Land vertebrates as invasive species on the islands of the South Pacific Regional Environment Programme. The Common Myna is sometimes confused with the slightly larger (24 cm - 29 cm) Noisy Miner, Manorina melanocephala. Pest animal risk assessment: Indian myna Acridotheres tristis., Australia: The State of Queensland, Department of Employment, Economic Development and Innovation, 20 pp. http://www.jncc.gov.uk/page-3660, Wildland Consultants. This website may contain names, images and voices of deceased Aboriginal and Torres Strait Islander peoples. Once established in their new range, common mynas have proved adept at spreading locally, both on their own or with human help, even in some instances managing to overcome significant water barriers. Bio-control the Last Resort for Hawaii's Plants. Common Myna. Easily spotted due to its bright yellow crest; Their natural call, which can be heard in the Aviary, sounds like the bleat of a goat. Control and eradication attempts also suffer from lack of knowledge of basic aspects of the biology of common mynas in their non-native ranges, especially in terms of reproductive capacity and demography and how these are affected by interventions aimed at reducing their numbers, ideally to zero (Feare 2010a). Cook Islands Biodiversity Database, 2007. Undated. Cook Islands Biodiversity & Natural Heritage. found in St Helena did not kill mynas instantly or humanely). 1996. Mynas are distinctive in that they walk rather than hop. Grassland is thus a preferred habitat and common mynas frequently feed on managed lawns, in park grassland, sports fields, grass airstrips and similar areas. Newey, Philip. An omnivorous open woodlands bird with a strong territorial instincts, the myna has adapted extremely well to urban environments. Monson, V. 2005. Where common mynas are already established in areas where they are not native, decisions must be made whether to take any action against them or not. Life span averages four years in the wild, possibly up to 12 years for some individuals (Markula Hannan-Jones and Csurhes, 2009). The common myna may be confused with a native Australian honeyeater known as the yellow-throated miner (Manorina flavigula). ACT 2003. Ongoing studies in the Seychelles by Jildou van der Woude and colleagues (pers. Common Myna: This large stocky starling has a black hood and a patch of bright yellow bare skin behind the eye. http://www.issg.org/cii/Electronic%20references/pii/Myna_review_final.pdf. Common mynas are believed to have both positive and negative impacts on biodiversity. McKenzie HR, 1979. Non-native species in UK Overseas Territories: a review. 465-473. [English title not available]. Griffin AS, 2009. Overall body plumage is chocolate-brown, but the under tail and tip of the upper tail and wing patches are white. They construct nests in tree hollows, crowns of living and dead coconut trees, clefts in cliffs, walls buildings or thick vegetation, such as dense clumps of New Zealand flax Phormium tenax in St Helena (Ashmole and Ashmole, 2000). (2012), on the other hand, examined a long term dataset of bird abundance in Canberra, Australia, which covered a period of introduction and establishment of common mynas in the study sites. The common myna is readily identified by the brown body, black hooded head and the bare yellow patch behind the eye. The Common Myna is brown with a black head. Conservation Biology, 21(5):1248-1257. http://www.blackwell-synergy.com/loi/cbi. The myna has been deliberately introduced to continental landmasses and islands with warm temperate to tropical climates, ostensibly to control invertebrate pests (Case 1996; Veltman et al., 1996; Feare and Craig, 1998). Éditions du Museum, Paris. Eradication of small populations has been achieved (Saavedra, 2010), but eradication of a population of hundreds of mynas has only so far been achieved on Fregate Island, Seychelles (Canning, 2010). In 2000, the Common Myna (Acridotheres tristis) was declared amongst the top 100 of the world's most invasive species by the International Union for the Conservation of Nature (IUCN).Common Mynas have the potential to cause significant negative impacts on biodiversity. From Tahiti common mynas have colonised neighbouring islands (Lever, 1987), a process that may still be continuing. Further beneficial considerations stem from their popularity as pets and in religious use for merit release. A variety of birds have done this and it is an interesting example of evolution that is often dismissed by some naturalists. 2004. 