They forage on the ground, mainly eating seeds and insects. Outside of the nesting season, they often feed in small flocks. While nesting, these birds may feed far from the nest; feeding areas are not defended.

The male sings from an open perch to indicate his ownership of the nesting territory. The song is a "Bzzzz bzzzz za za".
