The only problemwas, it was not for her that he then landed in aflurry of quacks and wingbeats, or for her that hedashed off surprise attacks on his fellows. It was,rather, for another for her preening rival acrossthe Bavarian lake. Poor goose. Will she mate withthe gander of her dreams? Or will she trail him foryears, laying infertile egg clutches as proof of herfaithfulness?

In most species, after all, they take ons hardest chores such as carryingyoung, incubating eggs and tending newborns. Often they can produce only a few young in alifetime. (Given half a chance, most males wouldspawn thousands.) So its no surprising that theladies are choosy. They want to match theircharacteristics with those of a successful mate. Hemay flap his wings or join a hockey team, butsomehow he must show that his offspring will notlikely be last to eat or first in predatory jaws. Strolling through the Australian underbrush thatmorning, she had seen nothing that might catch afemale bowerbirds eye. True, several males alongthe way had built avenue bowers twin rows oftwigs lined up north and south. True, they haddecorated their constructions with plant juices andcharcoal. Yet they displayed nothing out front!Not a beetles wing. Not a piece of flower. Thenshe saw him. He stood before the largest bowerand in his mouth held a most beautiful object. Itwas a powder blue cigarette package, andbeneath it there glinted a pair of pilfered car keys. Without hesitation she hopped forward to watchhis ritual dance.
