Chestnut-breasted munia, Bully bird
The chestnut-breasted mannikin (Lonchura castaneothorax ), also known as the chestnut-breasted munia or bully bird (in Australia), is a small brown-backed munia with a black face and greyish crown and nape. It has a broad ferruginous breast bar above a white belly. The species is found in Australia, New Caledonia, Indonesia, and Papua New Guinea. This species has also been introduced to French Polynesia and France.
In Australia, the chestnut-breasted mannikin is known as a bird of reed beds and rank grasses bordering rivers, in swamp, in grassy country, and mangroves. It is commonly found in cane fields and cereal crops. In dry seasons, it is seen in arid country but always near water. It is also found in grassy woodland.
John Gould wrote of it (quoted in Cayley 1932):
In New Guinea, the chestnut-breasted mannikin is a bird of drier areas and does not usually seen in jungle roads and clearings where other munias such as grey-headed mannikin are found.
In French Polynesia, it is well established as an introduced species, and its habits have developed somewhat differently, indicating the adaptability of the species. It is widespread on the bracken-covered hill slopes, in pastures and gardens (it is not a garden bird in Australia), on cultivated land and wasteland, in forest ecotones and coconut plantations (Lever 1989).
