Acridotheres fuscus is native to India and south-east Asia and is now established in many Pacific islands. Acridotherea can be translated as "grasshopper hunter" - presumably an indication of its major food source in some parts of its native region. It is perceived as a problem to agricultural sectors dependant on crops. Both rural villages and urban areas are at risk of invasion. They feed off rubbish and food scraps and nest in any available spaces in houses and buildings. This behaviour and their close association with human habitations combine to cause a wide variety of problems for humans.
The jungle myna is a 22 to 24cm grey-brownish bird with a tuft of feathers forming a small crest on the forehead and at the base of the bill which is not normally present on the common Indian myna (Acridotheres tristis). It has a black head with the upper areas being more grey-brown and the chin, breast and belly dark ashy-grey. It has a whitish underside, brownish wings and a typical yellow-orange beak. The jungle myna is sleeker than the common Indian myna and lacks the distinguishing yellow patch of skin on the posterior side of the eye. Interestingly, the colour of its iris is yellow in northern India, whereas in southern India, its bluish-white (Feare and Craig, 1999).
Known introduced range: The jungle myna is now also established on some Pacific Islands, including Fiji, Tonga and Samoa (PIERCE 2005). There are new records of both the common myna (Acridotheres tristis) and the jungle myna on tropical islands, most recently on Kiribati (Teariki 2003, in Pierce 2005).

Jungle mynas are known to inhabit altitudes as high 2000m above sea level. However, they prefer lowlands and foothills of well-wooded deciduous, spacious areas which primarily includes tea plantations, villages and coastal plains (Feare & Craig 1999).
Nutrition Mynas are scavengers with a varied omnivorous diet consisting of insects, fruit, seeds and nectar. Mynas also devour insect pests on sheep and cattle, such as ticks (Oliver 1955, Roots 1976). Analysis showed that their stomach content consisted predominantly of grasshopper remains, as well as crickets, termites, beetles, ants, caterpillars and fly larvae. (Hails 1985; Kang et al. 1990; Feare & Craig 1999).
Reproduction In southern India, breeding occurs during the months between February to May, while in the northern regions, April to June-July (Feare & Craig 1999). Typically, two broods are raised at one time with the clutch being 3-6 eggs in size. It is known that both sexes participate in the rearing of their young (Feare & Craig 1999).

Jungle mynas may affect growers of commercial crops due to their love of fruit (Atkinson & Atkinson, 2000). In addition, there is concerns that this species may compete for nest sites with native species.
Both Acridotheres fuscus and A. javanicus have crests, and generally look similar except that A. fuscus has an orange bill with a deep blue base, whereas A. javanicus has a yellow bill, with no blue base (Robson C. 2000). The two species were at one time considered two subspecies: A. f. javanicus and A. f. torquatus (Lever C. 1987).
The jungle myna Acridotheres fuscus is similar to the common myna A. tristis, but is darker and slimmer, with an orange beak and no yellow skin around the eye. Both species have large white patches in the wings and tail.
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. Pesticides should always be used in a lawful manner, consistent with the product's label.

Poisons such as avicides (starlacide DRC1339) were used against the jungle myna (Acridotheres fuscus) with highly promising outcomes, in contrast to narcotics (Alphachloralose), herbicide and pesticide. Trapping is a commonly employed tactic. A variety of foraging traps are used. These include the Tidemann trap, decoy trap and the Kadavu trap. In addition, shooting and netting methods are sometimes used (Pierce, 2005).
