Summary

Production of secondary sexual traits is a key component of reproductive investment in many sexually reproducing species. In this chapter, we have illustrated the secondary sexual traits and behaviours that are implicated in mate choice; the potential meaning of colourations of females and of their eggs as postmating sexual traits; and the signalling role of colourations in young kestrels. We have also described the biochemical bases of body colourations and the physiological costs associated with their production.
