What You'll Learn
Common mynas are known to eat insects and grubs
The common myna, also known as the Indian myna, is a member of the starling family. It was introduced to Australia in 1883 to combat insect pests such as plague locusts and cane beetles. In southern Asia, where the species is native, common mynas are not generally considered pests, as they follow the plough to feast on the insects and grubs turned up with the soil.
In Australia, however, their fruit-eating habits make them a pest of fruit trees, especially figs. They are also responsible for damaging seedlings in market gardens. The common myna is closely associated with human habitation, often gathering in large groups in communal roosts in roof voids, bridges, and large trees.
The common myna's success in Australia is largely attributed to its opportunistic behaviour and aggressiveness towards other species. They are known to bully other birds around food sources and outcompete them for nesting sites. This behaviour is thought to evict native bird species and even kill their eggs and chicks.
The common myna has a brown body, a black head, and a yellow beak, legs, and bare eye skin. It has large white wing patches that are visible even in flight. Its song is described as "rollicking" and "churning".

They are considered a pest to fruit trees
The common myna, also known as the Indian myna, is a species of starling that was introduced to Australia in 1883. While they are popular in their native countries of India and Southern Asia as crop pest control agents, they are considered a pest to fruit trees in Australia. This is due to their fruit-eating habits, particularly their penchant for figs, grapes, and blueberries, which can cause significant damage to ripening fruit.
The common myna's success in Australia is largely attributed to its opportunistic behaviour and aggressiveness towards other species. They are known to bully other birds around food sources and outcompete them for nesting sites. This behaviour can evict native bird species from their nesting boxes or tree hollows and even lead to the killing of eggs and chicks.
The common myna is also a carrier of diseases such as avian malaria, avian influenza, and salmonellosis, as well as parasites like mites, which can cause dermatitis in humans. Their roosting and nesting habits near residential areas often result in noise complaints and health and safety concerns.
In a nationwide survey conducted in 2005, Australians rated the common myna as the most significant pest, even above contenders such as the cane toad, European rabbit, and feral cat. This perception, however, has been contested, with some arguing that it is based on unreliable information and a lack of scientific research quantifying the bird's actual impacts. Despite this, the common myna is still widely regarded as a pest in Australia, particularly for fruit growers.

They are aggressive and competitive around food sources
The Common Myna, also known as the Indian Myna, is a highly aggressive and invasive species in Australia. Its success in the country is largely attributed to its opportunistic behaviour and aggressive tendencies towards other bird species. The Common Myna is known to bully other birds around food sources, outcompeting them for nourishment and resources. This behaviour is not limited to other species, as they are also known to fight with members of their own kind.
The Common Myna's aggressive nature is further observed in its territorial behaviour during the breeding season, which lasts from August to March. During this period, they aggressively defend their breeding grounds, often evicting native bird species from their nesting sites and even destroying eggs and chicks.
The Common Myna's fruit-eating habits, particularly their penchant for figs, have earned them a reputation as pests of fruit trees. They are responsible for damaging ripening fruit, such as grapes and blueberries, making them a nuisance to farmers and gardeners.
In addition to their aggressive behaviour, Common Mynas are also carriers of diseases, such as avian influenza, salmonellosis, and avian malaria, which poses a threat to native bird populations. Their ability to transmit diseases, coupled with their aggressive behaviour around food sources, makes them a significant concern for the preservation of native bird species and ecological balance.
The Common Myna's aggressive and competitive nature around food sources is a significant factor in their success as an invasive species in Australia. Their bullying behaviour towards other birds, coupled with their territorial defence of breeding grounds, contributes to the displacement and harm of native bird populations.

They are known to carry diseases like avian influenza and salmonellosis
The common myna, also known as the Indian myna, is a highly invasive species in Australia. Its aggressive and quarrelsome nature has earned it the nickname "the rat of the sky" or "the cane toad of the sky". The common myna is known to carry diseases like avian influenza and salmonellosis, which pose risks to both animals and humans. Avian influenza, or bird flu, is a contagious disease that can infect not only birds but also other animals, including humans. It is caused by influenza viruses that spread among avian species and can have severe impacts on both wild and domesticated birds. Salmonellosis, on the other hand, is a bacterial infection caused by Salmonella bacteria. While it typically affects the intestinal tract of birds, it can also be transmitted to other animals and humans, causing salmonellosis food poisoning.
The common myna's behaviour around food sources contributes to the spread of these diseases. They are opportunistic and aggressive, often bullying other species away from food and competing aggressively for nesting sites. This behaviour can result in the eviction of native bird species from their habitats and the destruction of eggs and chicks. The common myna's aggressiveness, combined with their ability to carry and transmit diseases, makes them a significant concern for native bird populations and overall ecological balance.
In addition to avian influenza and salmonellosis, the common myna is also known to carry avian malaria (Plasmodium and Haemoproteus spp.). This disease can drive some native bird species to extinction. The common myna's role as a disease vector further underscores the importance of effective management and control strategies to mitigate their impact on the environment and native wildlife.
The common myna's success in Australia can be attributed to its adaptability and aggressive behaviour. They were introduced to the country in 1883 to combat insect pests in cane fields. However, their fruit-eating habits, particularly their fondness for figs and grapes and blueberries, have made them a pest in fruit orchards and market gardens. The damage they inflict on ripening fruit contributes to their reputation as a problematic species.
The common myna's ability to carry and transmit diseases like avian influenza and salmonellosis underscores the importance of public health and safety concerns. Their aggressive behaviour around food sources and nesting sites can facilitate the spread of these diseases to other bird species and potentially to humans. As a result, the common myna is often regarded as a pest and a threat to the well-being of native bird populations in Australia. Effective management and control measures are crucial to mitigate the impact of this invasive species on the local ecosystem.

They are monogamous and aggressive during the breeding season
The common myna, also known as the Indian myna, is a monogamous bird species. They are native to India and South Asia and were introduced to Australia in 1883. In their native countries, they are popular as they feed on insects and grubs, providing natural pest control.
In Australia, however, the common myna is considered a pest due to its fruit-eating habits, particularly in fig trees. They are known to be aggressive and quarrelsome, often bullying other birds and even their own species. This behaviour extends to the breeding season, which lasts from August to March. During this time, breeding pairs of common mynas aggressively defend their territory, which is usually the same territory they return to each year. This defence of their breeding territory is thought to contribute to the eviction of native bird species from their nesting sites and the killing of eggs and chicks.
The common myna's aggressive behaviour during the breeding season is not limited to other birds. They are also known to attack non-predatory mammals such as cattle, sheep, and wallabies. This behaviour, coupled with their ability to carry diseases like avian influenza and salmonellosis, has led to their reputation as one of the most invasive species in the world.
The common myna's success in Australia can be attributed to its opportunistic behaviour and aggressiveness. They are known to outcompete other species for food and nesting sites. Their ability to adapt and thrive in new environments has earned them nicknames like "the rat of the sky" and "the cane toad of the sky," reflecting their negative perception in Australia.
