We are grateful to Gwen L. Brewer, J. C. Elbert, Alison Pearce, Lisa G. Sorenson, Murray J. Williams and H. Glyn Young for contributing unpublished observations. Research at Cedar Creek Natural History Area and in the Bahamas was supported by grants from the National Science Foundation, Ducks Unlimited (Bahamas), and the Graduate School, University of Minnesota to F.M. Funding for the molecular phylogeny work was provided by a National Science Foundation Doctoral Dissertation Improvement Grant, Dayton and Wilkie Funds for Natural History Grants, and a Frank M.

N2 - Although postcopulatory displays are widespread in animals, little is known about their function or the intended receiver. The postcopulatory displays of dabbling ducks are among the best described for any animal group. We documented the presence of initial and additional postcopulatory displays in nearly all dabbling duck species. We then reconstructed the evolution of postcopulatory displays in dabbling ducks using a phylogeny derived from mitochondrial DNA sequences. The display immediately following copulation (the initial display) is highly stereotyped in most species and shows extreme phylogenetic conservation. In contrast, the performance of additional displays is less stereotyped and less phylogenetically conservative. We review the possible functions of postcopulatory displays. Using evidence from display orientation, display form and phylogenetic reconstruction, we suggest that the most likely functions of postcopulatory displays in dabbling ducks are pair bond maintenance, individual identification, or signalling a successful copulation.
