The male satin bowerbird builds a stick structure, known as a bower (distinct from a nest), where courtship and mating take place. They curiously decorate their bowers using blue or shiny objects.

When courting, the male satin bowerbird prances and struts around his bower. He offers the female items from his collection of blue objects, while making a series of hissing, chattering and scolding noises. Mating takes place in the avenue of the bower, and the male may mate with several females in a single season. -- NSW Government Office Of Environment and Heritage
Question: Is the male satin bowerbird's bower-building behavior innate?
This is essentially a "nature vs. nurture" question. E.g. If there were no other males around for him to learn it from, would he still build a bower? If so, where did he get the idea from? If there were no females around, would he still bother to build it?
