Tunnel of Love (and Bones)

The nest of the male Great Browerbird, found in Northern Australia/nearby islands. I dare say this is the most elaborate of all birds nests, though there are others worth consideration. Note the use of color and most critically, perspective - they pile up more items further away from the entrance to the next to give the illusion of greater size.
What we do for love! The male of the species spends most of the time not eating/sleeping working on his nest. There's even some mild form of training that occurs when young males will watch/assist an older male with his nest. And all for the ladies, of course. She'll come by, inspect it, and if it meets her standards, SEXY-TIME. Otherwise, she flies off to inspect other nests, and the loser bird gets to work trying again.

You see this behavior in almost all creatures that reproduce sexually - display. Competition. Seemingly over the top behaviors. It's hardwired into us, and is one of the means that evolution works its way through our various populations.

I note for consideration that it seems to me it's the males of almost every species that engages in these elaborate courtship behaviors, or even more, biological displays - consider the peacock. Whereas the females of most every species are drab and/or uninterested in any courtship displays. Except in humans. Sure, males of the species must acquire money in order to acquire a rocking Camaro in order to obtain a mate, but the females of the species go to equally great lengths in order to woo a mate - think of plucking eyebrows. Perhaps greater lengths - witness the cliched sitcom couple of the fat loser man with the plucky, hot wife.

What gives, humanity?
