1 PARASITES OF FALCO ELEONORAE: PREVIOUS AND LATEST INFORMATION A. Diakou 1, J. Fric 2, M. Papazahariadou 1, T. Dimalexis 2 1 Laboratory of Parasitology and Parasitic Diseases, Faculty of Veterinary Medicine, Aristotle University of Thessaloniki, Greece 2 Hellenic Ornithological Society, Vas. Irakleiou , Athens, Greece

2 Falco eleonorae (Eleonora’s falcon) migratory (Mediterranean - East Africa) migratory (Mediterranean - East Africa) Greece hosts more than 80% of the global population (> pairs) Greece hosts more than 80% of the global population (> pairs) nests in natural rock cavities located on small islets, larger island, interior land nests in natural rock cavities located on small islets, larger island, interior land diet: big insects / migratory birds diet: big insects / migratory birds parasitic diseases: low importance but for a “Rare” species can be of particular interest

3 Aims Review of previous information on parasitic fauna Parasitological examination of F. eleonorae in Greece (EU “Life Nature” project “Conservation of Falco eleonorae in Greece”)

4 Materials and Methods August – September 2006 Islets of Sporades and Cyclades Islands in Aegean Sea Faecal samples from 23 nests Ectoparasites of 2 nestlings

5  merthiolate-iodine- formalin sedimentation  zinc sulphate flotation  Ziehl-Nielsen stained smear inspection The identification of the parasites was based on morphological criteria Materials and Methods

6 Results (faeces) 20 out of the 23 samples: positive (86.95%) 1 parasitic species: 8/23 2 parasitic species: 8/23 3 parasitic species: 4/23

7 Results (feaces) Protozoa (4/23) Isospora spp. (2/23) Caryospora spp. (1/23) (1/23)

8 Trematoda (10/23) Neodiplostomum spp. (1/23) Nematostrigea spp. (7/23) Results (feaces) 2/23 1/23

9 Nematoda (11/23) Serratospiculum spp. (7/23) Synhimantus spp. (1/23) Physaloptera alata (2/23) Results (faeces) (1/23)

10 Cestoda, cysticercoid (1/23) Acarina (9/23) Results (faeces)

11 Hyppoboscidae (1/2) Mallophaga (2/2) Results (ectoparasites)

12 Parasites of F. eleonorae: Parasites of F. eleonorae: only few studies Wink et al. (1979): Leucocytozoon toddi, microfilaria, Haemaphysalis numidiana (Ixodidae), Ornithophila gestroi (Hyppoboscidae), Laemobothrion tinnunculi, Degeeriella rufa (Mallophaga), mite (Acarina) Martínez-Abraín and Urios (2002): absence of blood parasites

13 The present study The present study Faecal examination: high prevalence and various species of parasites (potential threat) Ectoparasites: same taxon with the previously reported: Hyppoboscidae and Mallophaga are common in this bird species

14 F. eleonorae: the most important bird species hosted in Greece Species' long-term protection  study of its biology and of the factors that can threaten its conservation status Parasites can represent a serious problem  Detailed recording of F. eleonorae ‘s parasitic fauna  Measures for their limitation
