In Wampar, spoken among the people who live in Markham Valley of New Guinea, it is referred to as the birisis.

[2] Its natural habitat is subtropical or tropical moist lowland forests—typically primary rather than secondary forests.

[3] Its call consists of a series of rapid notes at a constant pitch; it starts loud and gets progressively louder.
