The avenue-type bower is quite large. It's decoration varies geographically, it includes bone fragments, snail shells, green fruits, pebbles and many other items including human-made ones. Theft or even desctruction of bower by other male occurs. When the female arrives the male performs a courtship display.
Following mating, females construct nests of a shallow bowl of dead twigs, placed in a low bush or tree. 1- 2 eggs are laid.
