Parasitismaffects the growth, reproduction, and susceptibility to other infections of thehosts. Birds are hosts of a great variety of parasites, an interaction that is relevant in thedispersion of the birds and their pathogens. We studied the diversity of ectoparasitesand endoparasites in three species of thrushes (Turdidae) with differences in theirmigratory behavior in subtropical Andean forest. We worked with Catharus ustulatus(Neartic latitudinal migrant), Turdus nigriceps (Austral latitudinal migrant of theNeotropics.) and T. rufiventris (resident) in the Selva Montana of Yungas, Tucumán,Argentina. We inspect edevery host in search of ectoparasites, made blood smears forthe study of hemoparasites and collected dregs for coproparasitologicals analysis. Wereported: (1) Ectoparasites: Ixodes auritulus eI. pararicinus in both T. rufiventris and T.nigriceps and Ixodes sp. in the three especies of birds; (2) Hemoparasites: microfilariain both Turdus; (3) Endoparasites: cestodes (Dilepissp. and Wardium sp.) in both Turdus,three species of nematodes (e.g. Syngamus trachea and T. rufiventris, SuperfamilyTrichostrongiloidea in both Turdus and Order Spirurida in T. rufiventris), and two speciesof coccids of the Isospora genera in T. rufiventris and C. ustulatus. The diversity ofprasites by species was related to the number of tested individuals, being T. rufiventristhe most infested and C. ustulatus the less infested. Our results suggest that theinteractions between parasites and thrushes are complex, and that although they areclosely related species, their life histories could be influencing the nature and extent ofthe infestation.
