The Common myna (Acridotheres tristis) is a tropical bird with a strong territorial instinct, which has adapted extremely well to urban environments. The range of the Common myna is increasing at such a rapid rate that in 2000 the IUCN Species Survival Commission declared it one of the world's most invasive species and one of only three birds listed among "100 of the World's Worst Invasive Species" that pose a threat to biodiversity, agriculture, and human interests.
Common mynas can be recognized by their brown body, black hooded head, and the bare yellow patch behind the eye. Their bill and legs are bright yellow. There is a white patch on the outer primaries and the wing lining on the underside is white. The male and female look similar and are usually seen in pairs.
Common mynas are native to Asia with their home range spanning from Iran, Pakistan, India, Nepal, Bhutan, Bangladesh, and Sri Lanka; as well as Afghanistan, Uzbekistan, Tajikistan, Turkmenistan, Myanmar, to Malaysia, Singapore, peninsular Thailand, Indo-China, Japan (both mainland Japan and the Ryukyu Islands) and China. These birds are typically found in a wide range of habitats with access to water; they inhabit open woodland, mangroves, grasslands, farmlands, orchards, and urban areas.
