Abstract

The goal of the present survey was to improve the scarce knowledge regard the endoparasites of raptors in Chile and South America. Thus, necropsy was performed on 14 chimango caracara Milvago chimango temucoensis from Los Riós Region, Chile. From all examined birds, 78.6% were positive to helminths. The species identified were Capillaria tenuissima, Pterothominx sp., Baruscapillaria falconis, Cosmocephalus obvelatus, Skrjabinoclava sp., Synhimantus (Dispharynx) nasuta, Synhimantus (D.) sp., Synhimantus (Synhimantus) sp., Paracuaria adunca, Procyrnea spinosa, Porrocaecum depressum, Contracaecum rudolphii sensu lato, Stephanoprora sp. and Polymorphus mutabilis. All species listed, with the exception of C. tenuissima, P. spinosa and P. depressum, are new records for the chimango caracara. Furthermore C. obvelatus, Skrjabinoclava sp., S. (D.) nasuta, S. (D.) sp., P. adunca, C. rudolphii s. l., Stephanoprora sp. and P. mutabilis all are new records for Neotropical raptors.
