[14], The common myna obeys Gloger's rule in that the birds from northwestern India tend to be paler than their darker counterparts in southern India. [52], The common myna (which feeds mostly on ground-dwelling insects, tropical fruits such as grapes, plums and some berries and, in urban areas, discarded human food)[53] poses a serious threat to Australian blueberry crops, though its main threat is to native bird species. It feeds on insects, arachnids, crustaceans, reptiles, small mammals, seeds, grain and fruits and discarded waste from human habitation. An omnivorous open woodland bird with a strong territorial instinct, the common myna has adapted extremely well to urban environments. [48] The bird is also notorious for being a pest, kicking other birds out of their nests and killing their young due to the myna's strong territorial instinct. [57], In Sanskrit literature, the common myna has a number of names, most are descriptive of the appearance or behaviour of the bird. Gland, Switzerland: IUCN.. Dubois P.J. Associated with their social nature are voices that are loud and varied, though often raucous, sometimes mechanical, and rarely melodious. This is a group of passerine birds which are native to southern Asia, especially India, Pakistan and Bangladesh . Morphological variations are significant in wing and head traits of females, suggesting females as the primary dispersing sex. [17][38], The common myna is regarded as a pest in South Africa, North America, the Middle East, Australia, New Zealand and many Pacific islands. Mynas are medium-sized passerines with strong feet. [56], Common mynas can cause considerable damage to ripening fruit, particularly grapes, but also figs, apples, pears, strawberries, blueberries, guava, mangoes and breadfruit. It is a hollow-nesting species and its aggressiveness has enabled this species to displace many breeding pairs of native hollow-nesters, thereby reducing their reproductive success. [41] The bird was later introduced to Queensland as a predator of grasshoppers and cane beetles. Can be found just about anywhere but the densest forests. Before sleeping in communal roosts, common mynas vocalise in unison, which is known as "communal noise". This aggressiveness has enabled the common myna to displace many breeding pairs of native hollow-nesters, thereby reducing their reproductive success. Currently, common myna populations in Australia are concentrated along the eastern coast around Sydney and its surrounding suburbs, with sparser populations in Victoria and a few isolated communities in Queensland. and bulbuls (Pycnonotus spp. But as familiar as the house cat is, not many people know it has 38 truly wild relatives, distinct species that include not only the iconic “king of the jungle,” the lion, and the world’s largest cat, the tiger, but also obscure felids like the flat-headed cat, fishing cat, and oncilla. It is also known as "the cane toad of the sky". 302–308. Most starlings and mynas are at least somewhat social, often nesting in loose colonies. The common myna screeches warnings to its mate or other birds in cases of predators in proximity or when it is about to take off flying. (1997) "The impact of two exotic hollow-nesting birds on two native parrots in savannah and woodland in eastern Australia", This page was last edited on 8 December 2020, at 08:49. The roost population can range from less than one hundred to thousands. Cugnasse (2015).- Les populations d’oiseaux allochtones en France en 2014 (3e enquête nationale). and easily takes to nest boxes; it has been recorded evicting the chicks of previously nesting pairs by holding them in the beak and later sometimes not even using the emptied nest boxes. Behaviour The calls includes croaks, squawks, chirps, clicks and whistles, and the bird often fluff… Gregarious and often found in noisy flocks. Introduction: Myna birds were intentionally introduced to Fiji in the late 1800s to control pests on sugar cane crops. & J.M. Originally restricted to the Indonesian islands of Java and Bali, this crested myna has since been introduced to Singapore, Taiwan, and various parts of Malaysia and Indonesia. Common mynas are known to carry avian malaria and exotic parasites such as the Ornithonyssus bursia mite, which can cause dermatitis in humans. In the 19th and 20thcentury common mynas were introduced into many countries worldwide with the intention to reduce the local insect populations. (2019). ): defining best practice in managing invasive bird populations on oceanic islands. The sexes are similar and they are usually seen in pairs. A survey of recent introduction events, spread and mitigation efforts of mynas (Acridotheres sp.) Their rarity makes it hard to find an affordable cage that is specifically made for them. The myna is also called a manana, This article is about the bird. in Spain and Portugal", "9. – Introduced land birds – Te Ara Encyclopedia of New Zealand", "Spatial sorting drives morphological variation in the invasive bird, Acridotheres tristis", "Environmental and Economic Costs of Nonindigenous Species in the United States", 10.1641/0006-3568(2000)050[0053:EAECON]2.3.CO;2, "Crop diversification leads to diverse bird problems in Hawaiian agriculture", Species text in The Atlas of Southern African Birds, https://en.wikipedia.org/w/index.php?title=Common_myna&oldid=993009313, Articles with unsourced statements from November 2010, Creative Commons Attribution-ShareAlike License. Local threats . [25], The common myna uses the nests of woodpeckers, parakeets, etc. Adult primaries are black when new but fade to brown. [19], The common myna thrives in urban and suburban environments; in Canberra, for instance, 110 common mynas were released between 1968 and 1971. Myna definition, any of several Asian birds of the starling family Sturnidae, especially those of the genera Acridotheres and Gracula, certain species of which have the ability to mimic speech and are kept as pets. Name: Acridotheres tristis. The following are species of mynas. Roosting and nesting commensal with humans create aesthetic and health concerns. It walks on the ground with occasional hops and is an opportunistic feeder on the insects disturbed by grazing cattle as well as fired grass fields. Clout, A.R. Representative Species / Lower Classifications. It’s the common myna – also known as the Indian myna – we should be more concerned about. 