Taxonomy
Habitat
Cultivated open areas, gardens, parks and scrubland.
Behaviour
The female builds a cup shaped nest of plant material lined with fine grasses, in matted vegetation on the ground, low in a tree or bush, or in a niche in a wall. 2-3 brown-blotched greenish-blue eggs are laid, and are incubated by the female for 12-14 days. The male helps in feeding the chicks.
In Brazil these sparrows are parasited by Molothrus bonariensis, who has a marked preference for their nests to lay its eggs.
The diet includes seeds, fallen grain, insects and spiders. It is a ground feeder.
