Myna

Mynas are a diverse group of birds belonging to the starling family, known scientifically as Sturnidae. They are passerine birds, which means they are part of a large group of perching birds. While many people use the name "myna" to describe various birds, it is not a single natural group. Instead, the term is used for any starling found within the Indian subcontinent. These birds are highly adaptable and can be found in many different environments. They are important to study because they show how different species can evolve and spread across the globe.

The history of mynas in South and Central Asia is a story of two different migrations. Scientists believe the Indian subcontinent was colonized by starlings twice during their evolution. The first group of birds was related to the coleto and Aplonis lineages. Millions of years later, a second group arrived. These later birds were related to the ancestors of the common starling and the wattled starling. You can tell these two groups apart by looking at their physical traits. The second group has longer tails and less glossy plumage, except on their heads. They also have adaptations that make them more terrestrial, meaning they are better suited for living on the ground.

The name "myna" itself has a very long history. It is derived from the Hindi word "mainā." This word can be traced even further back to the ancient language of Sanskrit, where the word was "madanā." In places like Singapore, these birds are so common that they have local names. In Malay, they are sometimes called "Selarang." In Chinese, they are known as "Teck Meng." These different names show how humans interact with the birds in different cultures.

Mynas have very specific physical characteristics that help them survive. They are medium-sized birds with strong feet that allow them to perch easily. Their flight is described as being both strong and direct. Most mynas are gregarious, which means they enjoy living in social groups rather than alone. They typically prefer to live in open country habitats. To stay healthy, they eat a diet consisting of insects and fruit. Many species also prefer to build their nests inside holes for protection.

There are many different species of mynas, and they vary greatly in appearance. Most have dark plumage, often in shades of brown. However, some species feature bright yellow head ornaments. The Bali myna is a very famous example, though it is in a difficult position. It is currently classified as critically endangered and is nearly extinct in the wild. Other species include the Great myna, the Javan myna, and the Crested myna. There are also "pied" mynas, such as the Indian pied myna and the Siamese pied myna, which often have patterns of different colored feathers.

One of the most fascinating things about certain mynas is their ability to mimic sounds. Some species are considered "talking birds" because they can reproduce various noises. The common hill myna is a well-known example of this skill. When these birds are in captivity, they can even learn to imitate human speech. This ability to copy sounds is a unique trait that sets some species apart from others in the starling family.

Mynas are also known for how they move into new territories. While they are native to parts of Central and South Asia, including India, Pakistan, and Sri Lanka, they have been introduced to many other places. They can now be found in North America, Australia, South Africa, Fiji, and New Zealand. In some of these new areas, like with the common myna, they are regarded as an invasive species. This means they have moved into a new environment and can affect the local ecosystem. Studying mynas helps scientists understand how birds move and how they impact the world around them.
