Grasswrens tend to be birds of spinifex and porcupine grass of the arid interior, and have very limited geographic distribution, reflecting perhaps relic populations isolated by increasingly arid conditions, eventually evolving to become separate species. The emu-wrens occupy a variety of habitats, with the southern emu-wren found in swampy heath and plains thickets of southern Australian coastal belts, while the other two species occupy the arid interior. The fairy-wrens occupy a range of habitats, including tropical grasslands, wet forests and woodlands, and the semi-arid interior. Several species have adapted well to humans and grace the parks and gardens of suburbia.
