Hippoboscid flies (Diptera: Hippoboscidae) on birds of prey in the atlantic forest, minas gerais, brazil

Abstract

Hippoboscid flies are potential ectoparasites of several avian orders, including birds of prey, a group formed by the orders Falconiformes, Strigiformes, Cathartiformes and Accipitriformes. In this study, we evaluated 155 birds of prey that were brought to the Wildlife Rehabilitation Center of Juiz de Fora, Minas Gerais, Brazil, between the years 2016 and 2019. Two species of hippoboscid flies (Ornithoctona erythrocephala and Icosta americana) were found in five species of birds of prey (Megascops choliba, Asio stygius, Athene cunicularia, Asio clamator and Caracara plancus). The average intensity found was 1.4 hippoboscids/bird and Megascops choliba (tropical screech-owl) was the most parasitized bird. This is the first record of parasitism of Asio stygius (stygian owl) by Ornithoctona erythrocephala in Brazil and of Athene cunicularia (burrowing owl) and Asio clamator (striped owl) by Icosta americana. Ornithoctona erythrocephala is recorded here for the first time infesting birds of prey in the state of Minas Gerais, Brazil.
