This species nests in colonies, which frequently contain hundreds of pairs. Its nests are bored in rotting or dying tree trunks in woodpecker style. It eats fruit, insects, and grain.[2] Grosbeak starlings are highly vocal, at their colonies and in feeding flocks.[2]
The grosbeak starling was first described by the English ornithologist John Latham in 1801 under the binomial nameLanius dubium.[4]
New populations, derived from escaped cagebirds, have been found breeding in Kalimantan in Borneo, and in Java.[3]
