A versatile and supreme opportunist, the omnivorous bank myna consumes a wide variety of food types, including frogs, snails, earthworms and other animal matter, as well as fruits and seeds (2). In urban areas it scavenges on the ground amongst people in busy markets or at refuse heaps, and in rural areas it is often found following ploughs to feed on upturned insects (7). It also regularly settles on the back of cattle to remove ticks from them. As a highly sociable species, the bank myna often feeds in large flocks and gathers into large roosts, usually in reedbeds during the winter or in tall trees or buildings at other times of the year (2).
The bank myna generally breeds between May and August, with monogamous pairs forming at the start of each season (2) (3). It excavates a long, narrow tunnel in which to build its nest, almost exclusively in an earthen bank or cliff, with the tunnel often connecting to others within a large breeding colony (2) (7). The bulky nest is constructed out of grass, feathers and refuse and stuffed into the end of the tunnel (2) (3). Usually three to five glossy, pale blue eggs are laid and incubated for around 13 days, mostly by the female (2) (3). Both adult birds cooperate to feed the chicks, which fledge from the nest around 20 to 22 days after hatching (2).
