Low prevalence of chewing lice (Phthiraptera) in wintering populations of the reed bunting Emberiza schoeniclus (Aves: Passeriformes: Emberizidae) in the Iberian Peninsula

The reed bunting is a passerine bird of the Palearctic region, some subspecies suffer a decline in their populations. Four species of lice have been cited in reed bunting, but lice studies have not been carried out in the Iberian Peninsula. Between 2018 and 2020 a wintering population of the reed bunting is sampled in the center of the Iberian Peninsula through mist nets. Lice were collected directly from birds by a visual body examination. Of the 208 reed buntings sampled, only four individuals were parasitized. We find two species: Menacanthus chrysophaeus, which is the first record in Iberian lice, and Brueelia blagovescenskyi. Lice are not associated with the sex or age of the birds. The prevalence obtained is low compared to other European populations. This difference can be explained by the phenology of the subspecies, the migratory populations have a lower load of lice than sedentary populations.
