Has anyone ever seen a film, with David Attenborough, about the Bower Birds? The way the male bird decorates his bower to attract the female is astounding. Some of the males prefer all one color of whatever they can collect, like the Blue Bower bird will collect nothing but blue flowers, leaves, plastic, ribbon, anything that is blue an arrange them in a lovely pattern. He will spend hours decorating and rearranging his finds till they look just right around the arch to his bower. If a female comes to inspect and does not like it she leaves - so he spends another few hours rearranging again. It is just amazing!
