Although less gregarious than many other starling species, tending to live in pairs or in small family groups, the Brahminy starling will congregate in larger flocks during the non-breeding season and around sources of abundant food. It may also roost communally in trees, shrubs and reed beds, and will nest colonially if the availability of nest holes allows (2) (3).
The breeding season runs from February to September, with breeding occurring earlier in the more southern parts of its range, and slightly later in the north. The Brahminy starling is monogamous and both sexes contribute to building the nest, which is typically an untidy structure of grass, dead leaves, paper and other materials, placed in the hole of a tree. The Brahminy starling also uses holes in walls or in the roofs of buildings, and will use nestboxes if no other suitable nest sites are present (2) (3).
The courtship display of the Brahminy starling takes place on the ground, with the male singing and standing erect, puffing out the feathers on the chest and crest and fanning the tail up and down. The female lays a clutch of between 3 and 5, usually 4, pale blue eggs which are incubated by both sexes for a period of 12 days. The chicks are fed by both adult birds until they leave the nest after 18 to 21 days (2) (3).
The Brahminy starling typically feeds on a wide variety of invertebrates, as well as the fruits, berries, flowers and nectar of a range of plant species. Juvenile birds are fed mainly with invertebrates and small amounts of plant matter. The Brahminy starling forages extensively on the ground, often in association with other starlings (2) (3).
