When are juveniles, su menú se compone principalmente de semillas compuestas de helipterum, that you belong to the same family as sunflowers.

Distribution:

Endemic to Australia, where there are four populations, one of which is isolated in the southeast of Western Australia, from the West of the Nullarbor plain up close Kalgoorlie.

Las aves que pertenecen a esta raza occidental también se encuentran en el oeste de Southern Australia, about Ooldea and Colona, ​​pero son probablemente provenientes de escapes.

From the North of Southern Australia, extends to the South of Queensland to the West of the Great dividing range, reaching around to East of Windorah, Charleville, Mitchell and Goondiwindi.

In New South Wales found to the West of the Cordillera Central, y llegando al este de una línea, More or less, that crosses Warialda, Orange and Wagga Wagga (registro fuera de límite al este de Gunning).
