Their popularity as a cage bird has led to many escaped birds establishing themselves. They have been introduced to Taiwan where they are considered an invasive species, eating native insect species and showing aggression towards native bird species.

In Asia, their habitat is dense undergrowth especially in bamboo forests. In Hawaii, they are common in valley forests or on the ridges of the southern Ko'olaus, and tend to nest in undergrowth or low trees of lowland broadleaf forests.

It is loud and clear, with a variety of phrases, and often mimics other birds. They also make a 'Tck' call in alarm or when foraging. One of the first recordings of a bird song that was ever made was of this species. This recording was made in 1889 from a captive individual using an Edison wax cylinder by Ludwig Koch in Germany.

They feed on insects in the wild but in captivity feed on boiled and dried legumes with egg yolk and raw meat.
