Summary

Breeding density, synchrony, and experience are expected to influence the frequency of extrapair paternity in birds. Female tree swallows can influence the fertilization success of extrapair males by active selection and rejection of copulation partners. We suggest that this ability limits the predicted effect of various ecological factors on the frequency of extrapair paternity.
