Flame Bowerbird: amazing courtship display

The Flame Bowerbird (Sericulus aureus), a species native to Indonesia, is a member of the the Ptilonorhynchidae - a group of species with very elaborate courtship displays. I have seen this BBC video before and I may have already posted it here. So it goes. I find it remarkable that this behavior and a host of others are coded in this tiny brain.
