What are the differences between the common myna and the bank myna?

The common myna and the bank myna are different in many ways. The common myna is comparatively larger with a brownish purple plumage. It has a black head. But the bank myna is smaller and bluish-grey in colour. It has some bare skin behind its eyes, which is brick red in colour. In the common myna, this skin is yellowish.

          The common myna is a bold and adventurous bird, mostly found in towns, villages and cultivation lands. They are courageous enough to enter even houses. But bank mynas are milder in their manner.

          The common mynas build nests in holes and they roost communally in tall grasses. They eat invertebrates, fruits, nectar from flowers and even garbage. But bank mynas dig holes in earthen banks of rivers and build their nest in them. Common mynas are found in almost all parts of India. Bank mynas tend to be concentrated in the northern and central regions of the country.
