Insect ectoparasites of the Red-backed Shrike Lanius collurio in the Iberian Peninsula

Of the 26 Red-backed Shrike (Lanius collurio) sampled with the aim of characterizing insect ectoparasites, five birds were parasitized by louse flies. Two species were identified, Ornithophila metallica and Ornithomya fringillina. The first species is reported for the first time in the Red-backed Shrike, and the second represents a new host association in the Iberian Peninsula.
