[edit] Behaviour

[edit] Breeding

When displaying, they jumps vertically from its perch about 1 foot in the air and utters a high pitched 'Pee-Zing' and then with a downward half-somersault lands on its perch again.

It builds a small cup-shaped nest. The clutch consists of 1-4 pale green eggs blotched with reddish brown. Both sexes incubate for 9–10 days and the young fledge about 9-10 days later.

[edit] Diet

The diet consists mainly of grass seeds, but other seeds are included. They will also eat some insects and berries.
