Avian chatterer is a term used to describe two types of birds: the JAY and the Mynah. The JAY is a small, usually brightly-colored bird with a loud call, found in wooded areas of North America, Europe, and Asia. The Mynah is a tropical bird native to South and Southeast Asia, known for its ability to mimic human speech. Both birds are known for their loud and distinctive calls, which is why they are referred to as avian chatterers.
