The breeding season runs from October to November (4) and nests are preferentially made within woodpecker holes in the trunks of trees (2). Males become very aggressive at this time (2). Outside the breeding season, Bali starlings could previously be found in flocks of up to 40 birds, often roosting in dense coconut trees (2). Adults feed on ants, termites and caterpillars but also on fruits and seeds (2) (3).