65(1): 17. It has a yellow bill and legs. Physical barriers will exclude common mynas from localised food sources, such as food stores, fruit gardens and restaurants that are under cover. Most of the common myna’s indigenous range lies within the tropics and subtropics, up to 30°N, but recent range extensions in Turkey and southern Russia have reached about 40°N. The Birds in Backyards website lists 30 species of bird that are sometimes found in towns and cities. Common mynas were introduced to control cattle ticks (McCulloch, 1992) but their region of origin is not stated. Markula, A., M. Hannan-Jones & S. Csurhes. Introduced at Melbourne from south-east Asia between 1862 and 1872, it established quickly, with several other introductions occurring until the 1950's. Pierce R.J.; Blanvillain C. 2000. Global register of Introduced and Invasive species (GRIIS), Benefits from human association (i.e. Myna trapping trial report: summary and recommendations., Israel: Israel Nature and Parks Authority, 4 pp. Extrait du compte-rendu de la seconde mission. http://www.nzfsa.govt.nz/acvm/publications/notes/drc1339-bird-study-notes.pdf. Acclimatisation societies: In New Zealand acclimatisation societies were active in importing wild animals, including, in the 1870s, common mynas. Elepaio 39: 69–70. Counsilman JJ; Nee K; Jalil AK; Keng WL, 1994. (2013b) highlighted the value of habitat restoration for the management of myna populations and for safeguarding native birds in mainland situations. 2007. First campaign for Common Myna (Acridotheres tristis) control in the island of Mallorca. Snakes may also take myna eggs. Gilbert M; Sokha C; Joyner PH; Thomson RL; Poole C, 2012. Females lay four to five eggs in a clutch. In New Zealand they lay eggs from mid-October to early March, with the highest egg-laying activity from November to January. The head, neck and upper breast of the adult is glossy black with the head sporting an erectile crest. CSN 1981. Its head and neck are black, with a short yellow beak. While there are clearly uncertainties regarding the common myna in St Helena, it is known the several consignments were imported from Mauritius to Ascension Island (Ashmole and Ashmole, 2008) around 1815, to control insects (Lever, 1987). ACT, Australia: Office of the Commissioner for the Environment, 7 pp. This was probably one of the world’s first attempts at biological pest control (Hawkins and Safford, 2013). B., Hails, C. J., & Counsilman J. J. Common Indian Myna Website., Australia: Australian National University. Azalées Editions. However, this has not been subjected to experimental investigation with common mynas. Come and explore what our researchers, curators and education programs have to offer! There are birds intermediate between tristis and melanosternus in the southern Indian states of Kerala and Tamil Nadu. All attempts to introduce common mynas to new places, for any reason, must be discouraged. Acridotheres tristis., France: Inventaire national du Patrimoine naturel. CSN 1984. Série A, Zoologie, Tome 127. In flight it shows large white wing patches. While recent expansion within Israel is most likely associated with release of captive birds from a zoo (Holzapfel et al., 2006), the timeline of spread around the western countries of the Arabian Gulf and into Iraq and Turkey (Holzapfel et al., 2006) does not exclude the possibility of range extension from Iran, with the establishment of new populations facilitated by agricultural and urban development, and associated irrigation, in the Gulf region. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. 2009. It has a yellow bill, legs and bare eye skin. Generate a print friendly version containing only the sections you need. Pet/aquarium trade: The pathway to the Spanish islands has been via pet shops and later escapes from the home cages. It presents a threat to indigenous biota, especially on islands with endemic fauna, but also in Australia and elsewhere. When several references are cited, they may give conflicting information on the status. If this is the case, however, this would have pre-dated the introduction of this subspecies to Durban. Images: Kate Grarock Glossary Species abundance The number of individuals of a species in an area, landscape or ecosystem Species richness The number of different species in an area, landscape or ecosystem CASE STUDY: Common myna impacts Tidemann. Live Arico, 2008. This study also accounted for the effects of changes in habitats associated with expansion of human influence during the course of the dataset. http://cookislands.bishopmuseum.org/search.asp. However, the perception of negative impacts has proved difficult to translate into good evidence and many instances of threats to wildlife and people are little more than anecdotal. Baker and Moeed (1979) found that common mynas introduced on North Island, New Zealand, showed variations in several morphological characteristics, some of which were sex specific, relating to latitude (birds being larger in the warmer north), precipitation and altitude. Canberra, Australia: Bureau of Rural Sciences. 1985. Common myna can also be a residential nuisance as they build nests in spouting and drainpipes (Stoner, 1923). These two groups of mynas can be distinguished in the more terrestrial adaptions of the latter, which usually also have less glossy plumage except on the heads and longer tails. Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. The influence of traditional Buddhist wildlife release on biological invasions. The Australian Museum and the Kwainaa’isi Cultural Centre have just completed a bird survey of East Kwaio, Malaita, Solomon Islands. Positive impacts concern the pollination of flowers, especially of trees, and the dispersal of the seeds of native plants (Feare and Craig, 1998). The common myna prefers warmer climates. Notornis 41: 49. In the first two countries, these introductions occurred at a time when ‘Acclimatisation Societies’ were actively importing a variety of birds from Europe. These observations should be highly instructive in determining the impact of common mynas on endangered species that are introduced to an island where mynas were already established. The Australian National University. Te Manu, 25:2. brown, with glossy black head, neck and upper breast Foster, J.T. Ashmole P; Ashmole M, 2000. Undesirable aliens: factors determining the distribution of three invasive bird species in Singapore. Robinson. Concerns over environmental safety and efficacy in population management indicate a need for more knowledge on the chemical’s use in island ecosystems. In Australia it is said to prefer human-modified woodland (Tidemann 2007e) and its density is positively correlated with increasing urbanisation (van Rensburg et al., 2009, Lowe et al., 2011). Ibis, 150(Suppl. Muséum national d'Histoire naturelle [Ed]. Failed introductions were made at Launceston, Tasmania in 1900 and later in 1955. obs.). In flight it shows large white wing patches. Invasive Species Specialist Group of the IUCN Species Survival Commission. According to Ali and Ripley (1972) common mynas were introduced to the Andaman Islands around 1867 and possibly also to the Nicobars; the origin would most likely have been India and the birds are said to have been introduced as scavengers to assist in the removal of rubbish. Western and American Samoa, Kiribati, Palau) and this spread, sometimes accompanied by the jungle myna Acridotheres fuscus, may continue with increasing human connectivity between islands. In flight it shows large white wing patches. Both species have yellow bills, legs and bare eye skin, but the common myna is brown with a black head, and in flight it shows large white wing patches, whereas the noisy miner is mostly grey (Australian Museum, 2003). Temporal Limitations on Social Learning of Novel Predators by Indian Mynahs, Acridotheres tristis. The common myna (also known as Indian myna) is noted for its aggressive ousting of other birds from nesting sites, and its rapid adaptation to a variety of geographical conditions. Ethology, 115:287-295. Breeding biology of North Island robins (Petroica australis longipes) on Tiritiri Matangi Island, Hauraki Gulf, New Zealand. Acridotheres tristis Manu Kavamani, Common Myna. Classified Summarised Notes. Trimestrial report on the reproductive success of the Omama'o or Tahiti flycatcher (Pomarea nigra). it is a human commensal). This approach has proved beneficial on some small islands where endemic birds have been introduced to establish insurance populations (Samways et al., 2010), and Grarock et al. Classified Summarised Notes. The new field guide to the birds of New Zealand. While reserves provide excellent environments for the myna in Australia and are home to large numbers of mynas during the breeding season, in the winter months mynas find refuge in surrounding suburban areas (Pell and Tidemann, 1997). 2003. Myna are excellent mimics and copy sounds, other bird calls, and even people. Hails CJ, 1985. Commm. The common myna (Acridotheres tristis), also called the Indian myna, is a highly commensal passerine that lives in close association with humans, being most successful in disturbed habitats. At such times, common mynas can become agricultural pests (Peacock et al., 2007), feeding on the ripening fruit and seeds of plants such as figs, papaya, mango, chilli, dates, apple, pear, tomato, and cereal crops such as maize, wheat and rice.

The generic name Acridotheres is from the Greek akridothera, loosely meaning ‘locust hunter’. Bali Myna has special characteristics. At about this time common mynas were also introduced, for pest control, to Raratonga, but the origin of the birds is uncertain; both Tahiti and New Zealand have been postulated (Lever, 1987). Heather B.D. Where studied, its movements are generally very limited. Beichle, U. R. 1989. http://www.issg.org/database, IUCN, 2012. Behaviour The calls includes croaks, squawks, chirps, clicks and whistles, and th… . In their native range of southern Asia the myna forms flocks in rural areas, which feast on insects and grubs turned up in the cultivated soil by the plough (Australian Museum 2003). Common mynas are believed to pair for life (Sengupta, 1982) and maintain the same territory from year to year. Common myna on Upolu: first record for the Western Samoa Islands. In southern Asia Common Mynas are not generally considered pests, as flocks follow the plough to feast on the insects and grubs turned up with the soil. Common mynas pose a human health risk as they can carry bird mites such as Ornithonyssus bursa and Dermanyssus gallinae that may infect humans.
