Hot Headgear

Some guys will do anything to attract a female. Biologists at the University of California at Irvine discovered that a male zebra finch readily submits to the indignity of having a white feather glued to his head because female zebra finches find the ornament irresistible. The experiment suggests that the predilection for crests may be hardwired into the avian central nervous system.
