Have you collected as much stuff as a Bowerbird this Black Friday? When a Bowerbird bachelor is ready to mate, he builds a nest-like structure called a bower, which he decorates with flowers, shells, stones, cicada wings, and other eye-catching baubles to attract females—even bottle caps and ballpoint pen caps sometimes make the cut! There are 20 Bowerbird species, and 17 build mating bowers, each in a different style. Male satin Bowerbirds (Ptilonorhynchus violaceus) festoon the front terraces of their bowers with shiny or colored objects, preferring those of a vivid blue hue.
