Distribution

Sind, Pakistan, on the West, covering the greater part of northern India, east to Bangladesh, south to approximate latitutdes of Mumbai, Maharashtra (19N) / Balasore,Orissa (21N), except for drier regions in Rajasthan. Distribution is patchy, but most commonly in major river valleys. Mostly resident but with regular seasonal local movements in some areas. Individual stragglers documented from Kandahar, Afghanistan, and Chennai, India, the latter may have been an escaped cage birdcite book

Gregarious, often in flocks even during breeding season. Usually very tame and confiding, often seen on railway stations, sauntering confidingly along platforms, in and out of the feet and baggage of passengers, picking up bits of food. Haunts municipal refuse dumps for scraps and tidbits and attends on grazing cattle for insects. Also seen in markets (e.g. Old Delhi), surreptitiously hopping onto vendors' handcarts to steal scraps. Often following herds of cattle.

Voice somewhat softer than that of Common Mynacite book

Food

Fruit, grain, and insects. Can be very destructive to ripending crops of Sorghum (jowar). An important additional insect pest, recorded among stomach contents in Bihar, is larvae of the moth Ophiusa melicerte, highly injurious to castor.

Nesting

* Season: May to August, principally April to June.
* Nest: Pad of grass and rubbish, often including bits of snake slough, stuffed in the widened chamber at the end of a horizontal earth tunnels drilled in steep earth banks of rivers, sides of disused brick kilns, earthen wells, as well as other holes in masonry. Often breeds in colonies of fifty or more pairs, along with the Common Myna.
* Eggs: 3 to 5, glossy pale blue.
