The Common Myna (Acridotheres tristis) is a medium-sized bird belonging to the starling family, native to parts of Asia. It measures approximately 9 to 10 inches in length and weighs between 3.5 and 4.5 ounces, with males generally being slightly larger and heavier than females. These birds have a distinctive appearance with dark brown plumage covering most of their bodies, highlighted by a contrasting yellow patch of skin around their eyes and base of the bill.

Distinguishing field marks of the Common Myna also include white wing patches that are visible in flight and a white-tipped tail. Their robust build and short legs contribute to their distinctive silhouette. Additionally, they are known for their vocal abilities, producing a wide range of sounds including whistles, squawks, and mimicry of other bird species, which adds to their distinctiveness.

The Common Myna is highly adaptable and has successfully established introduced populations in various regions worldwide, including Australia, North America, and islands in the Indian and Pacific Oceans. While they are primarily sedentary birds, some populations may undergo seasonal movements or local dispersals in response to changes in food availability or breeding conditions.

In their native range in Asia, Common Mynas are often associated with urban areas, agricultural land, parks, gardens, and open woodlands. They are frequently observed in large flocks, particularly during the non-breeding season, where they forage for a diverse diet consisting of insects, fruits, seeds, and scraps of food. They are also known to feed on small vertebrates.

Breeding populations of Common Mynas typically construct nests in tree hollows, buildings, or other cavities, where they lay eggs and raise their young. Their opportunistic feeding habits and ability to adapt to a variety of environments have contributed to their success as colonizers in new territories. However, their introduction into new areas can have negative impacts on native bird species and ecosystems, leading to competition for resources and potential disruptions to local biodiversity.
