Description	We investigated the hypothesis that the common cuckoo selects host pairs of good phenotypic quality. As cuckoos may select hosts within a population non-randomly based on external cues reflecting their foster abilities, we predicted that great reed warbler pairs parasitized by the cuckoo would exhibit higher quality than unparasitized ones. We evaluated two different parameters indicating host quality: body condition and characteristics of host eggs. We found that parasitized females showed significantly better body condition. Moreover, the likelihood of being parasitized increased with decreasing colour variability within clutches: parasitized females allocated costly blue pigments to eggshells more equally compared with unparasitized ones. In highly mimetic systems, cuckoos may choose to parasitize hosts with eggs displaying low intraclutch variation, both because this leads to reduced rejection and because these hosts are of high quality.
