Diet
Their diet consists mostly of insects and spiders during the summer months, switching to berries and fruit in the winter. Very active feeders in low shrubs, sometimes hovering.
Breeding
The female chooses the nest site, which is usually on the ground under dense vegetation, but may be in a shrub, low tree, fern, or vine. The nest is an open cup formed from grasses, shredded bark and moss, lined with fine grass and hair. The clutch consists of 4 to 5 eggs which are incubated for 11 to 13 days. Both parents feed the young.
