The bird species known for its remarkable ability to mimic a wide range of sounds, including human speech, is the **common or Indian hill myna**, scientifically known as Gracula religiosa. Hill mynas are members of the starling family and are native to South and Southeast Asia.
Hill mynas have a remarkable vocal ability and can imitate various sounds with remarkable accuracy, including the calls of other birds, animals, and even human speech. They are known for their clear and melodious whistles, as well as their ability to mimic words and phrases with surprising clarity and intonation.
Due to their impressive vocal skills, hill mynas are often kept as pets and are popular among bird enthusiasts. However, it's important to note that wild populations of hill mynas are threatened by habitat loss and capture for the pet trade, and they are listed as near-threatened by the International Union for Conservation of Nature (IUCN).
