Nonnatives - Common Myrna

Common Myna - Acridotheres tristis

 

Florida's Nonnative Wildlife. Species detail.

First year: 1983

Extirpated year:

Established status: Species are present but not confirmed to be breeding. Population persists only with repeated introductions and/or escapes of individuals.

Estimated Florida range: 8 counties  At least 10 years, 6 counties  Less than 10 years

Statewide trend: Unknown status

Threats to natives: Nests in tree or cavity nests in communal groups, competing with native species. Mynas sometimes attack Purple Martins at martin houses (Florida BBA). This species seems to spread aggressively and can be serious pests of crops and orchards. It also serves as reservoirs or sources of bird malaria (Florida BBA). Because of their history of establishment and negative ecological impacts, mynas (Acridotheres spp.) have been prohibited from importation into the United States (Bates and Busenbark 1970).

Species Account: The Common Myna is native to southeastern Asia but has been introduced onto almost every tropical or subtropical oceanic island and Australia, where it is mostly found in open country and human environments. In Florida, populations remain small and widely scattered and tend to prefer shopping mall parking lots (Florida BBA). Mynas are omnivorous and feed on fruits, seeds, insects, and human food (Long 1981). They nest in tree cavities, buildings, crowns of palms, large signs, and broken lights (Long 1981, Florida BBA).

Habitats: Central or core urban area, Low density suburban development, areas peripheral to core urban areas, and small towns, Agricultural habitat
