Cloacal microparasites such as viruses, bacteria and fungi are expected to condition choice of sexual partner, as they can not only affect the expression of secondary sexual traits used in courtship, but they could be also directly transmitted to partners through copulation. We investigated the distribution of three cloacal microparasites (the bacteriumChlamydia psittaciand the yeastsCandida albicansandKloeckeriasp.) among males and females of the sexually plumage dichromaticMalurus cyaneusandSericornis frontalis, and the plumage monochromaticManorina melanophrys.