62. [51] Compared to native hollow-nesting species, the common myna is extremely aggressive, and breeding males will actively defend areas ranging up to 0.83 hectares in size (though males in densely populated urban settings tend to only defend the area immediately surrounding their nests).[52]. Empirical Evidence for the Impact of the Common Myna (Acridotheres tristis) on Australian Birds", http://www.issg.org/pdf/publications/2019_Island_Invasives/SaavedraCruz.pdf, "Introduction and Spread of the Common Myna in New South Wales", "The Current and Potential Distribution of the Common Myna, "Councils assessing backyard traps to catch Indian Mynah birds | thetelegraph.com.au", "A survey of recent introduction events, spread and mitigation efforts of mynas (Acridotheres sp.) Aggressive, often driving away other birds. The common myna (along with common starlings, house sparrows, and feral rock doves) is a nuisance to city buildings; its nests block gutters and drainpipes, causing water damage to building exteriors. The sexes are similar and birds are usually seen in pairs. Common Myna is a native of southern Asia, but they have been introduced in many other parts of the world. [10], The Sri Lankan subspecies melanosternus is darker than the Indian subspecies tristis and has half-black and half-white primary coverts and a larger yellow cheek-patch. [44], In 2019, common mynas were added to the List of Invasive Alien Species of Union concern[1]. Some are downright gregarious and aggressive, especially some of the introduced species. Native to southern Asia, where it is among the most common species. Mynah Birds This text provides an introduction to the family of mynahs worldwide followed by a closer inspection of two of the most common species, the Hill Mynahs (Gracula religiosa) and the Common Mynahs (Acridotheres tristis). [24] Nesting material used by common mynas includes twigs, roots, tow and rubbish. Mynas are stocky brown birds with a shiny black head and shoulders. West (eds.) The time and timespan of arrival and departure, time taken for final settlement at the roost, duration of communal sleep, flock size and population vary seasonally. Escapees from captivity have established feral populations in many regions of the world, including southern Florida, where the species is now thriving in cities and suburbs. [23], Common mynas are believed to pair for life. The pair of bald eagles are a sign of the species' resurgence. [29][30] The time of arrival of mynas at the roost starts before and ends just after sunset. [citation needed]. Within the same species, male mynas are larger than the females. Great Myna. There is a white patch on the outer primaries (longest wing feathers) and the wing lining on the underside is white. [46], The common myna was introduced to both the North Island and South Island of New Zealand in the 1870s. As mynah birds are a larger bird species, they require a lot of room. Preening The common myna or Indian myna (Acridotheres tristis), sometimes spelled mynah,[2] is a member of the family Sturnidae (starlings and mynas) native to Asia. The common or Indian mynah (Acridotheres tristis ) is a native species of south Asia, from Afghanistan, Pakistan, and India, through to southwestern Chinaand Indochina. There is a white patch on the outer primaries and the wing lining on the underside is white. Animal Biodiversity and Conservation 38, Long, John L. (1981). Island invasives: scaling up to meet the challenge, pp. Body length: 23 cm Mynas are not a natural group;[1] instead, the term myna is used for any starling in the Indian subcontinent, regardless of their relationships. To study the invasion genetics and landscape-scale dynamics of A. tristis, scientists have recently developed 16 polymorphic nuclear microsatellite markers [50] using the next generation sequencing (NGS) approach. The common myna can help spread agricultural weeds: for example, it spreads the seeds of Lantana camara, which has been classed as a Weed of National Significance because of its invasiveness. No known major threats to this hugely abundant and widespread species. [12][28] It is a cross-pollinator of flowers such as Salmalia and Erythrina. Dark gray overall with a spiffy erect crest and a bright yellowish-orange bill. The Common Myna (Acridotheres tristis), also called Indian Myna and House Myna, ranges naturally from Afghanistan to Indochina, but has been introduced into tropical and subtropical oceanic habitats around the world. The incubation period is 17 to 18 days and fledging period is 22 to 24 days. [12], During the breeding season, the daytime activity-time budget of the common myna in Pune in April to June 1978 has been recorded to comprise the following: nesting activity (42%), scanning the environment (28%), locomotion (12%), feeding (4%), vocalisation (7%) and preening-related activities, interactions and other activities (7%). In flight, the white tips of the tail feathers and white wing patches are clearly visible. Other related species are the Pagoda mynah, Starlings and Bali or Rothschild's grackle. The bill and legs are bright yellow. Self-sustaining populations of common myna have been found in regions of mean warmest month temperature no less than 23.2 Â°C and mean coldest month temperature no less than -0.4 Â°C, implying that the common myna could potentially spread from Sydney northward along the eastern coast to Cairns and westward along the southern coast to Adelaide (though not to Tasmania, Darwin, or the arid interior regions). A species of bird is dispersed in the south in a random pattern. 2015. [20] Only three years later, a second study found an average population density of 75 birds per square kilometer in the same area.[21]. Martin, J.C. Russell and C.J. Morphometry. Common mynas have been known to use tissue paper, tin foil and sloughed off snake-skin. It's adaptability and success to survive in foreign countries results mainly from being an omnivore and it's robust and belligerent nature. They breed from sea-level to 3,000 m in the Himalayas. A large, black-and-brown myna with white wing patches, yellow bill, and yellow legs. Darker than Jungle Myna, with which it overlaps in both its native and introduced ranges. [9] This species is now placed in the genus Acridotheres that was introduced by the French ornithologist Louis Jean Pierre Vieillot in 1816. They are known to have very loud calls, squeaks and whistles. Both male and female common mynas will fiercely protect both roosts at all times, leading to further exclusion of native birds.
