In India, where the Common Indian Myna originated, it is called the farmer’s friends because it eats insects that destroy crop plants. The name myna comes from a Hindi word, mainaa meaning a bird of the starling family, Sturnidae, to which mynas belong. Mynas in India are also regarded as symbols of undying love, because they often pair for life and maina is also sometimes used as a term of endearment for young girls.
Common Indian Mynas and some other species of myna, particularly Indian Hill Mynas, Gracula religiosa, are accomplished mimics and can learn to talk. For this reason mynas have been taken to many parts of the world as cage birds.
