Mynas are small to medium-sized passerine birds native to Asia, Africa and Australia. They are known for their ability to mimic various sounds and calls, and are often kept as pets. Synonyms for the word mynas include Hill Myna, Common Myna, Javan Myna, Indian Myna, Bali Myna, and Crested Myna. These different types of mynas have varying physical characteristics and calls, but are all often referred to as simply "mynas". While mynas have gained popularity as pets, they can also be considered pests due to their aggressive behavior and tendency to compete with native bird species for resources.
