A very restricted bowerbird of montane forest in the Foja Mountains. Dull brown plumage like other similar species, but the male has a yellow crown, from the forehead to the long, flowing crest reaching the back. Makes a “Maypole” bower with sticks up a sapling. No other brown bowerbirds co-occur. At the bower, male gives a hollow “kok-kokokokokok!” interspersed with a rattle while spreading its crest at the back. Many other sounds also made, including mimicry.
