They build a globular nest made of the webs of Stegodyphus spiders as well as silken fibre from various plants. An entrance hole is made on the side and towards the end, a false entry and chamber are constructed below the actual entrance to the nest chamber. The spout at the entrance has a separating septum with the entrance to the actual nest chamber at the upper portion, the septum pushed up with its forehead to close the upper entrance by the bird just before leaving the nest so as to show only the main entrance leading into a blind chamber. This is a defence against snakes and other nest predators.
