In this chapter I want to explore the role of ornamental traits in females. They pose a bit of a conundrum, as they are not really predicted to exist—at least until recently. From a simple sexual selection point of view, female ornaments should be selected against by males because inconspicuous females suffer less predation and are more likely to care for their offspring successfully. Yet, countless species show ornaments in females. Are they adaptations of some kind or just the side effect of a genetic correlation? And what information do female ornaments convey to males?
