Breeding

The female builds a large, round, cup nest in a shrub or tree from very small twigs, lichen and other mosses, and often lined with downy feathers, soft plant material or animal hair. It is bound together with spider silk. The eggs are generally laid between November - May.

Diet

The diet includes nectar of native and introduced flowers, shrubs and trees and also insects.

Vocalisations

Song is a learned mixture of high-pitched scratchy buzzes followed by more melodious whistles and scratchy notes. Typical call is a short, sharp, dry tzip note. A loud pop is made acoustically by the male at the bottom of a territorial dive display.
