The white-crested elaenia Elaenia albiceps chilensis Hellmayr, 1927 is a bird than in winter is distributed from southeastern Colombia to the Amazon regions of Peru and Brazil, and during the summer migrate to Chile to reproduce in to their full extent. Currently, there are three parasites described, the lice Ricinus sp. and Tyranniphilopterus delicatulus, and the tick Ixodes auritulus. The objective of this study was to evaluate the parasite fauna of white-crested elaenia in Chile. Over the course of more than a decade (2001-2012) a total of 20 white-crested elaenia were collected from different chilean localities to which were practiced necropsy parasitic in search of helminths and ectoparasites. Additionally, between 2006 and 2014, 106 birds were captured using mist nets to be examined and detect the presence of ectoparasites. The parasites found were the mites Anisophyllodes elaeniae, Trouessartia elaeniae, and Analges sp. in 51% of the birds (n=106), while 24% were infested with the lice Tyranniphylopterus delicatulus, Menacanthus cfr. distinctus and Ricinus cfr. invadens. The helmints Viguiera sp. and Capillaria sp. were found in five (25%) of the necropsied birds. With the exception of T. delicatulus, all parasites found represent new records for the white-crested elaenia and also to the biodiversity of Chile.
