hill myna, a former subspecies of G. religiosa, is now generally accepted as a separate species G. ptilogenys. The Enggano hill myna and Nias hill myna are also widely accepted as specifically distinct, and many authors favor treating the southern hill myna from the Nilgiris and elsewhere in the Western Ghats of India as a separate species.

All subspecies have the same habits of gleaning for insects and are often seen in mixed-species foraging flocks, usually foraging in small groups, high up in the forest canopy.

They are found in flocks on the plains of northern and central India, often within towns and cities. Their range appears to be extending southwards into India. The name is derived from their habit of nesting almost exclusively in the earthen banks of rivers, where they excavate burrows and breed in large colonies.
