abstract = {The role of plumage ornamentation as a signal of parasite infection is a key issue in the evolution of
animal behaviour. Despite the undeniable role of hosteparasite interactions in sexual selection, it is still
unclear how parasites influence the variance in the expression of females displaying multiple ornaments.
Here, by taking advantage of a long-term and individual-based, monitored population of pied flycatchers,
Ficedula hypoleuca, in a Mediterranean area, we investigated the variation in the expression of wing
patch (size) and forehead patch (occurrence and size) in relation to infections with haemosporidian
parasites in breeding adult females. Haemosporidian infection was related to wing patch size, and this
association varied in direction and magnitude depending on the origin of birds (locally born versus
immigrant) and the type of breeding habitat (oakwood versus pine plantation). Specifically, differences
in wing patch size were most evident among immigrant females breeding in the pine plantation, with
noninfected females expressing larger wing patches than infected ones. Regarding the forehead patch, its
occurrence was also modulated by haemosporidian infection through two-way interactions with bird
origin (lower occurrence in locally born females) and breeding habitat type (lower occurrence among
infected than uninfected females in the oakwood, whereas the opposite was true in the pine plantation).
Only bird age predicted forehead patch size. Therefore, in addition to haemosporidian infection, the
expression of these ornaments was related to extrinsic (breeding habitat) and intrinsic (age, origin)
factors, which suggests the existence of trade-offs between physiological responses to infection and the
expression of secondary sexual traits. Overall, our results suggest that plumage ornaments provide independent
and reliable information on the haemosporidian infection status of female pied flycatchers.},
