Question

Bower birds are unique to Australia. These ground dwelling birds build elaborate grass nests and decorate them with brightly colored objects (often bits of trash and plastic) to attract a female. The birds use all sorts of colorful items and arrange their displays to try to be most appealing to the female (either using all one color of item or creating a rainbow jumble of plastic trash!) and arrange them artfully to attract females. The females choose their mates based on the brightness and elaborateness of the male’s nest displays. Why might these birds have evolved into such fantastic animal architects?
