Animal and Insect Body Modification

Although focused primarily on separating humans from nonhuman nature, Etcoff also notes that at least one animal “exhibits a form of dressing” (6): the bowerbird which builds and decorates a bower to attract a mate. Etcoff’s admission in some ways contradicts her assertion that the adornments of dress are uniquely human. It also broaches questions that may connect our evolutionary paths more explicitly to those of the animal world: Are there other species of animals that use ornaments outside their bodies for decoration or disguise? And do these examples begin to redefine our own connections to the natural world and evolution? Do they also reshape the purpose behind the changes we make to our bodies and selves? 

For us, the body modifications explored in American Mary do not separate humans from nature. They demonstrate all too well our connections to it. The multiple species of the male bowerbird, for example, build bowers consisting “of a thatched twig tunnel forming an avenue” decorated with bones, shells, berries, nuts, and stones the male displays to potential mates. They arrange the objects in regular patterns, creating an illusion that seems to increase their size, according to biologists Laura Kelley and John Endler. The bowers are works of art meant only for seducing female bowerbirds, not for nesting and clearly require objects external to the birds to build them. David Attenborough’s documentary, Bowerbirds: The Art of Seduction (2012) highlights the behaviors of multiple species of bowerbirds and demonstrates how deliberately the birds place their artifacts. In one scene, for example, Attenborough moves objects, and a male bowerbird immediately replaces it. 

 Other animals decorate their bodies rather than create external bowers. Sandhill Cranes preen their feathers with mud, turning their gray bodies red or brown during spring and summer. The purpose behind the preening may be related to breeding because it ends when the feathers molt in the fall. And the looper caterpillar ornaments its body with plant parts from the flowers on which it is feeding. According to Dr. Miklos Treiber, the loopers change the flower parts when they move to another flower, as well. Here the plant pieces act as camouflage. Dr. Treibe hypothesized that the looper’s ability to change disguises allows it to have a much more varied diet than some other caterpillars because it isn’t restricted to eating only those flowers or plant parts that it resembles in appearance. Multiple videos document the looper’s amazing camouflage.
