Bank Myna is an Indian bird that bears a scientific name "Acridotheres ginginianus", found in the flocks.

Structure of Bank Myna
Bank Myna is smaller but similar in colouration to the common Myna but differs in having a brick red bare skin behind the eye in place of yellow. It is greyer on the underside and in the presence of a slight tuft of feathers bears some resemblance to the Jungle Myna.

Behaviour of Bank Myna
Bank Myna is found in flocks on the plains of northern and central India, often within towns and cities. Their range appears to be extending southwards in India. The name is derived from their habit of nesting almost exclusively in the earthen banks of rivers where they excavate holes and breed in large colonies.

Body of Bank Myna
The head of Bank Myna is black on the crown and sides and the upper plumage is slaty grey while the underside is lighter grey with pale pink plumage towards the centre of the abdomen. The wing is black but has a wing patch at the base of the primaries and the tips of the outer tail feathers are pale pinkish buff. The naked skin behind the eye is brick red, the legs are yellow while the iris is deep red. The sexes are indistinguishable in the field. Young birds have a browner head and neck.

Habitat of Bank Myna
The native range of the Bank Myna is almost restricted to the Indian states from the Indus valley in the West, to the Gangetic delta in the East and south of the lower foothills of the Himalayan Mountain Range, only rarely being found in sheltered valleys. They are found mainly in the vicinity of open water and their usual habitat is cultivated farmland and open country but flocks will often live within cities, in markets and railway stations. They make use of food scrap disposed by humans, even following catering vehicles at airports to standing aircraft.

Distribution of Bank Myna
The distribution of Bank Myna was formerly noted to be restricted north roughly of a line between Mumbai, Maharashtra and Balasore District in Odisha, but the species may be expanding its range. They are also common in Pakistan in the districts of Sind and Punjab.

Category of Bank Myna
The species name of Bank Myna is based on the name given by Latham from a description by Pierre Sonnerat who described Le petit Martin de Gingi in 1782, referring to Gingee area (Gingee fort) near Puducherry in southern India. Thomas C. Jerdon noted in 1863 that the species did not occur in southern India however the species was recorded in the region in 1914 at Vandalur near Chennai.

Forage of Bank Myna
Bank Mynas are gregarious foraging in flocks, breeding colonially and roosting together in trees. They perch on livestock and live in crowded towns allowing close approach, often picking up scraps in markets and dumps. They are vociferous and use a wide range of calls that include clucks, croaks, screeches, whistles and warbling elements.

Feeding of Bank Myna
Bank Mynas feed on grain, insects and fruits. Like the common Myna, they sometimes follow grazing animals picking up disturbed insects or even ticks on the animals. They feed on ripening crops such as those of sorghum, grape and pearl millet. They feed on a variety of insects, including some that are crop pests such as Achaea janata whose caterpillars feed on castor.

Nesting Season of Bank Myna
Bank Mynas have a nesting season from April to July or August, most birds breeding from May and June. The nest is always built in earth walls, on the banks of rivers, embankments or the sides of open wells. They will sometimes make use of holes in brick walls. Nests have also been recorded between stacked bales of sugarcane stalks. They excavate the nest hole, the egg chamber sometimes 4 to 7 feet from the entrance. The nest is lined with grass, feathers and sometimes snake sloughs. About four of five pale sky blue or greenish-blue eggs is the usual clutch. Two broods may be raised in the same season. The eggs hatch after about 13 to 14 days. Nestlings open their eyes after about 5 days and fledge in about 21 days. About 38% of the eggs hatched into young that fledged in one study.
